3. Cookies and local storage

The site shows no advertising and uses no advertising trackers or tracking cookies. It only stores:

  • your chosen language (functional cookie set by the Polylang plugin);
  • your display and accessibility settings (theme, text size…), stored in your browser and never sent to the server.

Audience measurement: to know which pages are read, the site uses Matomo, installed on its own server at Infomaniak. It works without cookies, only keeps anonymised IP addresses (the last two bytes are masked), respects your browser’s “Do Not Track” setting, and the statistics are shared with no one. This setup meets the CNIL’s conditions for consent-exempt audience measurement.

These are strictly necessary for the features you request or exempt from consent. Fonts and images are hosted on the site’s own server: no call is made to Google Fonts or an image bank during your visit.
