What we store in your browser
The site sets no first-party cookies for its own functionality. It uses local storage for the following:
- cf-session: a random identifier used to count free decisions and de-duplicate analytics events.
- Draft state: the state and questions you have typed in the playground, so a refresh does not lose them.
Third-party cookies
The analytics provider sets cookies to distinguish visits and count page views. Google Analytics 4 sets cookies to attribute sessions. Google AdSense, where ads are shown, may set cookies including the DoubleClick cookie to select and measure advertising.
Managing them
You can delete or block cookies and local storage in your browser settings. Blocking analytics cookies does not affect the playground. Blocking advertising cookies may result in non-personalised ads rather than no ads.
