Albi is a privacy-first health tracker that keeps all of your data on your device. No accounts, no cloud sync, no tracking, no ads.

Track the health metrics that matter to you:
- Weight, in kilograms, pounds, or stones
- Blood pressure (systolic/diastolic) with automatic category guidance
- Resting heart rate, on its own or alongside a blood pressure reading
- Mood, to spot patterns over time
- Waist measurement and waist-to-height ratio for visceral fat awareness

See your progress:
- Clear, interactive charts for weight, blood pressure and heart rate, mood, and waist trends
- Blood pressure and heart rate shown together so you can see the full picture
- Recent readings and a health summary on the home screen

Your data, your control:
- Everything is stored locally on your device
- Optional on-device encryption to protect your health data
- Optional biometric app lock (fingerprint/face) with lockout after repeated failed attempts
- Back up and restore your data as a local file, or export to CSV for your own analysis
- Gentle reminders so your backups don't fall behind

Private by design:
- No account or sign-up required
- No cloud services
- No analytics or tracking
- Fully open source

Albi is built for people who want a simple, honest health diary without handing their personal data to anyone. Your health information stays with you.
