Cookie management
The CRGE website only measures its audience with your consent.
Audience measurement
With your consent, the website measures its audience with Matomo: pages viewed, visit length, referring site, type of device. Matomo then sets the _pk_id (13 months) and _pk_ses (30 minutes) cookies.
These statistics are only used to improve the website. They are neither sold, nor combined with other data, nor used for advertising.
The website uses no advertising and no social media buttons. You can change your choice at any time below; refusing deletes the audience measurement cookies.
Language preference
When you choose French or English, this choice is stored for one year in the preferred_locale cookie, so the website opens in the same language on your next visits. Only the website reads it, and it is not sent to anyone else.
Strictly necessary for the service you ask for, this storage requires no consent (article 82 of the French Data Protection Act). You can delete it at any time in your browser settings.
Contact form
Sending the form passes your request to the website's server, which stores it, without placing any cookie on your device. The form may show the Cloudflare Turnstile anti-bot check: strictly necessary for the security of the form, it does not require consent. How your information is processed is described on the Personal data page.
