This document is translated for information. In case of divergence, the French version prevails.
We use as few cookies as possible. None is advertising, none follows you from one site to another.
1. Strictly necessary cookies
Session: stores an opaque identifier after you sign in. It contains no data about you — only our server knows what it refers to. Duration: thirty rolling days. Without it, staying signed in is impossible.
Sign-in verification: a temporary cookie, valid ten minutes, protects the return from Google or GitHub against a forged sign-in attempt.
Display preferences: language, units and theme, when you change them.
These cookies need no consent (article 129 of the Belgian law of 13 June 2005), because the service you asked for cannot work without them.
2. Audience measurement
Where enabled, cookieless audience measurement stores nothing on your device and collects nothing that identifies you.
Should a tool that sets cookies ever be used, it would load only after your explicit consent, revocable at any time.
3. Payment
Payment happens on a page hosted by our provider, which sets its own cookies necessary to the security of the transaction. We have no access to them.
4. Managing cookies
Your browser can block or delete cookies. Blocking the strictly necessary ones will prevent signing in to your account area.
