Cookies and measurement

We measure site usage in two layers.

1. Cookieless measurement (always on)

Nothing is stored in your browser. The server computes an anonymous identifier from a random value that is replaced every day and discarded, together with the IP address and browser. The IP is not stored. You cannot be recognized from one day to the next.

2. Measurement cookies (only with your permission)

Global Privacy Control and Do Not Track are honored as a refusal. You can change your choice under "Cookie preferences" in the footer.
