Privacy Policy

1. Information we process

The app does not require account registration. It creates an anonymous user identifier for each installation. To provide the service, we process:

• Anonymous user and installation identifiers
• Operating system, device type, app version, and display language
• Answers, progress, incorrect-answer history, review history, and saved questions
• Purchased products, purchase status, and transaction identifiers needed to restore access

2. How we use information

We use this information to provide learning features, save progress, verify and restore purchases, resolve technical issues, and maintain security. We do not use it for advertising tracking or sell personal information.

3. Third-party services

In-app purchases are processed through Apple's App Store and RevenueCat. Purchase-related information is handled under their respective privacy policies. The app does not receive your Apple Account password or payment method.

4. Data retention and deletion

Learning data is retained for as long as needed to provide the service. You can delete learning data associated with the current JLPT app from Settings. Deleted learning data cannot be recovered.

Deleting learning data does not delete Apple's purchase history, cancel a purchase, or issue a refund. Apple and the purchase-management service may retain purchase records to restore access or meet legal requirements.

5. Security

We use reasonable safeguards, including encrypted communications, secure on-device token storage, and signed media URLs.

6. Changes to this policy

We may update this policy when features or legal requirements change. Material changes will be announced on this page or in the app.
