Logic Puzzles · Privacy information

Game data stays on your device

The app does not require a user account. Quiz progress, answers, favorites, personal notes, language and reading preferences are stored locally. The developer does not receive this game data. There is no developer-operated cloud synchronization.

When you export a text backup or copy information, you decide where it goes. The app reads the clipboard for a backup only when you choose to import it. Keep exported backups private if they contain personal notes.

Purchases

The app uses Apple in-app purchases through Unity IAP to unlock its full version and restore ownership. Apple processes payment and provides transaction and entitlement information to the app. The app stores a local entitlement state to allow offline access.

We do not receive your payment card information or Apple Account password, and the app does not send receipts to a developer-operated server. Apple's handling of store transactions is covered by Apple's privacy policy.

Advertising and permissions

This version has no third-party advertising, behavioral analytics, tracking or generative AI service. It does not request access to your location, contacts, camera or microphone.

Apple may process diagnostics according to your device privacy settings. Such operating-system services are governed by Apple's policies.

Support and website

If you voluntarily email support, we receive your email address, message and any files you choose to attach. We use them to respond and resolve the issue, and retain them only as needed for support and any applicable recordkeeping obligations. You may request deletion by contacting us.

The website has no advertising cookies, sign-in or tracking scripts added by us. Hosting and email providers may process ordinary connection and service data to deliver these services. External links, including the App Store and Apple support, follow their own privacy policies.

Your choices

You can clear quiz data in Settings, delete the app's local data by removing the app, and delete any backups you exported. Device backups may retain copies under the backup service's settings. Clearing quiz progress does not erase Apple's purchase history or cancel ownership.

We do not knowingly collect children's personal information through the game. If a child sends personal information to support, contact us to request its deletion.
