Data We Process

The apps are vocabulary learning apps. They store study progress and settings on the user's device so the app can show review state and continue study sessions.

The apps do not use app login accounts.

The apps use RevenueCat and the platform store billing systems to process lifetime access. Purchases are handled by Google Play or Apple App Store, and entitlement status is checked through RevenueCat. The apps do not collect payment card numbers.

Use Of Data

Study progress and settings are used to provide app functionality. Purchase entitlement information is used to unlock premium access and restore purchases.

Sharing

Purchase and entitlement data may be processed by Google Play, Apple App Store, and RevenueCat for billing, entitlement verification, customer-center functionality, and purchase restore functionality.

Retention And Deletion

Local study progress remains on the user's device unless the app is deleted, app data is cleared, or the in-app reset function is used. Purchase records are handled by the relevant app store and RevenueCat according to their own retention policies.

Security

The apps use platform billing services for purchases. Network connections to store and entitlement services use HTTPS.
