SkyStack has no accounts, no sign-in and no analytics. We do not collect your name, email or any personal details. The app shows optional advertising, and to do that Google's advertising service receives a device advertising identifier. Nothing else leaves your device.
The app saves which skins you have unlocked and whether you have bought the starting shield. This is stored locally on your device only. It contains no personal information, is never transmitted to us or anyone else, and is removed when you uninstall the app.
Scores and level progress exist only for the duration of a session and are discarded when the app closes.
The app files themselves (the game, its fonts and icons) are cached on your device so it can run without an internet connection. This cache contains no information about you and is removed when you uninstall the app.
The app offers optional rewarded video adverts. You are never shown an advert unless you choose to watch one — there are no banners and no adverts that interrupt play. Advert delivery is handled by Google AdMob, which may use a device advertising identifier to select and measure adverts. Google's handling of that data is covered by their policy at policies.google.com/technologies/partner-sites.
You can reset or delete your advertising ID at any time in Android Settings under Privacy › Ads. If you are in the EU, UK or a US state with applicable privacy law, the app shows a consent prompt before any personalised advert is served.
Apart from loading adverts you have chosen to watch, the app makes no network requests. All fonts, audio and graphics are generated or bundled locally, and the game is fully playable offline.
The app offers optional one-time purchases. Payment is handled entirely by Google Play; the app never sees, receives or stores payment details. Purchases can be restored on a new device by signing in with the same Google account.
The app has no communication features and no gambling mechanics. Adverts are optional and opt-in. If the app is used by a child, adverts are served on a non-personalised basis in line with Google Play's Families policy.
If a future version adds purchases or analytics, this policy will be updated before that version is published, and the change will be reflected in the app's Data Safety declaration on Google Play.
