Privacy Policy for Sudoku Sigma

Last updated: May 9, 2026

This Privacy Policy explains how Sudoku Sigma ("the App") handles your information.


1. Information We Collect

The App itself does not collect, store, or transmit any personal information. All game data (settings, saved games, statistics) is stored locally on your device only and never sent to any server.


2. Third-Party Advertising (Google AdMob)

The App displays ads served by Google AdMob. To serve and measure ads, Google may collect the following on our behalf:

This data is collected and processed by Google under their own Privacy Policy: https://policies.google.com/privacy

On iOS, the App requests your permission before allowing any tracking via Apple's App Tracking Transparency (ATT) framework. You may deny this permission at any time in your device Settings → Privacy & Security → Tracking.

In the European Economic Area (EEA) and the United Kingdom, the App presents a GDPR consent form before showing ads. You may withdraw or change your consent at any time by restarting the App.


3. Children's Privacy

The App does not knowingly collect any personal information from children under the age of 13. If you believe a child has provided personal information through the App, please contact us so we can take appropriate action.


4. Data Retention

Since the App stores all data locally on your device, you can delete all data at any time by uninstalling the App. We do not retain any personal data on our servers because no data is ever sent to us.


5. Changes to This Policy

We may update this Privacy Policy from time to time. Changes will be reflected by updating the "Last updated" date above. Continued use of the App after any changes constitutes acceptance of the updated policy.
