Necessary Always on
Keeps you signed in, remembers that you have seen this notice, and protects the forms against cross-site requests.
Cookie policy
This site sets the smallest number of cookies that still lets it work. Nothing is shared with anybody else: there is no analytics, no advertising and no third party on these pages.
Preferences In use
Remembers the colour and the light or dark mode you picked, so the site looks the same next time.
Statistics Not used
Would count visits, anonymously, to see which pages are read. Not used — and it stays off unless it is really needed.
Marketing Not used
Would be used to follow people between sites and show advertising. Not used, and there are no third parties here.
Your choice
The notice is waiting for you at the bottom of the page. Acknowledging it only stores that you have seen it.
