Cookies

This website does not use advertising cookies or tracking cookies. It only uses what is strictly necessary for the website to work and stay secure.

When you choose a language or a country in the menus at the top of the page, we save that choice in a small cookie (called ch_lang or ch_country) for one year, so the website opens in your language and country next time. They hold nothing else and are not used for tracking. We also use the country your request comes from, which your connection gives us, to show you your country’s page first. We do not store it.

We count visits to the website with Vercel Web Analytics. It uses no cookies, stores nothing on your device and keeps no personal data: only anonymous totals, such as how many people visited a page.

If we add analytics or other optional cookies in future, we will ask for your permission first and update this page.
