Cookie policy

01What cookies are

A cookie is a small file your browser stores when you visit a website. Besides cookies, the site uses your browser’s local storage to keep data right on your device.

02Essential cookies (always on)

• Sign-in session: keeps you signed in securely; the cookie is HttpOnly so page scripts cannot read it.
• Security: protects against forged requests and limits sign-in attempts.
• Your cookie consent choice.

03Browser storage

• Question sets and lessons while you are not signed in.
• Game settings, rooms you are hosting, practice in progress.
• This data is not sent to our servers; clearing site data in your browser removes it.

04Analytics and advertising cookies (consent required)

If the site enables analytics (such as Google Analytics) or advertising, they only run after you accept in the cookie dialog. You can change your mind at any time.

05Managing cookies

You can delete or block cookies in your browser settings. Blocking essential cookies stops you signing in, but you can still play the games that need no account.
