Guess the Language uses a small number of browser storage keys to keep your game working and to understand, in aggregate, how the game is played. Signing in adds one storage key that keeps your session. Our own storage is never used to build advertising profiles; ads on the site are served by Google AdSense, which sets its own cookies (see below).
gtl.progress
Local storage
Your level, highest level reached, score history, identified languages and guest id, so progress survives a reload.
gtl.session
Local storage
Lives and score for the run currently in progress.
gtl.sound.enabled
Local storage
Remembers whether you turned game sound on or off.
gtl.analytics.session
Local storage
A random id used to group gameplay events from one visit. It is not linked to your identity and contains no personal data.
_ga, _ga_*
Cookie (Google Analytics)
Set by Google Analytics 4 to measure visits and which pages and game events are used. Retained for up to two years.
Analytics
We use Google Analytics 4 to count visits and gameplay events such as a run starting, an answer being submitted or a clip failing to load. These events carry no names, emails or other personal identifiers — only the game context needed to balance difficulty and fix audio problems.
Advertising
The site shows ads served by Google AdSense. Google may set cookies or use device identifiers to measure and personalise the ads you see. You can review and change your ad settings in Google's Ad Center, and block or clear these cookies in your browser settings.
Removing this data
Clearing site data (or cookies and local storage) for this site in your browser settings removes everything listed above, including your saved progress. You can also block cookies for this site entirely; the game will still play, but progress will not persist.
