Privacy Policy for Under-Grid

Last updated: October 19, 2026

Under-Grid ("the game") is a single-player game for Android made by serginator ("I", "me").

Short version

The game does not collect, send, share or sell any personal data. It has no account, no ads and no analytics. It works without an internet connection.

What the game stores on your device

The game saves this data on your device only, so that it can work:

• Your current run (map, deck, HP, credits).
• Your settings (volume, music style, language, vibration, screen effects, and whether you saw the tutorial).
• Your high scores, including the three-letter initials that you type.
• Your Bestiary progress (which enemies you defeated).

This data never leaves your device. I cannot see it. You can delete all of it at any time: clear the app data in the Android settings, or uninstall the game.

Permissions

The game asks for the vibration permission, so that it can vibrate when you play chips. It does not ask for the internet, your location, your contacts, your camera, your microphone, your files or your identity.

Third parties

The game contains no advertising, no analytics, no crash reporting and no third-party tracking tools. The game is distributed by Google Play. Google may collect data about your use of Google Play under its own privacy policy: https://policies.google.com/privacy

Children

The game is not made for children under 13. I do not knowingly collect data from anyone, because the game collects no data.

Changes

If this policy changes, I will publish the new version at this address and change the date above.
