Privacy Policy

This Privacy Policy applies to the Sudoku Dojo app. This service is provided at no cost, is completely ad-free, and is intended for use "as is."

This page is used to inform users regarding policies with the collection, use, and disclosure of information for anyone who decides to use this Service. By choosing to use our Service, you agree to the collection and use of information in relation to this policy.

Information Collection and Use

We respect your privacy. Sudoku Dojo does not require you to create an account, and we do not request or collect any personally identifiable information (such as your name, address, or email address) for the core functionality of the game.

To improve the app and make the game better for you, we collect anonymous, aggregated usage data. This includes game-specific statistics such as puzzles completed, hints used, and general interactions within the app.

Optional Google Play Games Services

Our app offers integration with Google Play Games Services to provide features like leaderboards and achievements. This feature is completely opt-in. If you choose to enable these services, you will sign in using your Google account.

We do not store your Google account information, email, or personal identity on any external servers. Your authentication and any game progress associated with this profile are managed directly by Google. You can revoke this access at any time through your Google account settings.

The app uses third-party services that may collect anonymized data to help us understand how the app is used and to track errors. The third-party service providers used by the app include:

Log Data and Crash Reporting

Whenever you use our Service, in the case of an error or crash in the app, we collect data and information on your phone called Log Data (through Firebase Crashlytics). This Log Data helps us find and fix bugs. It may include information such as your device Internet Protocol (“IP”) address, device name, operating system version, the configuration of the app when the crash occurred, the time and date of the crash, and other related statistics. All of this data is anonymous.

Links to Other Sites

This Service may contain links to other sites. If you click on a third-party link, you will be directed to that site. Note that these external sites are not operated by us. Therefore, we strongly advise you to review the Privacy Policy of these websites. We have no control over and assume no responsibility for the content, privacy policies, or practices of any third-party sites or services.

Children’s Privacy

Our app does not target anyone under the age of 13. Because we do not collect any personally identifiable information from any of our users, we do not possess any personal data concerning children. All usage and crash data collected is completely anonymous and aggregated, meaning we cannot identify individual users or their age. If you are a parent or guardian and have questions about your child's use of the app, please contact us.

Changes to This Privacy Policy

We may update our Privacy Policy from time to time. You are advised to review this page periodically for any changes. We will notify you of any changes by posting the new Privacy Policy on this page. These changes are effective immediately after they are posted.
