The short version
WORLDSTACK requires no account and is fully playable offline. We ourselves collect no personal data. If you choose to watch an optional rewarded advertisement, our advertising partner (Google AdMob) may collect limited device data to show and measure that ad, as described below. That data is not linked to your identity and is not used to track you across other apps.

Data we collect
We — the developer — do not collect, store, or transmit any personal information. The app has no accounts, no location access, no contacts access, and no developer analytics.
Advertising (Google AdMob)
The game may offer optional rewarded advertisements (for example, doubling a run's Star Dust). Ads are never shown during gameplay and never play unless you tap the ad button. To serve and measure these ads, the Google Mobile Ads SDK (Google LLC) may collect: device identifiers, IP address, ad interaction data (which ads were viewed), and diagnostic data. This data is not linked to your identity and is not used for cross-app tracking — the app does not use Apple's advertising identifier (IDFA) and never shows the App Tracking Transparency prompt. Where the law requires it (for example in the EEA/UK), a consent form is shown before any ad request, and ads remain non-personalised without your consent. You can revisit your choice at any time via Settings → Ad privacy choices in the game. See Google's Privacy Policy and how Google uses data from partner apps.
Data stored on your device
Your game progress, settings, and run history are saved in the app's own local storage on your device. They are never uploaded anywhere. Deleting the app deletes this data.
Purchases
This version of the game contains no in-app purchases. If a future update adds optional purchases, this policy and the App Store listing will be updated before that version is released.
Children
The game is suitable for all ages. Advertising, when present, is configured for general audiences and is non-personalised without consent; we never knowingly collect personal information from children.
Your rights
Since no data about you is collected or held by us, there is nothing for us to access, correct, export, or delete on your behalf — everything stays on your device, under your control.
Changes to this policy
If this policy changes, the new version will be posted at this address and the effective date above will be updated.
