Cookie Policy

What cookies are

Cookies are small text files a site stores in your browser. Some are needed for the site to work; others are set by third parties such as advertising and analytics providers.

Cookies this site needs

• Session cookie. Keeps you signed in and links your practice run to your account.
• CSRF token. Protects forms from being submitted by another site on your behalf.

These cannot be switched off without breaking sign-in.

Browser storage, not cookies

Your theme choice, your preferred test length and your last 200 signed-out results are kept in your browser's local storage. They never reach our server. Clearing your browser data removes them.

Third-party cookies

If advertising is enabled, Google and its partners may set cookies to measure and personalise adverts. If analytics is enabled, Google Analytics sets cookies to count visits. Manage these through Google Ad Settings or your browser's cookie controls.

Turning cookies off

Every major browser lets you block or delete cookies. Blocking them entirely will stop you signing in, but practice itself will still work — the site is designed to be fully usable signed out.
