Cookies

No adverts, and nothing that follows you to another site. What we set is what signing in and the forum need. We count page views with Umami, which sets no cookie and identifies nobody. The one exception is Cloudflare Turnstile, which checks our forms are being used by a person, and that one is yours to decline — nothing is loaded from Cloudflare while you read until you say so. The sign-in, sign-up and password-reset pages always use it. No adverts, and nothing that follows you to another site. We count page views without a cookie and identify nobody.

Strictly necessary — signing in, the forum, and remembering this choice. Always on, because without them the site cannot do what you asked of it.

Spam protection — Cloudflare Turnstile on the contact form and the forum editor. Declining means it is never requested while you read; you will be asked again only if you go to use one of those forms. The sign-in, sign-up and password-reset pages always use it.
