The game "Tetromino-3D: Survival Extreme", further on in the context called "the app", developed by Psychonautek Games-Studio doesn't gather or save any direct user data.
Further on "the app" doesn't gather any direct geolocation nor does "the app" need internet-connectivity for main functionality!
"The app" contains banner ads as well as interstitial ads integrated with Google Ads mobile SDK for Unity which will only collect analytic data from the users when watching an ad.
