Privacy and saved games

Where your game is saved

Game progress and readability settings are saved in this browser for this site's address. Readability settings include high contrast, larger tiles, and optional playable-tile outlines. Older saved games load with playable-tile outlines off. A save contains the schema and generator versions, layout ID, deal seed, accepted move history, readability settings, and a revision number. The game rebuilds the remaining tiles and current status from that history. The save stays in this browser and is not sent to a game server.

Saves do not sync to another browser or device. Clearing this site's browser data can remove a save. Private browsing may not keep saves, and browser storage or safe cross-tab coordination may be unavailable. An existing save may still be restored, but changes in memory-only mode will not be saved after the page is closed or reloaded. If a save cannot be read safely, the game explains the recovery choice and does not silently replace it.

Optional usage measurement

You can allow us to measure how this game is used. Choose “Allow measurement” or “No thanks” in the game, and change your choice at any time under View. The game works without measurement. If browser storage is unavailable, your choice applies only in the current tab.

If you allow it, this site sends game events such as a first match, hint, undo, no-moves state, completion, restart, and save outcome to our Cloudflare-hosted measurement service. Events include random page and board identifiers, event time and board size, and a random browser identifier when browser storage is available. They do not include your tile choices, game seed, save contents, name, email, or feedback text. No account is needed, but the identifiers can link events in the same browser; they are not a guarantee of anonymity. A browser or network provider may process network information when handling a request.

Choosing No thanks stops future measurement in this browser and removes its measurement identifier from local storage. Data already received remains until removed by the operator; the service aims to remove events older than 30 days on subsequent activity, and the operator also checks and removes expired records. Provider backups may persist after deletion. The game save is separate and is not removed when you change this choice.

Hosting and request logs

The published site is hosted by Cloudflare Pages. The hosting provider may process ordinary delivery and security request data. Depending on provider operations, that data can include an IP address, requested page, request time, and browser or network details. This hosting data is separate from your game save. The site owner does not set the provider's log retention practices. Refer to the current Cloudflare Privacy Policy for information from the hosting service.

Feedback

The feedback report contains your description, layout ID, deal seed, generator version, and browser viewport. It does not include saved game data or a user ID. You can copy or download the report and send it yourself; browsers that support sharing may also offer a share menu. The game never submits it automatically. Any service you choose to share it with handles it under its own privacy practices.
