FAQ

Do you collect or store my health data?

No. Your weight entries, fasting sessions, and settings never leave your device. We have no server and no access to your data.

Can I delete my data?

Yes. Tap any weight or fasting entry to edit or delete it. Since all data is stored only on your device, deleting the app also removes everything.
