Mahj Trainer works without an account. Practice progress, streaks, review history, onboarding choices, and preferences are stored locally on your device.
Apple processes Mahj Trainer Pro purchases. RevenueCat verifies entitlement status and may process an anonymous app user ID, transaction and entitlement information, and limited technical app or device context. It does not receive your practice content, name, or email. See RevenueCat's privacy policy.
No account, advertising identifier, analytics SDK, tracking pixel, location, contacts, photos, microphone, or health data. We do not sell personal information.
Local practice data remains until you delete it or remove the app. Apple and RevenueCat retain transaction records as needed to process and restore purchases. Support messages contain whatever you choose to send and are used to answer your request.
Mahj Trainer is not directed at children under 13 and does not knowingly collect personal information from children. We may update this policy when the app or its services change.
