Cookie Policy
Last updated 25 September 2026
In plain English
- We only use cookies that the site needs to work: keeping you signed in, protecting forms and remembering that you have seen this notice.
- We do not use analytics, advertising or tracking cookies, so we do not ask for cookie consent.
- If that ever changes, we will update this page and ask for your consent first, with an equally easy way to say no.
