3. Local Storage

The App uses local device storage to save solo puzzles, preferences, and the demo start date. This data is not sent to the developer. Deleting the App may remove it.

4. Game Center

Online Duel and global leaderboards use Apple's Game Center. The App sends puzzle data, progress counts, match results, and completion times through GameKit and displays matched players' Game Center names.

5. Purchases and RevenueCat

Lifetime Access is purchased through Apple's App Store. The App uses RevenueCat to retrieve product information, validate whether the lifetime entitlement is active, and provide purchase reporting. RevenueCat may process an anonymous app user identifier, purchase receipts or transaction information, product identifiers, entitlement status, device and app version information, and related diagnostic data needed to provide purchase services. The developer does not receive your full payment-card details.

6. Third-Party Services

The App contains no third-party analytics or advertising SDKs. Game Center provides online gameplay, and RevenueCat provides purchase and entitlement management.
