BioState is built to be a "Zero-Knowledge" app. Your health data is yours alone. We do not operate servers, we do not require accounts, and we never see your fasting data.
Local Only: Every fasting log, mood rating, and note is stored exclusively on your iPhone’s secure local storage (UserDefaults). If you delete the app, your data is deleted with it.
No Identity Tracking: We do not collect names, emails, or device identifiers. You remain 100% anonymous while using the app.
We may collect anonymous crash reports to help improve the app's stability. This data contains no personal health information and cannot be linked back to you.
