Cookie policy

1. Necessary cookies (no consent needed)

Login and security do not work without these, so they do not need separate consent. None of them is for advertising or tracking.

Other services: if you use the "Continue with Google" button or the human check (Cloudflare), those companies' pages or scripts may use their own cookies or storage. They are not ours and follow their own policies. Their scripts may load when the page opens, even if you do not press the button.

• mb_at: recognises you while logged in (access token), about 15 minutes. Code on the page cannot read it.
• mb_rt: renews your login (refresh token), up to 30 days, only sent with login-related requests. Code on the page cannot read it.
• mb_s: says "someone may be logged in" (holds no secret), up to 30 days.
• mb_csrf: stops other sites sending requests in your name, 30 days.
• mb_anon: a random identifier used to record your answer to the cookie notice, 1 year. It is created when you answer the notice.
• mb_consent: remembers your cookie decision, 1 year.

2. Optional cookies (only with your permission)

In future we may use analytics cookies to understand how the site is used. They will never be switched on unless you choose "Accept all cookies". No such cookies are in use now.

3. Changing your mind

Press "Cookie settings" at the bottom of the page to open the notice again. You can also delete or block cookies in your browser settings; if you block the necessary ones, logging in will not work.

4. When the notice is updated

If the version of this policy changes, you will be asked again.
