Sudoku World is a fantasy-themed Sudoku game for Android, with Web builds used mainly for testing and development workflows. This Privacy Policy explains what information is processed when you use the app, how that information is used, and what choices you have.
The app does not require you to create an account and does not operate its own gameplay backend for player profiles or cloud saves. Most gameplay data is stored locally on your device. Some information may be processed by third-party platform and monetization services, especially Google AdMob and Google Play.
Sudoku World stores gameplay and preference data locally to make the app work as expected. Depending on the features you use, this may include:
This local data stays on your device unless you remove it by clearing app storage or uninstalling the app.
Sudoku World uses Google AdMob to load and show ads. In the current product design, this includes post-game ads and optional rewarded ads that can grant an extra hint.
When AdMob is used, Google and its partners may collect or receive information such as:
AdMob data processing is governed by Google’s own privacy terms and policies.
On supported Android release builds, Sudoku World uses Google Play Billing for the Remove Ads purchase and purchase restore flow.
When you make or restore a purchase, Google Play may process information such as:
Sudoku World stores only the local entitlement state needed to reflect whether Remove Ads is active or pending on your device. Payment processing is handled by Google Play, not by the app itself.
If you enable notifications, Sudoku World may schedule local reminders on your device to encourage you to return to the game after inactivity.
For this feature, the app may process:
Sudoku World does not require its own remote push-notification backend for this feature. On Android, scheduled local reminders may remain scheduled across device restart or app update until they are shown, replaced, cancelled, disabled, or removed with the app’s data.
Sudoku World does not currently require direct account registration, username creation, or an in-app profile. The app also does not include a dedicated first-party analytics backend in this repository.
That said, third-party services such as Google AdMob and Google Play may process information under their own policies when you use monetization features.
We use the information described above to:
Information may be shared or made available to third parties only as needed to operate the app features you use, including:
If required by law, information may also be disclosed to comply with legal obligations, enforce rights, or protect users and the app.
You can control or limit data processing in several ways:
If you are a parent or guardian and believe a child has used the app in a way that raises privacy concerns, use the developer contact information provided in the app store listing or official distribution page.
Third-party providers used by Sudoku World, including Google, may process information on servers located outside your country. Those providers are responsible for handling international data transfers under their own legal and contractual frameworks.
For more information about how third-party services process data, review their policies directly:
This Privacy Policy may be updated from time to time to reflect product, legal, or platform changes. When the policy changes, the effective date at the top of this document will be updated.
For privacy questions, requests, or concerns about Sudoku World, use the developer contact details shown in the app’s store listing or official distribution page. If this policy is published on a website or another external page, the same direct contact details should be published alongside it.
