Privacy Policy

Last updated: May 19, 2026

Sudoku Unlimited+ is developed and published by Lauterstar LLC. This policy explains what information the app collects (very little), how it is used, and your rights.

What we collect

Sudoku Unlimited+ stores all game data — your puzzles, settings, statistics, and solve history — locally on your device using your device's built-in storage. This data never leaves your device and is not transmitted to our servers or any third party.

We do not collect:

Notifications

If you enable daily reminders in Settings, the app schedules local push notifications. These are generated entirely on your device — no data is sent to our servers to deliver them.

Third-party services

The current version of Sudoku Unlimited+ does not use third-party analytics, advertising SDKs, or tracking frameworks. The current version contains no ads.

Apple App Store

When you download the app through the App Store, Apple collects certain data per their own Privacy Policy. We have no control over and no access to that data.

Children

Sudoku Unlimited+ does not knowingly collect any personal information from children under 13. Because the app collects no personal data at all, it is safe for users of all ages.

Changes to this policy

If we make material changes to this policy, we will update the "Last updated" date above. Continued use of the app after changes constitutes acceptance of the updated policy.
