Privacy and Local Data

Game progress stays in your browser

We use browser local storage for your current game, original deal, recent undo history, settings, elapsed play time, and personal game statistics. These records are used by the game on your device. We do not send the contents of saved games to an account service or a global leaderboard.

You can remove these records through your browser’s site-data settings for games.globalcorehub.com. Clearing site data deletes saved games and statistics. Restricted or private browsing can make storage temporary or unavailable; a storage warning appears when we detect a problem.

Offline caching

A service worker stores site files and visited game pages in the browser’s Cache Storage so they can load again without a connection. This is separate from game-progress storage. The browser may remove caches under storage pressure.

Removing site data or unregistering the service worker disables that stored offline copy. Normal updates replace cached files while preserving compatible game saves. No permission to read other websites’ files is requested.

Hosting and optional measurement

Cloudflare delivers this site and processes network request information needed to provide and protect the service, such as IP addresses and browser request headers. Its handling of infrastructure data is governed by its own policies.

Cloudflare Web Analytics may be enabled through the hosting account or a configured site token to measure visits and performance. The optional integration does not upload game saves or implement player profiles. Google Search Console, when connected by the operator, reports search and indexing information; site verification itself does not add a player-tracking script.

The game does not require analytics requests to succeed. Blocking optional measurement does not prevent play. At launch, no advertising network is loaded by this application.

External links and public feedback

A public feedback channel has not been opened at launch. If an external support link is added later, that service will have its own privacy practices. Do not put private data in public reports. We do not collect your name or email through a game registration form.

We do not sell game-progress records or offer a data marketplace. If future features change what the application collects, this page should be updated before those features are enabled.
