Retention period
Data is kept for as long as needed to handle your request, then for no more than three years after the last contact, unless a contractual relationship is ongoing.
Cookies and audience measurement
This website uses Google Analytics 4 (Google Ireland Limited) to measure its audience: page views, where visits come from, device type. These cookies (_ga and _ga_*) are set only with your consent, collected through a banner when you arrive; refusing is as easy as accepting and does not prevent you from using the website. They last no more than 13 months and your choice is requested again after 6 months. No advertising cookies are used and the data is not used for any targeting.
Measurement data is kept for 2 months in Google Analytics. Google may process it in the United States under the EU–US Data Privacy Framework. You can withdraw your consent at any time by clicking “Manage cookies” at the bottom of any page: the Google Analytics cookies are then deleted.
Your theme (light or dark), language (French or English) and cookie preferences are stored locally in your browser; they are never transmitted.
