Legal information
Cookies and audience measurement
What we place on your device, what we measure, and how to refuse.
This text is a skeleton written during the development of the platform. The clauses on Vena Tokens, the right of withdrawal and account deletion were reviewed by a lawyer on 3 August 2026; the rest of the document was not, and several legal facts are still missing. As it stands, it constitutes neither a contractual commitment nor an enforceable document.
Every “[TO BE COMPLETED]” marker flags a legal fact that does not exist yet (company name, registration, host, providers). They will be filled in before any real launch.
01
What we are talking about
A cookie is a small file placed by a site on your device to keep an item of information between two pages. Some are essential to a service — remembering that you are signed in, for instance — others measure audience, and others follow you from site to site for advertising purposes.
We only use the first two categories, and the second one can be refused.
02
Strictly necessary cookies
They cannot be disabled: without them, signing in or switching language would not work. They serve no measurement purpose and are shared with no one.
- vl_refresh: keeps your session open without asking for your password again. Unreadable by page code, limited to authentication calls, revocable at any time by signing out.
- vl_session: tells the interface that a session exists, so as not to show an empty screen before redirecting. It contains no data and grants access to nothing.
- NEXT_LOCALE: remembers the language you chose.
- vl-measurement: records your decision on audience measurement. It contains only that decision and the version of the text you read — no identifier, no date, no fingerprint.

Our audience measurement
It is performed by our own servers, with no third-party tool and no advertising network. It records navigation events — page viewed, step reached in a track, origin of the visit — linked to a random identifier that is tied neither to your name nor to your email address.
It exists to know which pages are actually useful and where journeys fail. It feeds no advertising profile, is sold to no one and does not leave our servers.
The exact legal qualification of this measurement — exempt from consent, or subject to consent — is being validated. Until it is settled, we apply the most protective rule: nothing is measured before your agreement.
04
No third-party tracker
No advertising network, no social network and no external measurement tool sets a cookie on this site. No font, script or image is loaded from a third-party domain: everything is served from our own servers.
That is a technical choice as much as a privacy one: a resource loaded from a third party hands your network address to that third party, even without a cookie.
05
The “do not track” signal
If your browser sends the “Do Not Track” signal, we measure nothing, we ask you nothing and no banner appears. The signal is read on each visit: nothing is stored on your device to remember it.
That is the simplest behaviour, and the only coherent one: asking again through a banner when someone has already answered at browser level is pretending not to have heard.
06
Managing your choice
Your decision can be changed below, both ways, at any time, with no consequence on your use of the service: nothing is degraded, nothing is hidden, no feature is withdrawn if you refuse.
You can also delete this site's cookies from your browser settings. Deleting the decision cookie will make the banner appear again on your next visit.
Reading your choice…
