YOUR DATA STAYS YOURS
Penwise is local-first and server-less for health data. Everything you log lives in an encrypted database on your device. The only cloud copy is an encrypted backup in your own Google Drive - we never see it and hold no keys. No health data on our servers, no ad-network sharing, no selling your data.

SWITCHING FROM SHOTSY?
Import your Shotsy export (CSV or backup) in a couple of taps and continue where you left off.

PRICING
- Free core tracker, forever
- Penwise+: 2.49 EUR per month, 19.99 EUR per year, or 59.99 EUR lifetime, after a 14-day free trial

Penwise is a tracking and education tool. It is not a medical device and does not provide medical advice, diagnosis or treatment. Always follow your clinician's guidance.
