Privacy and advertising
iOS and Android apps
Automatic and manual saves, recovery keys and language settings are stored in the app’s private device storage. Depending on OS and device settings, they may be included in device backups or transfers. Removing the app may remove local data. To continue on another device, first save to the cloud and keep your recovery key, or export a JSON save file. Cloud saving is manual, not automatic synchronization. The app uses Google AdMob and the UMP consent SDK for a bottom banner and may show a full-screen ad when returning to the game after a successful cloud save or when starting another campaign after the first one. Cloud saving completes before any ad, and saving and play continue when no ad is available. Google may process IP addresses, device information and ad interactions for delivery, measurement and fraud prevention. We request non-personalized ads and do not request ATT permission. Where required, consent is gathered before ad requests and Ad privacy choices lets you revisit your decision. Saves and recovery keys are not passed to ads. Playing and saving remain available without ads, including when offline or when consent or inventory prevents serving. Development builds use Google test ads. No analytics SDK is bundled. Sharing, clipboard access and file selection are used in response to your actions. External sites opened from the app have their own privacy notices.
Saved games
Local automatic and manual saves and your cloud recovery key are stored in your browser. Game data is sent to Cloudflare D1 only when you choose cloud saving. Anyone with the recovery key can read or modify that save. Use the cloud-save panel to delete it. Clearing browser data does not delete a cloud save.
Analytics and operation
On the Web version, Cloudflare Web Analytics measures visits and loading performance. Our own event tracking aggregates page, language, game mode, ad opportunities and outcomes, post-ad interactions and campaign slugs. It uses no cookies or visitor IDs and sends no save contents or recovery keys. DNT/GPC disables our own event tracking. Cloudflare processes network information such as IP addresses for delivery and abuse prevention; IP addresses also support save API rate limits.
Current advertising status
Ads are currently disabled in the normal Web game. We plan to use Google H5 Games Ads at transitions after saving or before a new game replaces the current one. First starts have no ads, and ad availability does not affect saving. Required regional consent management and this notice will be updated before enabling ads. The separate operator test page connects to the Google SDK only when its preparation button is pressed.
