Cookies

Open Bracket only sets cookies that are strictly necessary to run the site — nothing for analytics, advertising, or tracking you across other sites. Because of that, there's no cookie-consent banner: everything below is "strictly necessary" under UK cookie law and doesn't legally require one.

What we use

• sessionid — keeps you signed in between requests. Set once you sign in; removed when you sign out.
• csrftoken — a standard security token that stops other sites from submitting forms on your behalf.
• ob_guest — a signed cookie linking a guest attempt back to you if you play without an account, for up to seven days.
• A short-lived cookie from Cloudflare Turnstile while it checks you're not a bot on sign-up, sign-in, and password recovery.
