How do I change or switch off ads?

Ads start at Minimal: a small banner on Home and under the game. To change it, tap the ‹ under the gear on Home and pick the heart (Ads), or go to Settings → Support. Off is always there, free, no catch.

How do I turn off personalized ads?

Settings → Support → Personalized ads. Players under 18 only ever get non-personalized ads. Where the law asks for it, Settings also has Privacy choices to change what you agreed to.

Will my stats move to a new phone?

Yes, if Android Backup is on for your Google account (Settings → Google → Backup). Android restores the app's data when you install it on the new phone. Your games never pass through us.

How do I delete everything?

Android Settings → Apps → Sudoku → Storage → Clear data. Or uninstall. We don't keep a copy, because we never had one.

Deleting data collected by ads

We don't receive any data. What Google's ad software collects is managed by Google: myadcenter.google.com. You can also reset your advertising ID in your phone's settings.

Found a bug?

Write to support@cleanbuilds.dev with your phone model and what happened. A screenshot helps. The app version is at the bottom of Settings.
