1. What is a cookie?
A cookie is a small text file placed on your device (computer, tablet, smartphone) when you visit a website. It allows the site to remember information about your visit and may be used for functional, analytical, or advertising purposes.
2. Cookies and technologies used by the Platform

2.5 Local storage (localStorage)
The Platform uses localStorage to store your cookie consent choice (key proxia_cookie_consent) as well as your authentication token. This data does not leave your browser and is not a cookie in the strict sense.
3. Manage your preferences
On your first visit, a banner lets you accept all cookies, refuse all non-essential cookies (just as easily as accepting them, in line with CNIL requirements), or customize your choices by category.
You can change your preferences at any time using the button below or the "Manage cookies" link available in the footer.
4. Consequences of refusal
Refusing non-essential cookies does not prevent you from using the Platform. Only certain audience measurement, performance, or error monitoring features will be disabled.
5. Retention period
Your consent choice is kept for 13 months (395 days) in accordance with CNIL recommendations, after which you will be asked again.
