Habit Tracker

01 What information is involved?

At a glance, what the app touches and where it ends up:

02 Account (optional)

You can use the app as a guest without an account. If you sign in, authentication is provided by Supabase using your email and password.

Supabase handles authentication and stores your data in a database protected by row-level security, so each record can only be read by the account it belongs to. Passwords are hashed by Supabase and never stored by the app.

03 What we store

As a guest, your habits (name, color, icon, check-in days and archive date) stay on this device. When you sign in, they are stored in Supabase and tied to your account; habits created as a guest are merged into your account the first time you sign in and then removed from local storage.

Preferences (language, theme and biometric unlock) stay on the device.

04 Backups

Export creates a JSON file with your habits and hands it to the share sheet, so it goes only where you choose to save or send it. Import reads a file you pick and never uploads it anywhere else.

05 Biometric unlock

You can optionally lock the app with Face ID, Touch ID or your fingerprint. Your operating system checks your biometrics; the app never sees or stores them and only remembers whether the lock is turned on.

06 Deleting your data

Signing out removes your session from this device. To delete your account and the habits synced with it, email us from the address you signed up with and we will remove it from Supabase.

Preferences stored on the device are deleted when you uninstall the app or clear its storage.

07 Third-party services

The About section of the settings page loads the developer's profile photo from GitHub, and links such as Rate on Google Play open in your browser or store app. Those services may log your request (for example your IP address) under their own privacy policies.

The app does not include third-party analytics, tracking or advertising software, and we do not sell or share your personal information.

08 Changes to this policy

This policy may be updated as the app changes. The effective date at the top shows the latest revision, and continuing to use the app after changes means you accept the updated policy.
