We collect and store no personal information ourselves. There is no sign-up, no login, and no account of any kind. The app does include an advertising SDK (Unity Ads), which processes the data below to serve ads (see section 3).

Advertising identifier (GAID), IP address and device information — processed by Unity Ads for ad delivery and fraud prevention.
There is no analytics, crash-reporting or attribution SDK in the app.

All of it stays on your device. There is no account, no cloud sync and no server of ours.

3. Third-party services

Google Play Billing — in-app purchases are processed by Google, and the app only checks whether you own an item. We never see your payment details. Google's handling is covered by the Google Privacy Policy.

Unity Ads (Unity Technologies) — to serve interstitial and rewarded ads, it collects and uses the advertising identifier (GAID), IP address, device information (model, OS version, language, etc.) and ad-interaction data, which may be passed to advertising partners during ad bidding. Unity's handling is covered by the Unity Privacy Policy, and you can opt out of personalized ads via the information icon shown on ads.

Data listed in section 3 may be processed on Unity Technologies servers abroad (e.g. the United States) as part of ad delivery. We transfer no personal data ourselves.

5. Advertising and tracking

This app shows interstitial and rewarded ads. There are no banner ads.
The "Remove Ads" in-app purchase removes all ads.
You can reset or delete your advertising ID at any time in your device settings.
