Cookie policy

No marketing cookies, no cross-site tracking, no fingerprinting. Here's exactly what we set and why.

Last updated: May 8, 2026

1. What is a cookie?

A cookie is a small text file stored by your browser. It allows a website to remember information between visits — for example, your login status.

2. The cookies we set

2.1 Strictly necessary cookies (no consent required)

These cookies are essential to the operation of the site. Without them, you can't log in or use the main features. They are allowed without consent under Article 82 of the French Data Protection Act (and equivalent laws).

admin_sessionAdmin authentication (internal only)Session

cookie_consentStores your consent choices12 months

2.2 Analytics cookies (with your consent)

If you accept analytics cookies, we use Vercel Analytics and Vercel Speed Insights to measure site performance and aggregate usage. Vercel Analytics sets no third-party cookies and uses a privacy-by-design approach (no raw IP, no cross-site fingerprinting).

You can refuse or withdraw your consent at any time via the banner at the bottom of the page.

3. What we DO NOT do

  • ❌ No advertising cookies (Google Ads, Meta Pixel, TikTok, etc.)
  • ❌ No cross-site tracking
  • ❌ No fingerprinting (canvas, WebGL, fonts)
  • ❌ No selling data to third parties
  • ❌ No commercial profiling
