Cookie policy
Last updated: 3 October 2026
Cookies and similar technologies (like your browser's local storage) are small pieces of information a website saves on your device. We use as few as possible, and we never use advertising cookies.
What needs your consent
Necessary items and preferences you ask for (like the language you choose) don't need consent: the site can't work as you expect without them. Measurement and analytics only switch on if you accept them in the cookie banner. If you reject them, the site works exactly the same.

Changing your choice
You can change or withdraw your consent at any time. If you withdraw it, we delete the analytics cookies from your browser.
You can also block or delete cookies in your browser settings. Google offers a browser add-on to opt out of Google Analytics.
