Data we collect
Jamchik does not require registration, login, a name, an email address, or a phone number. The current app does not send your answers or learning history to a Jamchik server.
Data stored on your device
Learning progress, task history, streaks, XP, gems, settings, locally generated diagnostics, cosmetics, and nicknames are stored on your device. You can export a backup from Settings. If you delete the app or clear its storage without a backup, this data may be permanently lost.
Analytics, advertising, and tracking
The current version contains no third-party advertising SDK, no behavioral advertising, and no cross-app tracking. Gameplay events and error diagnostics used by the app remain local and can be included in a backup that you choose to export.
Notifications
If you allow notifications, Jamchik may schedule learning reminders locally through your operating system. You can change notification permission in your device settings at any time.
Third-party platforms
Apple may process information when you download or update Jamchik through the App Store under Apple's own privacy policy. Jamchik does not receive your Apple Account credentials or payment information.
Children
Jamchik is intended for users aged 13 and older. We do not knowingly collect personal information from children under 13. If you believe personal information was provided to us, contact us so we can investigate.
