We believe in full transparency about how your data is handled — which in our case, is barely at all.
This Privacy Policy explains how Mobile Dev Academy ("we", "us", "our") handles information when you use SudokuX. We are committed to protecting your privacy — and the simplest way we do that is by collecting as little data as possible.
SudokuX is an offline puzzle game. We do not require account registration or any personal information to use the app.
The only data stored remains on your device and includes:
We do not collect:
All locally stored data is used exclusively to:
This data never leaves your device and is never transmitted to us or any third party.
SudokuX does not integrate any third-party analytics, advertising SDKs, or crash-reporting services in its current version.
The app is distributed via Google Play. Google may collect certain technical and usage information as part of operating the Play Store platform. Please refer to Google's Privacy Policy for details.
SudokuX is suitable for all ages, including children under 13. Because we collect no personal information whatsoever, the app is fully compliant with the Children's Online Privacy Protection Act (COPPA) and Google Play's Families Policy.
We do not knowingly collect, use, or share personal data from children or anyone else. Parents and guardians can let their children use this app with confidence.
Since all data is stored locally on your device using Android's standard SharedPreferences and internal storage, its security depends on your device's own security settings (screen lock, encryption, etc.).
We recommend keeping your device's operating system up to date and using a strong screen lock for your own security.
Game data is stored on your device for as long as the app is installed. You can delete all app data at any time by:
Since we hold no data on our servers, there is nothing to request deletion of on our end.
Because we collect no personal data, standard rights such as data access, portability, or erasure requests are inherently satisfied — there is simply no personal data of yours held by us to access, transfer, or delete.
If you have any questions about your data, you are always welcome to contact us.
We may update this Privacy Policy from time to time. When we do, we will revise the "Effective Date" at the top of this page and, where appropriate, notify users through an in-app notice or Google Play update notes.
We encourage you to review this policy periodically. Continued use of the app after changes constitutes acceptance of the updated policy.
