Audience measurement

To understand how the site is visited, the group measures its audience with Umami, open-source software hosted on its behalf on a server located in Frankfurt (Germany). The data is neither sold nor used for advertising. The measurement sets no cookies.

What is measured: the pages viewed and their sequence during a visit, the referring site or campaign, the approximate country and city, the device type, browser, operating system, language and screen size, reading time and scrolling, page speed, and clicks on the e-mail address, outbound links and the language switch.

Your IP address is used for a moment to identify the network the visit comes from (the operator or organisation holding the network, and the associated domain name). It is then discarded: it is neither stored nor logged. A non-reversible fingerprint, renewed every month, groups the pages of a single visit. This processing is based on the group’s legitimate interest in knowing how its site is visited and which organisations take an interest in it. Measurement data is kept for twenty-five months, then deleted.
