Stack the Sky ("the app", "we") is a tower-stacking game for Android. This policy explains what information the app handles.
## Information we collect
We do not collect, store or transmit personal information to our own servers. The app has no accounts, no sign-in, and no in-app purchases.
Data kept on your device only: your best height and the list of landmarks you have collected. This is stored locally in the app's private storage and is removed when you uninstall the app.
## Advertising (Google AdMob)
The app shows ads provided by Google AdMob (Google Mobile Ads SDK). To serve and measure ads, Google and its partners may collect and use:
- Advertising ID (Android advertising identifier)
- IP address and approximate location derived from it
- Device and app information (device model, OS version, app version, language)
- Ad interaction and diagnostic data (ad impressions, clicks, crash and performance data)
This data is handled by Google under its own privacy policy: https://policies.google.com/privacy
How Google uses data from apps that use its services: https://policies.google.com/technologies/partner-sites
## Consent and your choices
Where required by law (for example in the European Economic Area, the United Kingdom and some US states), the app asks for your consent before showing personalised ads, using Google's User Messaging Platform.
You can limit ad personalisation on your device: Android Settings > Google > Ads > "Delete advertising ID" or "Opt out of Ads Personalization".
You can also uninstall the app at any time to stop all data processing by the app.
## Children
The app is not directed to children under 13 (or the applicable age in your country), and we do not knowingly collect personal information from children.
## Third-party services
Google Mobile Ads SDK (AdMob) — https://policies.google.com/privacy
## Data retention and security
We keep no personal data on our own servers. Locally stored game data stays on your device until you clear the app's data or uninstall it.
## Changes to this policy
We may update this policy from time to time. The "Last updated" date above shows when it last changed. Continued use of the app after a change means you accept the updated policy.
