The short version
Chainle has no accounts and no database of players. There is no server-side profile of you. Your game progress is stored in your own browser, and the only data that leaves your device is the word you guess, which is sent to our server to be scored.
What is stored in your browser
The game writes one item to localStorage under the key chainle_state_v1. It contains your current streak, your best streak, the date of your last completed puzzle, and the number of guesses and hints you used for recent days. It contains no name, no email, and no identifier that could be traced back to you. Clearing your browser storage deletes it permanently, and the game continues to work without it.
What our server sees
When you submit a guess, the request includes the puzzle date, the round number and the word you typed. The server uses these to compute a similarity score and returns a number. Guesses are not written to a database and are not associated with an identity. Standard web-server logs and our hosting provider may record request metadata such as IP address, user agent and timestamp for security and abuse prevention.
Cookies and analytics
Chainle does not set its own cookies. If analytics are enabled on this deployment, they are loaded through an environment-configured measurement ID and may set cookies or collect aggregate usage data such as page views and country. Analytics are optional: when no measurement ID is configured, no analytics script is loaded at all.
Advertising
If advertising is enabled, ads are served by Google AdSense using the publisher ID configured for this domain. Google may use cookies to serve ads based on your prior visits to this and other websites. You can opt out of personalised advertising in your Google account settings, or manage cookies in your browser. When no publisher ID is configured, no advertising script is loaded.
Children
Chainle is a general-audience word game. It does not knowingly collect personal information from anyone, including children, because it does not collect personal information at all.
Your choices
You can clear your game data at any time through your browser settings. Blocking cookies does not prevent you from playing. If you are in a jurisdiction with data-protection rights, the most relevant fact is that we hold no personal data about you to access, correct or delete.
