Terms of Use
Last updated: 2026-05-08
These Terms of Use govern your use of the Sudoku app.
Daily Sudoku is operated by Jonathan Reis SDE LTDA under the Sunstone Apps brand.
Acceptance
By using Sudoku, you agree to these Terms of Use and the Privacy Policy. If you do not agree, do not use the app.
Use of the app
Sudoku is a puzzle game for entertainment. You can play games, save local progress, mark favorites, track statistics, and participate in the Daily Challenge available on the device.
You agree not to:
- interfere with the operation of the app, ads, analytics, or crash reporting;
- use reverse engineering, abusive automation, or unauthorized means to manipulate results;
- use the app in an illegal, fraudulent, or harmful way.
Local data
The app saves progress, settings, favorites, statistics, and history locally on the device. This data can be deleted in Settings, by uninstalling the app, or by clearing app data. In the first store release, the app does not provide accounts, cloud backup, or cross-device sync.
Ads and consent
Sudoku may show ads. The app uses Google AdMob and consent controls where applicable. Ad availability, format, and frequency may change to keep the app free and operational.
Purchases and paid features
The current app does not offer in-app purchases, subscriptions, paid coins, or restore purchases. If these features are added in the future, these terms and the store listing should be updated.
Intellectual property
The app, interface, code, brand, text, visual elements, and product logic belong to their respective owners. These terms only grant a personal, limited, revocable, non-exclusive license to use the app as provided.
Third-party services
The app may depend on third-party services, such as Google AdMob, Firebase Analytics, and Sentry. These services may have their own terms and policies.
Availability and changes
The app is provided as is. We may fix bugs, change features, remove functionality, adjust ads, or stop support when needed. We make reasonable efforts to keep the app stable, but we do not guarantee continuous operation, absence of errors, or compatibility with every device.
Limitation of liability
To the maximum extent permitted by law, the app operator will not be liable for indirect, incidental, special, punitive, or consequential losses related to the use or inability to use the app.
Termination
We may restrict or terminate access to the app if there is misuse, violation of these terms, or a legal requirement.
