Grumpy Gramps Games
Last updated: September 20, 2026

The short version: our apps collect nothing.

Grumpy Gramps Sudoku does not collect, store, transmit, or share any personal information. It has no network access and requests no permissions.

What we collect

Nothing. The app has no internet permission. It cannot send data anywhere, because there is no code in it that could.

What is stored on your device

Your puzzles, progress, statistics, trophies, and settings are saved on your phone, in the app's own private storage. They never leave your device. Uninstalling the app deletes them.

Third parties

None. No analytics, no advertising, no crash reporting, and no software development kits from other companies.

Children

The app collects no data from anyone, including children.

Changes

If this policy ever changes, the updated version will be posted here with a new date.
