Data We Do NOT Collect

Purchases

Sudoku Pro is an optional auto-renewing subscription. It is bought and managed by Apple (App Store) or Google (Google Play) through your account with them. The store tells the app whether you have an active subscription; we never see your name, email address or payment details.

Leaderboards and Achievements

If you're signed in to Game Center (Apple) or Google Play Games (Google), your daily solve times and achievements are sent to that service under your account with them, and other players may see your scores. The app sends nothing else, and we never see this data. You can turn this off in Game Center settings on your iPhone, iPad or Mac, or in the Google Play Games app.

Ratings

The app may ask you to rate it. Ratings and reviews are handled entirely by the App Store or Google Play, and the app doesn't see what you choose.

Data Storage and Security

Data Retention and Deletion

Children's Privacy

The app is suitable for all ages and does not collect personal information from anyone, including children.

Changes to This Privacy Policy

We may update this Privacy Policy from time to time. Changes will be posted on this page with a new "Last updated" date.
