2. Scope

This statement applies to the sudøku mobile app and to public app-store pages that reference it.

3. Privacy at a Glance

• No account, user profile, or login is required.
• Puzzles, game progress, statistics, and settings are handled primarily on your device.
• No custom backend is used to synchronize gameplay data.
• The current app does not integrate an analytics SDK or crash-reporting SDK.
• The ad-supported version uses Google AdMob. Ad requests are configured as non-personalized, but Google may still process technical data required to provide, secure, measure, and comply with advertising services.
• Apple or Google process purchase information when you make or restore an in-app purchase.

4. Data Stored on Your Device

For app functionality, sudøku may store locally:

• current puzzle state, progress, notes, hints, timer values, and mistake counters;
• statistics such as games played, wins, best times, and recent history;
• language, appearance, and gameplay settings;
• limited premium-entitlement or purchase-restore state.

This gameplay data is not uploaded to a Jetzt & Dahanna server because the app has no gameplay backend.

5. Third-Party Processing

Google AdMob

Where ads are enabled, the app uses Google AdMob and requests non-personalized ads. Google may process information such as IP address, device and app information, advertising or other device identifiers where available and permitted, ad interactions, and diagnostics. The exact processing depends on your device, platform, region, consent choices, and Google's services.

Apple App Store / Google Play

Purchases and restores are handled by Apple or Google. They process transaction and store-account information under their own policies. We do not receive your payment-card details.

In-app review

The app may invoke the platform's Apple or Google review-prompt system. Any processing by the store platform is governed by that provider.

6. Purposes and Legal Bases

Where GDPR, UK GDPR, or similar law applies, processing may be based on performance of a contract (providing requested app and purchase functionality), legitimate interests (security, fraud/abuse prevention, and reliable operation), consent where required for advertising-related processing, and legal obligations.

7. Sharing

We do not sell personal information. Data may be processed by Apple, Google, and Google AdMob where the corresponding feature is used, or disclosed where required by law. Because core gameplay data remains local, it is not routinely shared with us.

8. Advertising

The free/ad-supported version may display ads through Google AdMob. Requests from sudøku are configured as non-personalized. “Non-personalized” does not mean that no data is processed: technical data may still be used by Google to deliver and measure ads, prevent fraud, and meet legal requirements.

9. In-App Purchases

Purchases are handled through Apple App Store or Google Play. sudøku stores only the limited state needed to recognize or restore premium access. Billing details are not available to us.

10. Retention and Deletion

Local app data remains on your device until it is reset or removed, for example by using available reset functions, clearing app data, or uninstalling the app. Device or cloud backups controlled by your operating system may retain or restore app data according to your backup settings. Third-party providers retain data according to their own policies.

11. International Transfers

Apple and Google may process data outside your country. Any international transfers are governed by the safeguards and terms of the relevant provider.

12. Security

We use reasonable technical and organizational measures appropriate to the app. No storage or transmission method can be guaranteed to be completely secure. Because core data is local, the security of your device and backups is also relevant.

13. Children

sudøku is a general-audience puzzle app and is not specifically directed at children. Where consent is legally required for a child to use advertising-related services, the applicable platform/provider rules and consent requirements apply. If you believe personal data relating to a child has been processed improperly, please contact us.

14. Your Rights

Depending on your location, you may have rights of access, rectification, erasure, restriction, objection, portability, withdrawal of consent, and complaint to a supervisory authority. For gameplay data stored only on your device, we generally cannot access or delete it remotely; you can manage it on the device. Requests concerning data processed by Apple or Google may also need to be directed to the relevant provider.

15. Third-Party Privacy Information

• Apple Privacy Policy

16. Changes

We may update this statement when the app, providers, or legal requirements change. The current version will remain published at this URL so existing app versions continue to reach it.
