Cookie Policy
The cookies this website uses
A short list, because we only use the cookies the site needs to work. No tracking or advertising cookies.
Last updated: 25 September 2026
What cookies are
Cookies are small text files a website stores in your browser. Some are needed for the site to work; others track what you do. We only use the first kind.
Cookies we set
| Cookie | What it does | How long it lasts |
|---|---|---|
| XSRF-TOKEN | Security. Proves that a form submission really came from this site, which blocks a type of attack called cross-site request forgery. | 2 hours |
| Session cookie (its name ends in "-session") | Keeps your visit working from one page to the next and, if you sign in, keeps you signed in. Your browser cannot read it with scripts. | 2 hours after your last visit |
| remember_web_… (only if you tick "Remember me" when signing in) | Keeps you signed in on this device between visits. | Until you sign out, or up to about 400 days |
| bm_cookie_consent | Remembers whether you accepted or rejected optional cookies, so we do not ask again on every page. | 180 days |
All four are strictly necessary. They do not track you across other websites and are not used for advertising.
Optional cookies
We do not currently use any optional cookies, such as analytics or advertising cookies. If we ever add them, they will only be set after you choose "Accept" in the cookie banner, and this page will list them first.
Other services
The fonts on this site are served from our own server. The map of our centres loads its images from OpenStreetMap, which receives your IP address when your browser fetches them (see the Privacy Policy) but does not set cookies through this site.
Changing your choice
Use "Cookie settings" at the bottom of any page to see the banner again and change your answer. You can also delete cookies in your browser settings at any time. If you block the strictly necessary cookies, the forms and signing in will stop working.
