Walrus 🦭/acc (@WalrusProtocol): Your wearable knows everything about you. Who else does?

Your wearable knows everything about you. Who else does? Every day, millions of consumers click into an app and browse the data collected by their wearable devices. From sleep quality to activity levels and even location, consumer wearables generate an overwhelming amount of data from the almost 1 in 3 Americans that use one. All of this adds up to a remarkable amount of personal information — information most people wouldn’t share willingly with a total stranger. But where does all that data actually go once it leaves your device? Spoiler: It's sitting on someone else's servers The answer is simpler than you might think. For most wearables, data goes onto a centralized database: typically cloud servers hosted by AWS, Google Cloud, or Microsoft Azure. So every time you sync your device and update data, you’re trusting not only that the maker of the wearable will protect your data, but also that the storage solution they’re using will do the same. Which isn’t always the case — In 2021, an unsecured third party database exposed more than 61 million records from Fitbit and Apple users. And get this: there are basically no regulations like HIPAA protecting wearable data. Your fitness tracker info is actually LESS secure than your medical records. That’s a lot of blind trust. Where things get weird The Oura Ring situation is a perfect example. Oura has sold 5.5+ million smart rings, and in 2025 they announced a new manufacturing deal to supply the Department of Defense. Buried in the announcement? A mention that DoD data would be hosted on Palantir - a controversial surveillance tech company. Users freaked out (understandably). Was Oura selling everyone's data to Palantir? Could the government access your sleep patterns? Oura clarified that only DoD partnership data goes to Palantir, not regular user data. But the damage was done - people realized they had no actual control over where their data lives. Then there's 23andMe, the genetic testing company that filed for bankruptcy in early 2025. Whoever buys the company gets all their customers' DNA data. It’s a scary prospect if you were counting on a privacy policy to protect you. But there’s a better way Here's how it should be: your health data should belong to you. Full stop. @CudisWellness is doing something different with their longevity platform and CUDIS Ring. Instead of dumping everything onto centralized servers, they use Walrus to encrypt your data and spread it across multiple computers worldwide. No single company controls it. No one can sell it without your permission. It can't become a bankruptcy asset. But here's where it gets interesting: when you own your data, you can monetize it. Want to sell it to researchers studying heart disease? Go for it. AI company needs training data? Name your price. Your data, your choice. Making your data yours again For too long, we’ve decided that data can only be stored one way: on centralized servers owned by big tech companies, governed by privacy policies that offer no transparency. But we have better options now. You can own your health data. Privacy can be the default, not just a promise. Your wearable knows everything about you. It's time for you to decide what happens with that information.
