Geography — World Literacy App ("Geography", "we", "us") is published by SupportU, LLC. This policy describes how we handle your information.
Account data. If you sign in with Apple, we receive a stable user identifier, and optionally your name and email (if you choose to share them). We store these in our Supabase-hosted database to sync your progress across devices.
Learning progress. Your session history, knowledge levels, and familiarity scores are stored locally on your device in SQLite and optionally synced to our servers via iCloud or Supabase.
Device information. We collect anonymous device type and OS version for crash diagnostics. We do not collect advertising identifiers.
Purchase data. Subscription status is managed by RevenueCat. We receive entitlement status but never see your payment details — Apple processes all transactions.
We do not sell your data. We share data only with:
Your data is stored on Supabase infrastructure with row-level security enabled. Local data is stored in an encrypted SQLite database on your device. Sensitive credentials are stored in the iOS Keychain via expo-secure-store.
You can request deletion of your account and all associated data by contacting us at geography@supportu.ai. You can also use the app in anonymous mode without creating an account.
Geography is not directed at children under 13. We do not knowingly collect personal information from children.
We may update this policy from time to time. Material changes will be communicated through the app.
