Show HN: FitmMetr – A privacy-first health tracker built by a CSO

I'm a cyber security and mobile forensics expert from Berlin, with a background working in KRITIS (critical infrastructure security) in Germany. Over the years, I’ve seen how often health and personal data is mishandled or sold.

I’ve also personally struggled to track my health data (weight, blood pressure, calories). I tried spreadsheets and various apps, but always stopped because they felt clunky and I didn’t trust where my data was going.

That’s why I built FitmMetr — a simple, privacy-focused health tracker:

Hosted securely in a German datacenter

Strongly encrypted data

No ads, no data selling, no hidden analytics

You can calculate your BMI, calorie needs, and track all your health data in one intuitive place.

It’s free for now — I’m looking for feedback and to see if people actually find this useful before adding more advanced features.
