Last updated: May 13, 2026

This Privacy Policy applies to all apps published by Nastech, including SudoZen - Calm Sudoku. We are committed to protecting your privacy and being transparent about how data is handled.

1. Information We Collect

Our apps do not directly collect personal information. However, third-party services used within the app may collect data:

2. App Tracking Transparency (iOS)

On iOS 14.5 and later, we request permission to track your activity via the App Tracking Transparency (ATT) prompt. If you decline, only non-personalized ads will be shown. You can change this at any time in Settings > Privacy > Tracking.

3. Data Storage

Game progress, settings, and statistics are stored locally on your device only. We do not operate servers that store your personal data.

4. Children's Privacy

Our apps are not directed at children under 13. We do not knowingly collect personal information from children.

5. Third-Party Links

Our apps may contain links to third-party services, such as the App Store or Google Play. We are not responsible for the privacy practices of those services.

6. Changes to This Policy

We may update this policy occasionally. Changes will be posted on this page with an updated date. Continued use of the app after changes constitutes acceptance of the new policy.
