She didn't delete the app immediately. But she stopped logging honestly. Hot flashes? She'd note them in a paper journal instead. Sex? She left that field blank. The app became less useful because she couldn't trust where the information went. The relationship had changed.

That moment, when you realize something intimate has been made extractive, isn't paranoia. It's pattern recognition. And the pattern is everywhere once you start looking.

When Wellness Tech Stops Working With You

The Flo case wasn't an outlier. It was a symptom.

In 2023, researchers at Duke discovered that data brokers were openly selling lists of people with depression, anxiety, and other mental health conditions. Some lists included names and addresses. Prices ranged from $275 for small samples to $75,000 for annual subscriptions. You could literally buy a marketing list of people struggling with depression. Lists like these can be used to target people during vulnerable moments. High-interest financial offers, unregulated supplements, or predatory advertising they would never knowingly opt into become easy avenues for exploitation. None of this data came from HIPAA-protected sources. It came from apps, browsing history, and behavioral signals that people had no idea were being collected and sold.

That same year, hospitals faced lawsuits after patients discovered that Meta Pixels,tiny pieces of tracking code,were embedded in patient portals. When you scheduled an appointment or clicked through your medical records, that activity was being transmitted to advertising platforms. The hospitals claimed it was for analytics. The patients felt surveilled during some of the most vulnerable moments of their lives.

These aren't edge cases. A 2022 study published in JMIR reviewed 23 popular women's health apps and found that 87% shared data with third parties. Thirteen percent collected data before users even consented. Only 70% had a visible privacy policy at all. These weren’t obscure apps , the study reviewed top-downloaded women’s health apps on the major app stores.

The infrastructure isn't broken. It's working exactly as designed,to turn your body into data that serves someone else's business model.

The Breach Isn't Technical, It's Relational

In the first essay of this series, we talked about the difference between a playlist and a pulse. Your playlist is a preference,it reveals taste, maybe mood. Your pulse is your body. It reveals when you're stressed, when you're recovering, when something might be wrong. The intimacy isn't comparable.

When wellness tools treat your pulse like your playlist, feeding both into the same advertising machinery and applying the same surveillance logic, they break something fundamental. Not just privacy in the legal sense, but trust in the human sense.

My friend who stopped logging her hot flashes wasn't worried about a specific harm. She couldn't articulate exactly what Meta might do with behavioral metadata about when she opened her period tracker. But she knew the relationship had changed. The app had gone from co-pilot to informant.

That shift happens in an instant, and it's nearly impossible to reverse. When people discover their intimate data has been shared without their real understanding, they don't just change their privacy settings. They disengage. They log less. They lie. Or they leave entirely.

This is why the surveillance model isn't just ethically problematic,it's strategically self-defeating. The more accurate your data needs to be, the more it requires genuine trust. And trust, once broken by the discovery that your co-pilot was actually a spy, doesn't recover with a revised privacy policy.

What a Co-pilot Actually Looks Like

A co-pilot helps you navigate. It reads the instruments, spots patterns you might miss, suggests course corrections. But it doesn't report your route to someone else. It doesn't sell your flight plan. And it definitely doesn't use your altitude to serve you ads for oxygen masks.

That metaphor isn't just rhetorical. It describes a fundamentally different technical architecture.

When your wellness data works like a co-pilot, it processes information locally,on your device, where you control it. It identifies patterns that matter to you: recovery trends, sleep quality over time, how your body responds to different routines. It helps you understand what's working and what needs adjustment. But it doesn't require that data to leave your control to be useful.

This approach is sometimes called "local-first" or "privacy by design," but those terms make it sound more complicated than it is. The core idea is simple: your body data should serve your goals, not someone else's.

When you track sleep in your forties and that data informs insights in your sixties, it should do so without ever living on a server that could be breached, sold, or subpoenaed. When you notice patterns between stress and recovery, the system should highlight them without transmitting raw biometric signals to analytics platforms. When you choose to share information with a doctor or partner, that should be an active decision,not a default buried in fine print.

This isn't about hiding. It's about belonging to yourself.

Why Architecture Matters More Than Policy

Every major wellness tech privacy scandal of the past five years has involved companies that had privacy policies. Flo had one. The hospitals with Meta Pixels had them. The apps selling data to brokers had them. The policies existed, and they were technically accurate. Users had, in the legal sense, consented.

But consent theater isn't consent. When a privacy policy requires a graduate degree to parse, when sharing is opt-out instead of opt-in, and when the default setting is "share everything," the policy becomes camouflage for extraction.

Real privacy doesn't come from better policies. It comes from architecture that makes harmful practices impossible by design.

When data never leaves your device, there's no server to breach. When there are no third-party tracking SDKs embedded in the product, there's no hidden pipeline for information to leak through. When sharing requires an explicit choice rather than an overlooked checkbox, consent becomes meaningful.

This architectural approach does more than protect privacy,it creates the foundation for long-term relationships. If you're building technology meant to serve someone from age 45 to 75, you need infrastructure that can maintain trust across decades. That means systems where the user retains control, where data doesn't accumulate in ways that create compounding risk, where the business model doesn't depend on monetizing intimacy.

This is also why privacy-by-design creates sustainable competitive advantage. Trust isn't a feature you can add later. It's a structural attribute that emerges from how the system is built. Companies that understand this are creating moats that matter,the kind that compound rather than erode over time.

The market is starting to recognize this. Health and fitness apps already convert at 30–43% in app stores,significantly higher than most categories, suggesting users are willing to pay for tools they trust. Meanwhile, regulatory pressure continues to mount. The Flo verdict wasn't a fluke. Several U.S. states have now passed dedicated consumer health data laws, signaling a broader regulatory shift toward tighter protections. It's a signal that the legal and social costs of surveillance-based models are becoming unsustainable.

Trust Unlocks What Surveillance Can't

Here's what shifts when your wellness data actually works like a co-pilot:

You use it honestly. You log the symptoms that matter, track the patterns that feel significant, share the context that makes the data meaningful. You're not performing wellness for an algorithm. You're working with a tool that serves you.

That honesty makes personalization possible,not the marketing kind that targets you, but the kind that actually adapts to how your body works. When the system knows that your recovery takes longer after high-stress weeks, it can adjust expectations and suggestions. When it recognizes that your sleep quality drops before you feel the physical effects, it can flag the pattern early.

But that kind of genuine, useful personalization only works if you trust the tool enough to give it accurate information. And you only trust it when you know where the data goes,and where it doesn't.

This is the foundation that makes adaptation possible. Not just tracking what you do, but understanding what your body is telling you and helping you respond. That's where we're headed next: how technology that understands context can guide without controlling, illuminate without exposing, and help you maintain the kind of wellness that actually lasts.

Reclaiming Partnership

My friend went back to paper. Not because she's anti-technology, but because she couldn't find a digital tool she could trust with that level of intimacy. She tracks her cycles in a notebook now, the way her mother did, and in a post-Roe landscape where reproductive data can be subpoenaed in some jurisdictions, the stakes aren’t theoretical. It works, but she's lost the pattern recognition, the ability to see trends over time, the early signals that a good system could illuminate.

She's waiting for technology that works the way it should have all along,where the architecture makes trust possible, not just promised. She isn’t alone. Millions of people are waiting for the same thing: tools that treat the body as something to serve, not something to harvest.

Wellness technology should feel like partnership, not surveillance. It should amplify your ability to understand and respond to your body, not turn your body into a product. When your data works like a co-pilot instead of a spy, something fundamental changes: the tool becomes trustworthy not because of what it says, but because of what it can't do.

Because technology that knows you without owning you transforms wellness into something else entirely: a relationship that lasts.

That opens up a question worth asking: What becomes possible when your wellness tech actually knows you,and only you know it back?

That's where adaptation lives.

An eighty-year-old friend of mine still travels internationally every month. She keeps a pace that makes her younger friends tired just hearing her itinerary. When she learned what we were building at Cirdia, she didn’t ask if she could be a beta tester. She insisted. For her, wellness isn't about extending capacity. It’s about protecting the freedom she’s already earned.

My partner, at sixty, approaches it differently. He’s working harder than ever to maintain strength and muscle mass, noticing how recovery stretches longer than it used to. Every workout now includes a calculation: how to push enough to stay strong without stealing energy from tomorrow. He wants the numbers. They help him see what’s working.

And then there’s a friend in her early fifties, learning to read her body’s new signals during menopause. When hot flashes cluster, her sleep suffers for days afterward, cascading into everything else. She’s learning to interpret patterns she never had to notice before. Other friends are navigating the in-between, adjusting to new sleep rhythms, caring for aging parents, rediscovering what “fit” even means in a body that keeps changing its mind.

Same general life stage. Completely different rhythms, priorities, and measures of success. Not a monolith, but a constellation.

The Wide Middle

Call it midlife and beyond, roughly 40 through 75 and older. It’s the stage where wellness tools fail fastest.

Nearly four in ten fitness trackers are abandoned within six months, but the drop isn’t even across age groups. Around 40% of adults under 35 use a wearable device, compared with only 17% of adults over 50. Engagement falls as we age, even among people who once used these tools daily.

Research on exercise motivation shows why. Younger users often respond to competition and external rewards. With age, motivation becomes more intrinsic—focused on personal meaning, enjoyment, and sustained health rather than streaks or scores. The tools don’t adapt to that shift, so users quietly set them aside.

These shifts in motivation mirror what’s happening physically. Midlife is also the span where bone density, muscle preservation, cardiovascular health, and balance all matter deeply. But how they show up, when they shift, and what we focus on vary widely from person to person. Some are building capacity for adventures ahead. Others are maintaining the independence they have. Some are catching subtle changes before they become problems. Others are rebuilding after health events or major transitions.

The variation isn’t predictable by age alone. It’s shaped by biology, circumstance, and what the body is saying right now. You can feel it if you’re paying attention.

Bodies That Change the Rules

Midlife and later life aren’t static chapters. They’re laboratories where the rules of the body rewrite themselves, sometimes slowly, sometimes overnight.

For women, menopause isn’t a moment but a multi-year transition that reshapes energy, sleep, temperature regulation, and recovery. Hot flashes don’t just interrupt comfort; they disrupt sleep architecture in ways that echo through daily life. For men, testosterone’s gradual decline shifts muscle maintenance and recovery in subtler but steady ways. Yet most wearables still apply the same default thresholds to everyone.

Muscle preservation becomes an active practice. According to NIH research in 2023, we lose between three and eight percent of muscle mass per decade after 30, and the rate accelerates after 60. Bone density peaks in our 30s and declines from there, especially sharply for women post-menopause. Balance, the quiet skill that once required no thought, starts demanding attention. These aren’t failures of maintenance. They’re transitions. And they’re exactly when understanding patterns matters most, because wellness habits built now compound over decades.

What’s striking is how differently these shifts unfold. For some, the changes are subtle: a few more minutes of stretching, a slightly earlier bedtime. For others, they arrive as sharp reminders: a strained tendon, a restless night, a new medication that alters recovery. The through-line isn’t decline. It’s variation.

That variation isn’t a problem to fix. It’s a signal to follow. And yet, that’s exactly where today’s wellness tools lose their way.

The Loyalty Opportunity

We talk about this period as if it were a single demographic. But it’s not a lane. It’s a landscape where health, capability, and independence shift with every contour of age and circumstance.

The industry calls this diversity “hard to serve.” That’s backward. Sports markets learned long ago that specialization creates loyalty—running watches for runners, cycling computers for cyclists, climbing apps for climbers. No one called those segments difficult. They called them opportunities.

Midlife and beyond need a different kind of specialization—not by sport, but by life pattern. Tools must adapt to changing bodies and goals. Systems must protect intimate health data as fiercely as they track it. Both are achievable when technology is built around the person, not the platform.

People in midlife and beyond don’t churn because they’re fickle. They churn because the product stopped fitting. As earlier data shows, many devices are set aside within months—a symptom of design that doesn’t evolve with its users. The loss isn’t just hardware. It’s trust, and with it, decades of potential loyalty.

The market still treats that as a niche problem. It’s not. It’s the biggest opportunity in wellness. Design something that grows with people and they’ll stay for decades. A 45-year-old who finds a tool that adapts could still be using it at 75. That’s not a product cycle. It’s a lifetime relationship.

Closing the Loop

Midlife isn’t a monolith. It’s a moving target, and that’s its power. The market that calls it complicated keeps mistaking complexity for confusion. We don’t abandon wellness tools because we change. We abandon them because the tools don’t change with us.

Adaptability is how we stay connected to the long arc of our own health. But adaptability only works when it’s built on trust. Trust that the tool understands context. Trust that our patterns belong to us. Trust that our data will never be used against us.

These transitions are personal. You notice them before anyone else does, which makes the question of who else sees your data even more pressing. A system that doesn’t understand context can’t be trusted with patterns. And a tool that knows this much about you must earn, and keep, your confidence.

Technology that understands context doesn’t need to control it. It can guide, illuminate, and protect. That’s the point.

That’s where we’ll go next: what it means to build wellness technology that works like a copilot, not a spy.

If you’ve seen my short update video, you know that we’ve moved from early design renders to real, wearable prototypes for our Day Device, Night Device, and charging stand. These models are now in wear testing, helping us understand comfort, materials, and real-world usability before we finalize hardware and assemble the fully functional devices.

Hardware Progress

Our Day Device is built to feel like an everyday accessory - lightweight, elegant, and designed to fit comfortably on a woman’s wrist.

Our Night Device is soft, low-profile, and secured with a breathable fabric band that doesn’t catch on sheets - because most of us take our jewelry off at night, not sleep in it.

This week, we finalized and are sending out the circuit board (PCB) orders. These boards are the core electronics that bring the sensors and system logic to life. Once we receive them, our engineering focus will be on testing and validating that all components perform exactly as expected.

Only after those boards are confirmed will we move to order our first fully functional prototypes - the complete, working versions of the devices.

While that manufacturing process runs its course, our team will be expanding the firmware, the software that runs on each device, to prepare for seamless integration between the hardware and the Cirdia app.

The App: Private by Design

Alongside the hardware, our Cirdia mobile app is now installable on both iOS and Android.

It connects to our prototype devices via Bluetooth and captures sensor data such as steps, movement patterns, heart rate, temperature, and sleep trends - and it is processed locally on your phone.

What does that mean? Well, it means your biometric data is not stored on our centralized servers, and because we never have it, we can easily promise that it’s never shared or sold. That’s our principle of privacy by architecture - not just privacy by policy.

Provisional Patent Filed: Privacy and Adaptive Wellness Architecture

We recently filed a provisional patent application covering Cirdia’s privacy-first architecture and adaptive wellness system for midlife and beyond.

This filing formalizes how our software interprets data directly on the device, combining transparency, personalization, and privacy to generate insights that stay under your control. It also outlines how our Wellness Modes adapt to each user’s goals and context over time.

Introducing Cirdia’s Wellness Modes

At the heart of Cirdia are three Wellness Modes - the foundation for how the system supports different dimensions of wellness across the seasons of your life.

Activate - For building capability and energy.

Helps you strengthen your baseline: movement, stamina, recovery, and confidence in daily life.

Sustain - For stability and rhythm.

Supports consistency and balance - the patterns that keep you feeling well, rested, and independent over time.

Transform - For focused, intentional change.

Designed for short seasons when you want to reset, build new habits, or reach a goal, with progress tracking that’s motivating but never intrusive.

Together, these modes form a flexible framework that keeps Cirdia personal. You’re not locked into one path; you can shift between modes as your priorities evolve. It’s wellness on your terms, grounded in your patterns and powered by privacy.

Looking Ahead

In the weeks ahead, we’ll be testing the new PCBs, validating the electronics, and expanding our firmware in parallel. Once everything checks out, we’ll move to produce our first fully functional prototypes that combine all the elements - hardware, firmware, and the app into one integrated system.

And in January, we’ll open 100 spots only for our Founding Member campaign. This offer is for a small group of women who are excited for Cirdia to come to life and who will follow along closely as we transition from engineering validation to production readiness.

It’s been a steady and thoughtful build - one that reflects how we want the product itself to feel: reliable, respectful, and designed to last.

The fitness tracker you bought with such good intentions. The one that was supposed to help you get healthier, stay motivated, finally crack the code on whatever wellness goal had been nagging at you. The one that cost real money and came with real hope.

And now it just sits there. A reminder of intentions that didn't quite work out - yours, theirs, it's hard to say.

I've been thinking about this graveyard lately. Not because I'm interested in making you feel guilty about one more thing (we have enough of that), but because I think we've been blaming the wrong culprit. For too long, the narrative has been about your willpower. Your commitment. Your follow-through.

But what if it was never about you at all?

The Creeping Surveillance Feeling

Here's what I hear from people who've abandoned their devices: that creeping feeling that something was off. Not the device itself - the physical thing was fine, mostly. But that gradual realization that their body was being watched. Measured. Scored. And they had no idea what was happening with all that intimate data once it left their wrist. This isn't paranoia. It's pattern recognition.

When you're young, invincible, tracking your marathon training - maybe you don't think about it much. But at 45, 50, 55? When the data gets more complicated, when it intersects with health concerns you're actually worried about, when it feels less like fitness and more like surveillance of your aging body? That hits different. There is a name for this that we don't talk about much: the ick factor. That gut-level response when you start to understand how much a device knows about you, where that data goes, and who profits from it.

But here's the thing: the ick factor alone doesn't explain what's happening in all those drawers. Because plenty of people never get to the surveillance worry. They quit long before that, when the daily experience of using the device just stops making sense. They quit because the device loses relevance.

When Tools Stop Fitting Your Life

Studies confirm what our drawers already tell us: nearly 40% of trackers are abandoned within six months.

The standard explanation? We lack motivation. We’re not committed. We didn't want it badly enough.

But I know too many people who desperately wanted these devices to work. Who bought them during a health scare, or a major life transition, or just because they were tired of feeling disconnected from their own bodies. These weren't whims. These were investments - financial and emotional.

So what actually breaks? 

The device loses relevance. Not all at once, but through small mismatches that compound.

I watched a friend try on a new tracker last year. She was smart, capable, and genuinely motivated to understand her health better in her 50s. The device was too big. Not unusable... just big enough that she couldn't imagine wearing it regularly with the clothes she wears to work. She returned it. Not because she gave up on wellness. Because the device gave up on fitting her life.

This happens in layers. The band that irritates your skin by day three. The charging ritual that becomes one more task in your daily litany of tasks. The metrics that celebrate yesterday's step count when you're trying to understand recovery patterns over weeks. The cartoon badges that feel patronizing when you're 50—more like homework than motivation.

I'm a power user. I'll spend hours restructuring an app, buy different bands, customize every setting to translate the device's priorities into my own. But most people shouldn't have to work that hard. And the ones who quit aren't lazy. They're rational.

This is the real problem: these devices are built on assumptions about motivation, bodies, and goals that map to a narrow slice of users. Young. Athletic. Driven by competition and external validation. But research tells us that motivation shifts with age. It becomes more intrinsic, more about autonomy and capability, and the devices, simply, don't adapt.

The Long Arc

Here's what I think is really happening: these devices aren't designed for the long game. They're designed for fitness cycles: three months of training, six months of weight loss, or maybe a year of "getting in shape." They are made for short bursts of intense engagement, measured in closed rings and completed challenges. Those tools are built for sprinters. But midlife needs a sherpa.

And the mismatch goes deeper than time horizons. We're deeply motivated by health and capacity at this stage -just not by the same things that worked at 25. Daily streaks and competitive leaderboards don't speak to someone trying to maintain independence over decades. Cartoon badges don't connect to the authentic drive to keep traveling, keep moving, keep showing up for the people and activities that matter.

What actually connects at this stage of life is understanding. Not yesterday's step count -but noticing that averaging two miles of walking daily seems to correlate with how sharp you feel. Not today's sleep score - but catching that your recovery patterns have shifted over the past month in ways that might mean something. Not a ring you closed—but understanding when your balance is changing before it becomes a problem.

Maybe it's time to stop blaming ourselves for the devices in our drawers and start asking different questions. Not "why can't I stick with this?" - but "what would I actually want from a tool I'd use for a decade?" Not "what's wrong with my willpower?", but "what kind of understanding would help me make choices that align with how I want to age?"

What would it take for wellness technology to feel like it belongs in your life for the long haul?

I've been building privacy-first technology for over a decade, but when I started Cirdia, I realized something fundamental: the trust crisis in women's wellness isn't really a technology problem—it's a governance problem.

Where Promises Go to Die

The pattern is predictable. Companies launch with good intentions, gain user trust, then optimize for extraction as they scale toward a high-multiple exit. It's not malice—it's the inevitable outcome of governance structures that prioritize infinite growth over sustained stakeholder value.

The headlines tell the story: Meta facing jury decisions over Flo privacy violations, 23andMe data vulnerabilities, and that endless cycle of "we take your privacy seriously" followed by policy updates that chip away at protections.

The buck stops at governance. Companies like Johnson & Johnson proved that constraining decisions with core values creates lasting competitive advantage—but that only works when the governance structure supports those constraints. In tech, we've never seen this model succeed with privacy because traditional funding structures eventually force companies to optimize away their differentiating values.

Our Solution: The J&J Playbook for the Modern Investment Era

At Cirdia, we're building privacy-first wellness wearables with a governance structure designed to prevent this cycle. We're applying the Johnson & Johnson approach to tech: let core values guide decision-making. But unlike companies of the past, we've designed our capital structure to support this approach rather than undermine it.

Our approach recognizes a simple truth: founders and investors want exits, and those who take the earliest and greatest risks deserve higher rewards.

Our innovation is a term sheet and structure that honors both stakeholder promises and investor expectations.

We're raising $1.5M in two-part preferred equity. The core security provides a 5x capped return—that's a projected after-tax IRR of over 35%. The second part is a Performance Participation Warrant that offers a potential for additional, performance-based dividends, ensuring uncapped upside. Founders and investors get the exits they want through a community-based buyout, not a high-multiple exit. The company gets governance that can't be compromised by late-stage valuation expectations that would force us to optimize away our core differentiators.

This isn't charity—it's insurance against the "enshittification" cycle that destroys long-term value for everyone except the last buyer in the chain.

Why This Timing Matters

Recent market conditions—from stalled IPOs to high-profile privacy lawsuits—are highlighting risks that weren't fully priced into traditional tech valuations. The regulatory and reputational costs of extraction-based models are becoming material business concerns. Forward-thinking investors are beginning to see stakeholder trust as a quantifiable competitive advantage.

Our Public Benefit Corporation structure provides guardrails that create competitive advantage in a market where consumer trust has become the ultimate differentiator. We're building for where the world is heading: a place where privacy isn't a feature you bolt on but a foundation you build from.

The opportunity isn't to disrupt privacy promises—it's to build promises into the business structure itself.

The Invitation

We're looking for investors who understand that some of the best companies in history succeeded by never compromising their core values—and who recognize that today's investment landscape requires new structures to support that approach.

Our term sheet is designed to deliver a great return while ensuring we can never optimize away the stakeholder trust that drives those returns. We’ve committed in our corporate charter to a board fiduciary duty to facilitate a community-based buyout, providing a clear path to a tax-advantaged exit for all stakeholders. 

If you're interested in being part of a company that can follow the J&J playbook in the modern era, let's talk.

Timing matters. Every dollar committed by September accelerates our manufacturing schedule, ensuring we arrive at Kickstarter not just with prototypes, but with production-ready confidence. That momentum carries into our DTC strategy, letting us scale faster while the market is primed. With a rolling close, the earliest investors directly shape this trajectory.

Our investor materials are available at cirdia.com/invest. We're specifically seeking partners who understand that the future of tech isn't just about better products—it's about better ways of doing business.

"Is Flo a provider of health care? No. Are Flo's users its patients? No. Did Plaintiffs file their claims on time? No. Did Plaintiffs agree to Flo's privacy policy? Yes."

That defense may have been legally sound, but it sidesteps a deeper issue: in wellness tech—especially where women's health is concerned—users aren't just customers. They're people entrusting you with their bodies, routines, and vulnerabilities. Saying "they agreed to the privacy policy" doesn't absolve companies of the obligation to design with care.

The market delivered its verdict on that defense strategy. Just days after a federal judge approved Flo's settlement and dismissed the remaining class action claims, a San Francisco jury found Meta Platforms liable under California's Invasion of Privacy Act, ruling that it had intentionally intercepted sensitive menstrual health data from millions of Flo users via embedded SDKs. With penalties of up to $5,000 per violation, Meta now faces potential liabilities in the billions—roughly half of Fitbit's total acquisition price.

This wasn't an isolated case. The Flo litigation involved multiple defendants: Flurry Analytics (now defunct) settled for $3.5 million, Google settled for an undisclosed sum, and Flo itself had previously settled with the FTC in 2021, agreeing to clearer disclosures and independent privacy oversight (FTC Press Release). The pattern reveals how embedded technologies that developers don't fully control can create massive liability exposure.

Meta's loss establishes a new precedent: even when companies believe they're legally protected, juries may hold them to a higher standard when intimate health data is involved.

The Illusion of Consent

The Meta verdict highlights a critical flaw in how the tech industry interprets user consent. The idea that someone clicked "agree" doesn't mean they understood—especially when the average privacy policy requires a graduate-level education to comprehend. Most privacy policies are legal labyrinths designed to protect the company, not inform the user. Consent in this context isn't trust—it's compliance. The Meta case underscores that a policy on paper, no matter how carefully worded, won't shield a company from accountability if its design choices ignore the spirit of meaningful consent and data minimalism.

In femtech, that gap matters. Because even when data sharing is technically allowed, it may still feel like a betrayal.

How This Happens: The Invisible Leak

Many apps use third-party software development kits (SDKs)—bundles of prewritten code from companies like Google and Meta. These SDKs are often added for analytics, crash reporting, or marketing—but they can also transmit sensitive user data back to external platforms.

Flo's app included such SDKs, and data about menstrual cycles, sexual activity, and fertility intentions may have been exposed as a result (Courthouse News). Even if that data wasn't abused, its unintended transmission is a trust issue—not just a legal one. And often, it's not even intentional—just embedded in the tools apps rely on by default. Defaults shape outcomes.

What many users don't realize is that even when an app doesn't share the content of what you input—like a note or a symptom—you can still be identified through metadata. Metadata is the data about your data: when you opened the app, how often you used certain features, which buttons you clicked, what time of day you logged something. When combined, these behavioral patterns can closely mimic or even predict the real information you entered. This is why even 'anonymized' health data isn't truly anonymous—behavioral fingerprints are often more revealing than the raw data itself.

A third party might never see your exact entry—"cramps on day 24." But they could easily infer your cycle, sleep, stress, or activity patterns based on how and when you use the app. For example, if a user logs in daily and opens the symptom tracker around the same time each month, that behavior alone can signal where they are in their cycle. And if that metadata is collected through a third-party SDK, it often leaves your device whether you know it or not.

This is how systems built for analytics can quietly become systems of exposure—revealing more than users ever intended to share.

Building the Alternative

A growing number of companies are rejecting the surveillance model entirely—designing systems where intimate body data never touches centralized servers. Companies like Cirdia process data locally, on the user's device, with users maintaining complete control over what they choose to share.

This approach requires rejecting the standard toolkit. No Meta or Google SDKs embedded in products. Privacy-first analytics that never track individuals. Clear boundaries between advertising channels and product experiences. These choices require tradeoffs: more infrastructure, fewer shortcuts, and a fundamentally different product roadmap. But they also build real trust—not just legal defensibility.

Why It Matters More Than Ever

This isn't just about one app. It's about the entire ecosystem of wellness tech—especially tools that collect deeply personal data related to women's health, fertility, and sleep. In a post-Roe legal landscape, even inadvertent data exposure can have real-world consequences. The Meta case is a clear signal to femtech and wellness product leaders: meeting the letter of the law isn't enough. We must build systems that make bodily autonomy and digital trust non-negotiable.

Public awareness is growing: most wellness apps aren't protected under HIPAA. When users feel exposed, they don't just stop using your product—they stop engaging with tools that could help them.

The Strategic Imperative

For founders, this represents both risk and opportunity. While users readily trade social media posts or shopping habits for free apps, intimate body data triggers a fundamentally different response. Companies that fail to recognize this distinction face mounting legal exposure and user backlash. Meanwhile, those who understand that biometric privacy isn't just another data category can build defensible differentiation in a market where trust has become the scarcest commodity.

The playbook is emerging: audit your SDKs, minimize data collection, build opt-in pathways, and default to protection. But more fundamentally, it's about recognizing that in wellness tech, trust isn't just a nice-to-have—it's the entire foundation of sustainable growth.

The Agreement That Matters Most

When we build tech that touches people's bodies and private lives, we're not just writing code—we're making a promise. Not simply to follow the law, but to build systems that respect the boundaries of the people who use them.

Trust begins not with a privacy policy, but with the decision to collect only what's necessary—and to build with care when the data is deeply personal.

Because at the end of the day, a body isn't a business model. And once that trust is broken, no court ruling can restore what was lost.

In this new video, we walk through the full evolution:

• Digital design and mechanical planning
• Final renderings of the aluminum casing and band
• Our first physical prototype on wrist and seated in the charging stand

This is the version now going into comfort and wearability testing—and it already feels like a milestone. The band, the weight, the wrist feel: this is the stage where we start learning from real-world use.

The night device is following right behind. We expect to have a similar video showing its physical casing and band within the next two weeks. That version will also begin wearability testing, while circuit integration and full app syncing are still underway. We're aiming to have the fully functional version of the night device ready for testing approximately six weeks later.

We’re currently working on the battery consumption analysis and miniaturization work for that board, threading the needle between function and form in our extra-small casing. It’s a demanding process—but worth it.

In parallel, our privacy-first app architecture is holding steady: no cloud upload, no data harvesting, no ad trackers—just wellness support that runs locally and respects your autonomy.

This phase is exactly what we hoped it would be: focused, deliberate, and guided by real-world feedback.

Here’s what to expect next:

• New video of the night device in physical form (coming soon)
• On-wrist comfort and wear testing with community members
• And potential early gift options ahead of the holidays
• Our presale community opening once full system prototypes are in test mode

We’re not in a rush. We’re in rhythm.

Thanks for walking this with us.

on behalf of the whole Cirdia team

Wellness on your terms.

We believe your technology should greet you with the same care.

For too long, the setup for new devices has felt like a technical chore to be rushed through. The industry's answer has been the "one-click setup"—a process that respects your time but not your individuality. We believe there’s a better way.

At Cirdia, we are designing a different kind of welcome, one that feels like a conversation with our team, facilitated through the app. Its purpose is to understand you, right from the start.

The Emptiness of the "Connect and Go" Experience

When you connect a device and are immediately dropped onto a generic dashboard, you're left in a one-size-fits-all world. You see metrics you may not care about and get notifications that don’t align with your goals. The burden falls on you to dig through settings later to customize the experience—if you even realize it’s possible.

The result is an app that doesn't quite fit, like a jacket off the rack instead of one tailored for you. It works, but it never feels truly yours.

Our Welcome: A Thoughtful Conversation

The Cirdia onboarding experience was designed by us—real people on our team—after listening to hundreds of women's stories. It’s our way of having a brief, guided conversation to understand your needs.

We don’t ask you to be a technician. We ask human questions to learn about your unique "wellness personality." We want to understand:

• How you relate to data: Do you find it energizing or does it sometimes feel overwhelming?
• How you prefer to be supported: Do you thrive on gentle nudges or prefer quiet, hands-off observation?
• What wellness means to you: Is your focus on athletic performance, restorative sleep, or managing your daily energy?

And if you’re someone who prefers to dive right in, that’s perfectly fine. A single tap sets you up with our thoughtful defaults. You can always have this conversation later, anytime you’re ready.

The Cirdia Promise: A Clear Line on Privacy

It is incredibly important that we are crystal clear about what this welcome conversation is—and what it isn’t.

The conversation is about your preferences—how you want the app to look, feel, and communicate with you. This helps the app’s software adapt its interface for you.

It is not about your deeply personal health data. Your weight, your daily logs, your specific biometrics—that information is entered by you after this initial setup and remains private to you and your device, per our core promise. We, the people at Cirdia, never see it. This interaction is designed to personalize your experience while protecting your privacy, always.

The Payoff: An App That Feels Like Yours

Because you took a few thoughtful moments to share your preferences, the Cirdia app feels different from day one. The dashboard is cleaner. The insights are more relevant. The entire interaction feels simpler, precisely because it has been personalized for you.

It’s a powerful partnership from the start. You answer. We adapt.

Help Us Craft the Perfect Welcome

Crafting these questions and creating this welcoming experience is one of the most human parts of our design process, and it's what our team is focused on right now. For this to feel as respectful and insightful as we intend, your feedback is invaluable.

We are preparing to launch our first-ever UX tests focused on these exact onboarding screens. This is your chance to directly shape the foundational interaction of the Cirdia app. To be among the first to participate, please join the Cirdia Inner Circle, where we will be sending exclusive invitations in the coming weeks.

Thank you for helping us build a more thoughtful path forward.

With gratitude,

It’s a fair question. For many, the word "crowdfunding" can bring up a mix of excitement and valid concern. We’ve all heard stories of projects that were delayed, didn’t deliver, or weren’t what they promised. We see that, and we respect the trust you place in any project you choose to support.

That’s why I want to be very clear about our choice. For Cirdia, using Kickstarter isn't a last resort or a simple sales channel. It was a deliberate decision we made on day one, because it has very little to do with traditional funding and everything to do with our two most important values: our independence and our community.

Independence Is Our Bedrock

The standard path for a tech startup often involves seeking money from venture capital firms. While that’s the right path for many, it wasn’t the right one for us. That kind of funding can come with intense pressure to grow at all costs, which often leads to compromising on core values, like monetizing user data.

We refuse to make that compromise.

By launching on Kickstarter, we remain accountable to you, our community, not to a boardroom of outside investors. As a Public Benefit Corporation, our mission to prioritize people’s wellness and protect your privacy is legally bound to our business structure. This path ensures we can always stay true to that promise.

This Is a Community, Not Just a Campaign

This brings me to the most important reason of all: you.

We’ve already begun building Cirdia with you through your thoughtful survey responses and feedback. Kickstarter allows us to make that partnership official. It’s a platform that is built not just for transactions, but for transformation, turning a group of interested individuals into a true community of founding members.

We don’t see our backers as customers pre-ordering a product. We see you as essential partners who are co-creating this solution with us, right from the start.

How This Empowers You

When you back Cirdia on Kickstarter, you aren’t just securing a device at the best possible price. You are claiming a seat at the table. It means:

• A Real Voice: You’ll have opportunities to provide feedback that helps shape our software, features, and future designs.
• Radical Transparency: You get a front-row seat for the entire journey. We’re committed to regular, honest updates that share the challenges as well as the wins.
• Shared Success: You are helping to build a company that listens, and you are sending a message to the entire industry that there is a better way to create wellness technology.

Answering Your Practical Questions

Trust isn't just about philosophy; it's about being straightforward. Here are honest answers to the most common practical questions:

• What happens if you don’t meet your goal? Nothing. Kickstarter is an all-or-nothing platform, which means you will not be charged a single penny unless our campaign is successful.
• When will it actually ship? We are targeting early 2026 for delivery. As a backer, you will receive regular, detailed progress updates every step of the way.
• Can I return it if I don’t like it? Yes. We have created a straightforward and fair return policy because we want you to love what we’ve built together.

Let’s Talk About This, Together

Choosing Kickstarter isn't just about funding our first production run; it's about starting this company in a way that’s accountable, transparent, and built in partnership with the very people we aim to serve.

To continue this conversation, we're thinking about hosting a live, informal "Meet the Team" Q&A call soon, where you can ask us anything about our mission, our background, the product, or this Kickstarter process.

To help us plan, we’d love to know if this is something you’d be interested in attending. There’s no commitment, but your feedback will help us choose the right platform to host a great event for everyone.

Maybe it was the strap digging into your skin while you tried to sleep. Maybe it was the incessant blinking light in a dark room. Or maybe it was the quiet, nagging feeling of being measured and judged by a device that had no real understanding of your life.

If that sounds familiar, you’re not alone. For too long, the world of wellness technology has followed a simple, flawed playbook: build something for a default user, and then maybe—just maybe—tweak it for women.

At Cirdia, we started with a simple, personal conviction: it doesn't have to be this way. I began with my own experiences and frustrations, talking to friends, colleagues, and other founders about this gap in wellness tech. I wanted to validate the idea before a single line of code was written or a design was sketched.

Those early conversations confirmed the hypothesis. Armed with that conviction, we created an initial design for a more thoughtful wellness experience. But we knew that a design without real-world validation is just a theory. So before we went any further, we took that design out into the world and started asking questions.

You Are Sharpening Our Focus

The response has been overwhelming, and our team is reading every single survey answer right now. The results are not just validating our direction—they are sharpening it in real time. Your experiences are confirming our core ideas and are becoming our blueprint for every refinement we make.

The patterns are impossible to ignore.

You’ve been telling us about the fundamental need for comfort. Nearly two-thirds of you shared that your current wearables become a nuisance, especially at night. As one woman so perfectly put it:

“I gave up on sleep tracking because having a bulky watch on my wrist was more disruptive to my sleep than anything else. I just wanted it off.”

You’re also telling us about the constant annoyance of data overload. You want to feel supported by technology, not managed by it. You want insights, not a new list of things to feel guilty about.

“I don’t need another app telling me I failed. I need technology that quietly supports me in the background, understands my rhythm, and doesn’t demand my constant attention.”

These two themes—the physical discomfort and the mental annoyance—are the bedrock of our mission. Your feedback is giving us the confidence and clarity to move forward.

Our Commitment: Support Without Intrusion

Your stories are why Cirdia is built differently.

It’s why we have two separate devices. The Day band is built to support your active life, from the workplace to a workout, while the Night band is designed with a singular focus: your rest. Its minimal, low-profile design is comfort-forward, using a breathable material that rests gently against your skin, so nothing gets in the way of the deep rest you deserve—even as you turn over in your sleep.

It’s also why our app is designed to be simple, not basic. It’s built to give you meaningful insights when you ask for them, but to stay out of your way when you don’t. We believe technology should serve your life, not the other way around.

We’re not here to tell you how to live. We’re here to build tools that help you live better, with more ease and less friction.

Go Deeper: Join the Inner Circle

This process of listening is just getting started, and it’s the most important part of building Cirdia. Reading your survey responses is one thing, but we want to go deeper with those of you who are as passionate about this as we are.

For those who want to have a real impact on our features, design, and philosophy, we’re creating something special. We call it the Cirdia Inner Circle.

The Inner Circle is a dedicated community where you’ll get a behind-the-scenes look at our process, be the first to participate in private UX tests, and have a direct line to our team. It’s for those of you who are nodding your head as you read this, thinking "finally."

If you believe in what we’re building and want to help shape it, you’re exactly who we’re looking for.

A band goes on your wrist — and stays there. One device. All day. All night. One-size-fits-all.

But when we started building Cirdia, we stopped and asked: Does that actually serve how people live?

The truth is: life doesn’t happen in one mode. Your days move differently than your nights. Your needs change hour to hour. And your wellness support should honor that rhythm — not flatten it into a single strip of silicone.

That’s why Cirdia was built differently from the start. Two wellness devices. One system. Designed for your whole life, not just your workouts.

The Day Device: Present with You, Not Pulling at You

During the day, your Cirdia Contour device quietly supports your activity, movement, and focus — while actually looking like something you'd want to wear.

No sweaty rubber. No bulky plastic. No neon rings gamifying your body.

Instead: clean lines, breathable materials, and a display that gives you just enough information to feel connected — without feeling controlled.

You see what matters — your heart rate, your activity, your energy trends — but you aren’t drowning in charts or chasing streaks. You aren’t being nudged, buzzed, or guilted by your own data. You’re present. In your body. In your life.

The Night Device: Built for Rest, Not Disruption

When your head hits the pillow, your wellness needs shift entirely.

You don’t need another glowing screen flashing at you. You don’t need notifications interrupting your sleep stages. You don’t need a band that makes your wrist sweat under the covers.

That’s where Noir, the night band, steps in.

Slim. Soft. Screenless. Silent.

It quietly tracks your sleep, your temperature, your recovery — the subtle rhythms that actually tell us how well your body is restoring itself. And because it's designed only for night, it's free to prioritize comfort, sensitivity, and data that can work gently in the background while you rest.

Why Split the System? Because Life Already Has Natural Transitions

You already change clothes at night. You take off your jewelry. You wash your face. Your body moves through a natural ritual of transition. So why force your wellness tech to pretend it doesn't?

By creating a Day & Night Duo, we’re not adding complexity — we’re honoring your existing flow. In fact, many of our testers have told us it’s easier:

• You get better battery life because each device does what it’s best at.
• You get better data because sensors are optimized for your current state.
• You get better comfort because each band is tailored for the moment you’re in.

This isn’t “more tech.” It’s less friction. And that’s what makes wellness sustainable.

Built for Your Body, Your Data, Your Life

At its core, Cirdia isn’t about the gadgets. It’s about respect.

Respect for how women actually live and age.

Respect for your right to own your own data.

Respect for your rhythms, your privacy, and your choices.

You don’t live in one mode. And you shouldn’t have to force your wellness tools to pretend you do.

With Cirdia’s Day & Night Duo, we’re offering something better:

A system that fits into your life — instead of forcing your life to fit the system.

The Revelation: When I Compared the Fine Print

Unlike most people, I've always been drawn to legal agreements. There's something fascinating about the precision of language, the careful boundaries being established, the dance between protection and permission. I'm that odd person who actually enjoys reading terms of service—each one a window into corporate values and priorities.

So I embarked on a comprehensive audit—downloading, printing, and meticulously comparing the privacy policies and terms of service from every major player in the wearable space. I created spreadsheets tracking key provisions, highlighted concerning clauses, and mapped how permissions flowed across their ecosystems.

What I discovered was deeply troubling. These companies weren't just collecting data—they were claiming sweeping rights to use, change, publish, and share our most intimate biometric information however they wanted. Most disturbing was the almost complete silence on AI training, with few making clear promises about not feeding your heart rate, sleep patterns, and stress levels into larger systems.

The Crucial Distinction: Biometric Data vs. Personal Information

What became abundantly clear through my research was a fundamental problem in how companies handle our most sensitive information. Most wearable companies make no meaningful distinction between your biometric data—the intimate measurements of your body's functions—and other personal information like your email address or birthday.

This false equivalence creates the foundation for deeply problematic data practices. When your heart rate variability is treated with the same privacy protections as your zip code, something has gone terribly wrong.

The Cirdia Difference: Privacy as Our Foundation

At Cirdia, we've taken a fundamentally different approach. We believe your biometric data deserves special protection—not just in policy documents, but in how our entire system is designed. As a Public Benefit Corporation chartered in Colorado, we have a legal obligation that goes beyond profit maximization. Our corporate charter explicitly commits us to:

"Empowering User Agency: Building systems that respect users as competent decision-makers by providing transparent opt-in processes, collaborative research opportunities, and meaningful control over their wellness journey and data sharing choices."

This isn't just aspiration—it's a legally binding commitment that shapes every aspect of our product and business.

We make a clear legal and technical distinction between your biometric data and your account information. Your body's measurements receive fundamentally different privacy protections than your email address or other account details. This isn't just semantic—it shapes how our entire system is built, with local-first processing that keeps your raw biometric data on your device, not our servers.

While some companies like Apple and Oura have taken steps in the right direction, Cirdia was created from the ground up with privacy and user agency as our core design principles—not features added later or compromises made within a different business model.

From Personal Revelation to Industry Contrast

Let me share what I discovered when I actually took the time to decode what other companies are claiming rights to do:

Fitbit/Google: Your Body as a Data Mine

Fitbit's terms state explicitly that when you share content through their services, you grant them "the right to use, copy, modify, publicly display, publicly perform, reproduce, translate, create derivative works from, and distribute your content". That heartfelt journal entry about your health struggles? That's now Google's content to use as they see fit.

Even more concerning, when you use Fitbit with a Google account, your data is handled according to Google's privacy practices. This means your biometric data becomes part of Google's vast data ecosystem—the same one powering their advertising empire. While they have publicly said they won’t combine your biometrics with ads, they have not bothered to make that promise legally binding in either their terms of service or their privacy policy, which means they can try it out and even implement this without consequence.

WHOOP: The Surveillance Business Model

Unlike what the sleek marketing suggests, WHOOP's privacy policy reveals a business model built on surveillance. They collect data through cookies and other automated technologies, including tracking your interactions over time across the web and other services. They and their advertising partners use this information to serve you targeted ads.

Your sleep patterns, recovery metrics, and heart rate variability become inputs for advertising algorithms. WHOOP shares your data with "service providers, vendors who advertise our Services or other WHOOP products, security and fraud prevention consultants, analytics providers, and staff augmentation and contract personnel". That's an extraordinarily broad network of third parties gaining access to your most intimate biometric data.

Most concerning is that WHOOP makes no technical or legal distinction between your biometric data and regular personal information—it's all treated as a resource to be leveraged for business purposes.

Samsung: No Control, No Choice

Samsung's Health terms of service are particularly aggressive in diminishing user control. They "EXPRESSLY DISCLAIM ANY AND ALL LIABILITY" for how your health information is used, while simultaneously reserving the right to "remove or disable access to the Fitbit Service, any Fitbit Content, or Your Content at any time and without notice".

In other words, they can delete your health history at any time with no warning, but accept no responsibility for how that same data is used or shared. This imbalance of power is staggering.

Xiaomi: Your Data, Their Ecosystem

Xiaomi's approach to privacy is particularly alarming for global users. They state explicitly that they "may use and combine the information we collect about you from Samsung Health with data from other services or features you use and your devices, and other sources, to provide you with a better experience". This broad combination of data across services creates comprehensive user profiles.

Making no distinction between biometric data and other personal information, Xiaomi freely shares your information with affiliates and third parties for marketing purposes.

The Real-World Impact of These Policies

These terms and policies aren't just abstract legal frameworks—they have concrete impacts on people's lives:

1. Health Insurance Discrimination: When biometric data is sold or shared with data brokers, it can ultimately influence insurance algorithms, potentially resulting in higher premiums or denied coverage based on activity patterns.
2. Sensitive Life Event Exposure: We've all heard stories of targeted ads revealing pregnancies before women were ready to share the news. These aren't urban myths—they're the predictable outcome of health data being fed into advertising systems.
3. Location Tracking Without Consent: Many fitness apps track your precise location even when not needed for functionality. This creates detailed maps of your movements, habits, and patterns.
4. Perpetual Data Retention: Most fitness platforms retain your data indefinitely, even after you've deleted your account. This creates permanent digital shadows of our physical existence that we can never fully reclaim.

Our Design Principles: Better by Design, Not Just Better Terms

Local-First Architecture: Privacy by Design

Unlike traditional wearables that require cloud processing, Cirdia uses a local-first approach. Your data is processed primarily on your device or your phone. By design, Cirdia does not store your raw biometric data on centralized servers.

This architectural choice isn't just more private—it's more resilient. You don't lose access to your health insights when servers go down or companies change policies.

Transparent Algorithms

All algorithms used in our App are open source or auditable. This transparency extends to how we communicate insights about your health—no black box recommendations or unexplainable guidance.

When it comes to AI and machine learning, we've reimagined the approach entirely. If we ever incorporate model training using your data, we would only do so through a distributed, local-first framework that keeps your raw biometric data on your device. This means the insights and patterns can improve our collective understanding without your biometric information ever leaving your personal sphere of control.

This isn't a technical limitation—it's a deliberate architectural choice that aligns with our core values. We believe distributed AI approaches that respect data boundaries are not just more private but ultimately more innovative, drawing insights from diverse experiences while honoring individual autonomy.

Data Ownership in Practice

You own your data. The App offers tools to visualize, export, or delete your data at any time. This isn't just rhetoric—it's built into how our technology works.

When you choose to share data with Cirdia for research or product improvement, we follow the principle of data minimization—collecting only what's necessary, for the specific purpose you've consented to, and only for the duration required.

Building a Movement, Not Just a Product

The wearable device industry has normalized deeply problematic data practices by burying them in legal documents and making them seem inevitable. At Cirdia, we're not just building another device with marginally better terms. We're reimagining what relationship between technology companies and users should look like—one founded on respect, transparency, and genuine partnership.

When our market research showed that women wanted "a fitness tracker that doesn't sell you out" and to "stay in their bodies, not on their phones," they weren't just expressing product preferences. They were articulating a vision for a fundamentally different relationship with technology—one that enhances their embodied experience rather than extracting value from it.

Join Us in Reimagining Wearable Privacy

Your intimate body data—your heartbeats, sleep patterns, stress levels, and activity—deserve better than becoming inputs for advertising algorithms or assets on corporate balance sheets.

At Cirdia, we're committed to proving that better approaches aren't just possible—they're essential for the future of ethical technology. Your data, like your body, should always remain yours to control.

Because wellness isn't about optimization or gamification. It's about presence, autonomy, and living fully in your body. And technology should serve that vision, not undermine it.

Mary Camacho is CEO and Co-founder of Cirdia, a Public Benefit Corporation reimagining ethical wellness technology. This post is part of our ongoing commitment to transparency about how we approach privacy and data governance.

In Colorado, I had built a rich wellness community without even realizing it. I ran with a close friend on the Cherry Creek trail 2-3 times a week, and even completed a 7k race together in the city. I had created and played on a soccer team called Optimists United in a women's league in the city—a team that gathered on weekends and created both fitness and an incredible sense of community. On weekends, I often went on long bike rides, exploring the beautiful Colorado landscape. I had friends that I trained for and completed triathlons with, pushing each other to reach new goals. These connections weren't just social—they were the invisible infrastructure supporting my physical and mental well-being.

I also had a network of physical therapists and trainers I could reliably return to whenever I needed support or guidance. They knew my history, understood my body's quirks and limitations, and could provide personalized advice based on our established relationship.

When I moved, my focus shifted almost entirely to work. I love what I do, and it was easy to pour my energy into building new technologies and organizations. But gradually, I noticed changes in myself. Without my running buddy on the Cherry Creek trail, runs became less frequent. Without Optimists United, the accountability and joy of weekend soccer disappeared. Without my triathlon friends, that motivating sense of shared challenge faded. Without my weekend cycling routine, my exploration of new places diminished.

This shift wasn't just about physical activity. It was about the absence of a community that valued and supported wellness as part of a balanced life. In Colorado, well-being wasn't something I had to actively remember or prioritize—it was woven into my social fabric, reinforced by shared activities and mutual accountability.

I've tried to recreate these connections virtually. During COVID lockdowns, I worked out over Zoom with Dana—one of my best friends and now a co-founder of Cirdia. As I shared in my previous post, I also attempted to establish a virtual fitness connection with my sister-in-law. While these efforts worked to some degree for a while, they weren't the same. The technology simply didn't support the depth of connection and accountability that my in-person wellness community had provided.

A Fitness Tracker That Doesn't Sell You Out

This experience taught me something crucial: wellness is inherently social and contextual. While tracking metrics can be helpful, the most powerful motivator is often the community around us—people who share our values, notice our patterns, and care about our well-being beyond just numbers on a screen.

I don't need technology that turns my health into a game, making me chase streaks and rings instead of actually feeling better. I don't need devices designed to keep me glued to an app rather than present in my body. And I certainly don't want my fitness tracker forcing me to store my private health data in the cloud—where it can be hacked, sold, or used against me.

What I want—what many of us want—is a fitness tracker that helps me maintain my health as I age, not one that pushes me to extremes. I want gentle prompts and check-ins, not nagging nudges or goal-shaming. I want tools that respect my natural rhythms and personal choices. I want a device designed for women, by women—one that helps me stay in my body, not on my phone.

This insight profoundly shapes how we're building Cirdia. We're not just creating devices that track metrics; we're building technology that respects both individual privacy and community connection. This means:

• A system where your data lives where it belongs: with you, not on some cloud server owned by a faceless company
• Community ownership through our public benefit corporation structure and path toward a hybrid retail cooperative
• Design that recognizes different needs throughout the day and night, adapting to your real life rather than forcing you to adapt to technology

Your Body Shouldn't Be For Sale

When I look at mainstream wellness technology today, I see a missed opportunity. The focus on individual metrics and competition overlooks the profound role that supportive communities play in sustainable well-being. Meanwhile, the extractive approach to personal health information undermines the trust essential for meaningful community connection.

Your steps. Your heart rate. Your sleep patterns. Your reproductive cycle. All uploaded. All stored. All potentially for sale.

At Cirdia, we're working to reconcile these contradictions—building technology that supports both personal control of your information and community connection, both private reflection and shared experience. Because wellness isn't just about optimizing personal metrics; it's about creating the conditions for wholeness and balance in our lives.

This journey is deeply personal for me. I hope to recreate the sense of community I once had—both locally where I live now and virtually with people I care about who live elsewhere. With Cirdia, we're creating the technology I wish had existed when I moved away from my wellness community—technology that truly enables connection across distances while respecting your right to control your most personal information.

By building better tools for sharing and connection that don't force you to give up ownership of your health data, we can create new kinds of wellness communities that transcend geographic limitations. Communities where we can support each other, celebrate progress together, and hold each other accountable—all while maintaining personal control over what we share and with whom.

That's the vision driving Cirdia forward: wellness technology that brings us together rather than reducing us to data points. Technology that helps you stay in your body, not on your phone. Because tracking your health should feel empowering—not invasive.

Like many people trying to stay fit, I'd been working with a personal trainer who used a specialized app to track my progress. Every session, every weight, every rep—I diligently entered it all. My fitness device synced with the app, creating a comprehensive picture of my fitness journey. I even uploaded progress photos, creating a visual timeline of my transformation.

The app became my fitness memory. I could look back and see how much I'd improved on my deadlifts over time, when I'd hit my personal bests, which exercises I struggled with consistently. It wasn't just data—it was a record of my hard work, my discipline, my progress.

The Day My Fitness History Vanished

Then came the moment when I felt ready to continue my fitness journey independently. I'd learned the patterns, understood my body better, and felt confident in designing my own workouts. It was a proud moment of growth—until I discovered the hidden cost.

When I stopped working with my trainer, I didn't just lose the ongoing support and expertise. I lost my entire fitness history. Every single workout I had manually entered, every achievement I had celebrated, every photo documenting my progress—all of it was either locked away on someone else's server or simply deleted.

Just like that, years of my fitness data had evaporated.

The loss was more than just inconvenient. Without my history, I had no reference points. How much weight had I been lifting for chest press? What was my record for split-squats? Which variations of exercises worked best for my body? I was essentially starting from scratch, my digital fitness memory wiped clean.

When Your Data Isn't Really Yours

That's when it really hit me: despite all the time I'd spent inputting this data, despite this being information about my body generated by my activities, I had no actual ownership of it. The app had never been designed for me to truly own my information—it was designed to keep me tethered to their ecosystem.

This experience wasn't isolated. Around the same time, I was looking for ways to stay connected with my sister-in-law—a sister of my heart, really—and a nurse who lived in a different part of the world. We wanted to find a way to work out together despite the distance, to motivate each other and share our fitness journeys.

I suggested we use a popular fitness wearable and platform that would let us share activities and cheer each other on remotely. Her response stopped me in my tracks: "I'd love to work out with you virtually, but I'm not comfortable with a company storing and selling my biometric data. Isn't there another way we could connect around fitness?"

Her concern wasn't paranoia—it was prescient. She understood something that had become painfully clear to me: our most intimate biological data has become just another commodity to be extracted, stored, and monetized by companies who see us primarily as data sources rather than people.

Heart rate, sleep patterns, workout history, stress levels, body temperature and even ovulation cycles—these aren't just numbers. They're deeply personal insights into our physical and mental health. They can reveal medical conditions, emotional states, and behavioral patterns. Yet the privacy policies governing this data are deliberately vague about how it's used, shared, and monetized.

The more I thought about it, the more I felt a fundamental disconnect between how personal this data is and how impersonally it's treated. This wasn't just a technical problem—it was an ethical one.

Building a Different Approach

That's a big part of why I started Cirdia. I wanted to create wellness technology built on a different foundation—one where your data stays on your device by default,and when you back it up, you back it up to your private data space. I wanted a system where sharing happens only when you explicitly choose it, and one that is designed to serve you rather than extract value from you.

With Cirdia, your data truly remains yours. Everything captured by your wearable or entered manually belongs to you and stays accessible to you—even if you decide to change how you use our system in the future. We don't hold your historical information hostage or suddenly make it inaccessible if your relationship with us changes. Your biometric history is exactly that: yours.

While we'll offer premium features through subscription (we are building software after all, and continuous development requires sustainable funding), we fundamentally reject the model where your own data becomes unusable unless you pay. The data you generate and input will always remain accessible and exportable, regardless of your subscription status.

Privacy isn't just a feature we've added—it's fundamental to how we've designed our entire system. Because your heartbeat, your sleep patterns, your workout history—they're not just data points. They're parts of your life, your health, your story. And we believe they should remain firmly in your control.

In my next post, I'll share how moving away from my wellness community in Colorado taught me about the critical role community plays in maintaining well-being, and how that insight shapes Cirdia's approach to community ownership.

For years, I've watched as our most intimate biological data has become just another commodity for Big Tech. Our wellness information—that most personal narrative of our bodily rhythms and patterns—has been extracted, stored in centralized servers, and used primarily to fuel consumer profiling and product development. All too often, when we want to access our own historical data, we're met with subscription paywalls. And when researchers seeking to advance public health try to access diverse wellness data, they find it locked away in corporate vaults, released only selectively when it serves business interests.

This reality has felt increasingly uncomfortable to me, especially as biometric data has become more sophisticated and intertwined with our identities. When Fitbit was absorbed by Google, completing Big Tech's consolidation of the wearables market into the hands of a few giants—Apple, Samsung, Huawei, Google—I knew the time had come to create an alternative.

A Vision Born from Personal Need

I'll be honest: I'm building for myself first. I want a device that fits my small wrist comfortably, that I can wear to work without it screaming "fitness tracker," and that gives me genuine agency over my own wellness data. I want to choose who I share that data with and how it's used. And I suspect I'm not alone.

The name "Cirdia" itself comes from "circadian"—the natural cycle of day and night that governs so much of our health and wellbeing. We're creating a system that acknowledges these natural rhythms with different devices for daytime activity and nighttime rest, because comfort and function shouldn't be compromised by one-size-fits-all design.

But Cirdia isn't just about creating better devices. It's about reimagining the entire relationship between people and their wellness data.

Privacy by Design, Community by Choice

At the core of Cirdia is a simple belief: your biometric data belongs to you. We're building wearables and applications that store and process your wellness data locally on your device. There are no centralized servers mining your information, no corporate algorithms profiling your habits.

When you choose to share—whether with health partners, research institutions, or friends for wellness challenges—that sharing happens directly, peer-to-peer. We're using Holochain's distributed architecture so that you control what's shared, with whom, and for what purpose. This isn't just about protecting privacy; it's about enabling community and connection on your terms.

A Journey We'll Take Together

What excites me most about Cirdia isn't just what we're building today, but how we're building it and where we're headed. We've incorporated as a Public Benefit Corporation because we believe wellness technology should serve the public good. Our roadmap includes not just product launches but a transition to community ownership through a hybrid retail cooperative model.

This isn't just another startup seeking rapid growth and acquisition. This is a movement to reclaim our wellness data, to build technology that serves humans first, and to prove that community and privacy can coexist harmoniously.

From our initial community building to our upcoming Kickstarter, from equity crowdfunding that allows our users to become owners to our eventual exit to community—every step of this journey is designed to expand the circle of stakeholders who shape what Cirdia becomes.

An Invitation to Join Us

I've had conversations with people spanning from their 20s to their 80s about Cirdia, and I've been struck by how the desire for greater agency over personal data transcends age, gender, and technical background. An 80-year-old woman eagerly asked to join our beta testing. Young privacy advocates immediately understood the value. Wellness professionals saw the potential for more ethical practice.

This tells me we're onto something important—something that speaks to a fundamental human desire for autonomy and connection.

As we launch our website and begin our community journey, I invite you to take the next step with us:

1. Sign up for our newsletter at cirdia.com to receive updates about what we are building from the team as well as community curated articles… and also to be among the first to find out about our Kickstarter launch.
2. Join the conversation on LinkedIn, Instagram, and Bluesky to share your thoughts on privacy in wellness technology.
3. Share your wellness journey with the hashtag #MyCirdiaMoment to be featured in our community stories.
4. Stay tuned for focus group opportunities where you can directly influence our product development.

Because ultimately, while I may have started this journey from personal need, Cirdia will grow into what we collectively want and need it to be. This is just the beginning of creating a future where privacy and community coexist harmoniously in wellness technology.
