Cookies
A short, honest summary of every cookie this site sets.
Last updated: 22 May 2026.
What cookies are
Cookies are small text files that a website stores on your device. We use a very small number of them — none are set before you decide.
What we set if you accept
Google Analytics 4 (`_ga`, `_ga_*`) — measures aggregate site usage so we can improve content. The approved Google Tag Manager container loads optional analytics and marketing tags only after you click 'Accept optional cookies' in the consent banner.
What we set even if you decline
A single first-party preference key (`co_consent_v1`) stored in your browser's localStorage where available, with a same-name first-party cookie fallback if localStorage is unavailable, so we don't ask again on the next page view. It contains only your accept/reject choice.
Changing your mind
Use Cookie settings in the footer at any time to see or change your choice. Choose Reject optional cookies to withdraw permission for optional analytics and marketing. If tracking has already loaded, the page reloads to stop those scripts; unsaved entries may be lost. We remove known tracking cookies accessible to this site, but cannot remove all third-party cookies or erase data already sent. No manual clearing of browser data is needed.
