Cookie Policy
Last updated: 19 September 2026
This site asks before it sets anything that is not strictly necessary, and nothing in the statistics or marketing categories runs until you say so. This page lists what each cookie is for.
What a cookie is
A small file a site stores in your browser so that it can recognise the same browser later. The same rules are applied here to comparable technologies, including anything kept in your browser's local storage.
Necessary
These make the site work: they keep your session, remember your language, protect the forms from automated abuse, and record the cookie choice itself. They carry no advertising and cannot be switched off, because without them the site does not function. They are set on the basis of legitimate interest and do not require consent.
Statistics
First-party measurement, built into this site rather than bought in. It counts page views, time on page, scroll depth and click positions, and the data stays on this server. It is used to see which pages are read and which are ignored. Off unless you allow it.
Marketing
Meta Pixel, TikTok Pixel and Google Tag Manager, used to measure advertising campaigns and to attribute enquiries to the campaign that produced them. These involve third parties who process data outside the European Union. Off unless you allow it — and until you do, the scripts are not loaded at all, rather than loaded and told to behave.
Changing your mind
Use the link in the footer of any page. Withdrawing is one click, exactly like giving.
You can also delete cookies through your browser's settings, and set it to refuse them. If you do, this site will ask again on your next visit, and parts of it may not work.
