Cookie policy

Last updated 5 September 2026.

A cookie is a small file a website asks your browser to keep. This site uses as few as it can, and nothing on it is loaded from a third-party server, so no other company receives anything about your visit.

What we set

sb_consentRemembers whether you accepted or declined optional cookies, so the notice is not shown again. Strictly necessary, set only once you have chosen. Expires after 12 months.

Optional cookies

If you choose Accept all, we may set analytics cookies to count visits and see which pages are read. These are first-party and are never used for advertising or shared with anyone. If you choose Essential only, none are set.

Changing your mind

Select Cookie settings at the foot of any page to see the notice again and make a different choice. Clearing your browser's cookies for this site has the same effect.

Blocking cookies

Every current browser can block or delete cookies from its settings. This site works normally with cookies blocked — you will simply see the notice on each visit, because the choice cannot be remembered.
