App data
Best results, current batch and sound settings stay in a local file. Touch and available hinge readings are processed on the device. No camera, microphone, photos, account, recording or export is used.
Advertising and choices
Advertising uses Google Mobile Ads and consent management. For ad delivery, measurement and improvement, the SDK may collect IP addresses (which may estimate general location), device or advertising identifiers, crash and performance data, ads viewed and product interactions. See Google's data disclosure and Google's Privacy Policy.
Regional consent is checked before ad initialization. Tracking follows your system permission, and you can play without granting it. Personalization is restricted when the necessary consent or tracking permission is absent; this does not eliminate all ad SDK data processing. Revisit consent through the app's advertising privacy options when required, and change tracking permission in system settings. A verified ad-removal purchase stops ad requests. Google manages its retention, deletion and international processing under its policies.
Purchases
StoreKit contacts Apple for products, purchases and restoration. The app uses verified purchase entitlements. The developer does not receive card numbers or payment details. Apple manages transaction records and refunds.
Storage and deletion
To remove local settings and records, delete the app from your device. Keychain credentials, shared copies, device backups and provider records may require separate management.
Public pages and support
