Ball Sort Pattern is a puzzle game by Zoran Rajkov. This policy explains what information the app uses.
You can play without an account by choosing "Play as guest". In that case we do not receive your name, email or any other personal information, and you do not appear on the leaderboard.
If you choose "Sign in with Google", Google shares your name, email address and profile picture with the app, and an account is created for you in Google Firebase Authentication. We use it only to identify you on the leaderboard. We do not use your email to contact you and we do not use your profile picture.
When you are signed in with Google, your name, your best level in the timed game and the date of that record are stored in Google Cloud Firestore (servers in Belgium, EU), linked to your account ID. The leaderboard may be shown to other players in a future version of the game.
Your level, record, sound volume and other settings are stored on your device.
The app shows ads provided by Google AdMob. To show and measure ads, Google may collect the device advertising ID, approximate location (based on IP address), app interaction and diagnostic data. In the European Economic Area and the UK you will be asked for consent before personalized ads are shown. You can reset or delete your advertising ID in your device settings (Settings > Privacy > Ads).

How Google uses data from apps: https://policies.google.com/technologies/partner-sites
The app uses Firebase Analytics to understand how the game is used (for example, which levels are played) and to find problems. This data is collected by Google and is not used to identify you personally.
We do not sell your data. Data is shared only with the Google services listed above (Firebase Authentication, Cloud Firestore, Firebase Analytics and AdMob).
The game is not directed at children under 13.
In the app: on the start screen, while signed in, tap "Delete account" and confirm. Your account and your leaderboard entry (name, best level, date) are deleted immediately.
By email: you can also request deletion of your Ball Sort Pattern account and its data by writing to zoranrajkov@gmail.com with the subject "Ball Sort Pattern - delete my account" from the Google email address you used to sign in. We delete the account and the leaderboard entry within 30 days.
Signing out does not delete your account. Game progress stored on your device is removed when you uninstall the app. We do not keep any of your account data after deletion.
