1. Information We Collect
WordPecker Plus ("the App") does not collect any personally identifiable information (name, email, phone number, location, etc.).
Learning data (answer history, accuracy, streaks, mastered-word count, purchase state) is stored only on your device (AsyncStorage) and is never transmitted to our servers.
The App requires no account or sign-in.
2. Purchase Information
Unlocking additional content is processed through Google Play Billing and RevenueCat.
Payments are handled by Google and RevenueCat; we never receive your card or payment details.
RevenueCat processes an anonymous purchase identifier to verify and restore purchases. See:
English: The App has no accounts, and learning data is stored only on your device. To delete your data, (1) uninstall the App, or (2) go to device Settings → Apps → WordPecker Plus → Clear storage. Either action permanently removes all on-device learning data. Because we store no user data on any server, no deletion request is necessary.
削除後、データの復元はできません。/ Deleted data cannot be recovered.
