The necessary cookie

• Name: jcl_choix
• Purpose: remembering your choice in the cookie banner, so that it does not reappear on every page.
• Duration: 365 days.
• Set by: this site.

This cookie is needed to respect your choice; it cannot be switched off from the banner.

Audience measurement, optional

If you click "Accept all" or enable audience measurement in the panel, Google Analytics sets its visit statistics cookies. These are the _ga cookie and the _ga_ cookie followed by our property identifier, each lasting no more than two years (the Google Analytics 4 default). If you decline, no measurement cookie is set and the content of the site stays exactly the same.

Before you choose: cookieless signals

Google Tag Manager is loaded on every page in Google's advanced consent mode. Before you choose and after you decline, no measurement cookie is set, but Google Analytics may send cookieless signals to Google: technical requests with no persistent identifier, which Google uses to model overall traffic to the site. Details are in our privacy policy.

No advertising cookies

The site uses no advertising pixel, no remarketing cookie and no social network tracker. In Google's consent mode, the ad_storage, ad_user_data and ad_personalization signals are denied at all times: nothing in the banner can grant them.

Changing your choice

An icon remains at the bottom left of the screen. It reopens the panel, where you can accept or withdraw audience measurement at any time. You can also delete cookies from your browser settings.

Further information

The processing of measurement data is described in our privacy policy. For the measurement itself, see Google's privacy policy (official source, opens in a new tab).
