Data & privacy
Effective September 3, 2026
A plain-language summary of what Bai Ze stores and how you control it. Bai Ze is a personal project, not a company. The Privacy Policy is the full legal notice — this page is the short version.
How this relates to the Privacy Policy
Use this page for a quick map of device vs cloud storage and controls.
For the complete legal statement, see the Privacy Policy at https://bebaize.com/privacy (also linked as Privacy Policy in the app).
Stored on your device
Reading progress, highlights, preferences (theme, font size, reminders), and similar state can live locally so the app works between visits.
Signing out clears the local session. Some on-device files may remain until you uninstall the app.
Stored in the cloud (when you are signed in)
Your account id and email (from email sign-up or Google).
Learning state we sync: progress, highlights, streaks, collections, mindscape scores, focus aspects, cache items, and related settings.
Host: Supabase (database and auth). Region depends on the current project configuration.
Processors
Google — optional Google sign-in.
Supabase — auth (email/password and Google) and synced data.
RevenueCat — subscription status.
Apple / Google Play — store billing.
Expo — hosting, updates, and diagnostics.
These are tools the individual operator uses to run the app — not a corporate affiliate network.
What we do not do
We do not sell your personal information.
We do not use notification permission or reading data for ads.
Export and delete
Profile → Export my data downloads a copy of learning data we can export from the app.
Profile → Delete account data removes synced cloud learning data we store for your user id.
For a full account deletion request, email privacy@bebaize.com from the same address you use to sign in.
Notifications
Reading reminders are optional. You can disable them in Profile.
