I wear an Apple Watch. Have for years. It tracks my steps, my heart rate, my sleep, my workouts. I check it probably fifty times a day.
What I didn't think about for the longest time is where all that data goes. It sits on Apple's servers. They have my heart rate patterns going back years. My sleep data. My location history. Every walk I've taken, every workout I've logged.
And I have no idea what they're doing with it. Probably aggregating it, selling insights to researchers, maybe sharing it with advertisers. The terms of service are vague enough that they could be doing almost anything.
That bothers me now in a way it didn't before. Because health data isn't just data. It's your body. Your biology. The most personal information you can possibly generate.
That's why I'm building HashHeal at v03.
Why health data is different
When you post a photo on Instagram, that's one thing. When you share your heart rate variability, your sleep patterns, your stress levels — that's something else entirely.
Health data can be used against you. Insurers can adjust your rates. Employers can make decisions. Future you might be denied coverage because past you had patterns that suggested risk.
And unlike a social media post, you can't delete health data. Your DNA doesn't change. Your medical history is permanent.
Right now, most of that data is controlled by companies whose business model is extracting value from information. That's not a good setup.
What HashHeal does
HashHeal is a protocol I'm building at v03 to flip the script. Instead of your health data flowing to Apple or Fitbit or whoever, it stays with you. Encrypted. Private. Under your control.
If you want to share it with your doctor, you grant them access. If a researcher wants to use it, they request it and you decide. If an insurer wants to see it, you can tell them no.
The default isn't "your data belongs to the platform." It's "your data belongs to you, period."
I'm integrating this with Carbide so your health metrics can flow into your personal vault. All encrypted. All private. All yours.
Why this matters
I think health data is going to become incredibly valuable in the next decade. AI-driven diagnostics, personalized medicine, predictive health — all of it depends on having detailed information about your body.
If we don't own that data now, we're setting ourselves up for a future where our bodies are effectively owned by whoever has the data about them.
At v03, I'm trying to build systems where you control your health data the same way you should control any other data you create. Because if you can't own the data your own body generates, what can you own?
