Brinechart privacy
Saved on this browser
Brinechart saves your current chart, marks and hint history in this browser’s local storage. There is no account or cross-device sync. Progress is not sent by the game to a server.
The game uses the key brinechart-battleships-v1. Closing private browsing, clearing site data or changing browsers may remove your progress.
Protected records
If a saved record is damaged or uses an unsupported format, saving pauses. You can keep playing in the tab, read the record again, or explicitly replace it. When another tab changes the saved charts, this tab stops saving until you read the updated record.
Requests and hosting
The game loads its pages and files from its host. Hosting services may process normal request information, such as an IP address and requested page, to deliver them. These pages include no analytics script, advertising script or third-party font request. Links to rule publishers open their websites, where their own policies apply.
Delete saved charts
Delete Brinechart progress on this browser. Other games’ records are kept. Close any other Brinechart tabs first, so they do not save again.
