Cookies and tracking technologies
Last updated : 2026-08-27 · Version 2026-08-27.1
This site uses no social network pixel, no third-party analytics tool and no data broker. Only two mechanisms collect information during your visit, plus one cookie strictly necessary for signing in. Each is controlled separately, on this page.
Internal audience measurement
We record the pages you view during your visit under an anonymous identifier that dies with your tab. No cookie is set and nothing is sent to a third party. You can turn it off here: your choice is kept on this device.
Strictly necessary cookie — client area sign-in
Set only when you sign in to the client area. It carries an opaque session identifier, revocable server-side, sent only over HTTPS and inaccessible to page scripts. It keeps you signed in and measures nothing. It cannot be refused without giving up signing in, since it is what carries the session. You get rid of it by signing out.
Internal audience measurement — can be turned off below
We record the pages viewed during your visit under an identifier created by your browser and kept in session storage: it DIES with your tab, and the same visitor returning tomorrow is not recognised. No cookie is set and nothing is sent to a third party. We also keep the landing page, the referring site, the language and, where present, the campaign parameters in the address you arrived through. That identifier only becomes linkable to you if you submit a form yourself.
Google Ads measurement — subject to your acceptance
If you accept it, Google may set a cookie to measure which Google Ads bring real requests. Until you have chosen, NO Google script is loaded and nothing goes to Google. What is sent when you accept: the fact that a request was submitted, and an internal technical identifier. Never your name, your email, your number, or the content of your message. You can change your mind at any time through the "Cookies" link at the bottom of every page; refusing is as accessible as accepting, and the absence of a choice counts as a refusal.
No geolocation
The site never asks for your location and uses no geolocation technology. That permission is denied site-wide by a permissions policy served on every page, alongside camera and microphone.
