Cookie Policy

Strictly necessary

One cookie holds a randomly generated session identifier. It lets your answers survive a page refresh and stops the same visit being counted twice. The site cannot work correctly without it, so it is set without asking.

Advertising and measurement

Google and its advertising partners set cookies to serve ads, to limit how often you see the same ad, and to measure performance. Where the law requires it, these are only set after you consent.

Advertising platforms may also set cookies to attribute your visit to the campaign that brought you here.

Managing cookies

You can change or withdraw your consent at any time through the privacy settings link in the consent banner.

Every major browser also lets you block or delete cookies in its settings. Blocking them will not stop you taking the tests, but some things — such as resuming a test after a refresh — may stop working.
