Cookies, explained without the jargon
Last updated 1 September 2026. What we set, why we set it, and how to switch it off. Short version: we use as few cookies as the site needs to work.
What cookies actually are
A cookie is a tiny text file a website saves in your browser. It remembers things — that you've dismissed a banner, that your session is secure, which map you looked at. Cookies can't run code, can't read your files, and can't identify you by name unless you've given us that information yourself.
This site uses three categories: strictly necessary, preference, and one third-party map embed. That's the whole menu.
| Category | What it does | Lifespan |
|---|---|---|
| Essential | Keeps the site secure and working — session and security tokens. These can't be switched off. | |
| Preference | Remembers your cookie choice so the banner stops asking. Stored locally in your browser. | |
| Analytics | None. We don't run tracking analytics on this site. |
