Privacy and advertising
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
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 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.
