Data stored on the device
The game stores gameplay progress, settings, language and difficulty, lives and regeneration timing, equipment, tools, tunnel and boss progress, temporary ad rewards, the selected age group used to configure ads, and a local cache indicating whether the ad-removal purchase was previously verified. Gameplay data may be backed up by Android according to device or account settings; the purchase-entitlement cache is excluded from app backup.
Advertising and consent
The game uses Google Mobile Ads and Google User Messaging Platform (UMP). Where required, UMP presents privacy and consent choices before an ad request is made. Before ads are initialized, the game also asks for the player’s age group so that the appropriate advertising mode can be configured. Google and its advertising partners may process technical device data, advertising identifiers, consent status, approximate network information, interactions and diagnostic data to the extent permitted by the age mode, consent choices, applicable law and Google policies. The developer does not use a separate analytics SDK in this build.
Purchases
The optional Remove Forced Ads purchase is handled by Google Play Billing. To verify ownership, the game sends the Google Play purchase token, package name and product ID over HTTPS to a developer-operated verification service. That service verifies the purchase through the Google Play Developer API and acknowledges it where required. The verification service is designed without a persistent database of purchase tokens. The developer does not receive full payment-card details.
Permissions
The game does not request contacts, photos/media library, camera, microphone or precise location for gameplay. Internet access is required for advertising, consent and online purchase verification or restoration.
External providers
Google Play processes purchases. Google Mobile Ads and UMP provide advertising and related consent handling. The purchase-verification service is designed for Cloudflare Workers and communicates with the Google Play Developer API. These providers may process technical network and service data under their own terms and privacy policies.
Retention and deletion
Local gameplay data remains on the device until it is cleared or the app is uninstalled, subject to Android backup behavior. The developer-operated verification service is designed without a player account and without a persistent purchase-token database. Provider operational logs may exist according to their configuration and retention policies.
Children
The target-audience setting in Play Console, advertising configuration and consent configuration must match the audience of the published build. When the child age group is selected, the game configures an age-restricted ad mode and a maximum ad-content rating of G before requesting ads. Rewarded ads remain optional.
Security
The app disallows cleartext network traffic and production purchase verification requires HTTPS. No method of electronic transmission or storage can be considered absolutely secure.
