This page explains the cookies and similar technologies used on this website, what they are for, and how you stay in control of them. For full details of how we process data, see also our privacy policy.
What is a cookie?
A cookie is a small file placed on your device when you visit a website. It can, for example, remember your preferences or measure traffic. We also use your browser’s local storage, which works in a similar way. On this page, the word “cookie” covers both.
The cookies we use
Strictly necessary
Always on, with no tracking. They are essential for the website to work properly and are stored in your browser:
- remembering your choice in the consent banner, so we don’t ask you again on every page;
- remembering your display preference (light or dark theme);
- remembering the language of the site you last read (cookie
infrapro_lang), so the main address opens in that language; - a first-visit marker, cleared when you close your browser, so the welcome animation doesn’t replay on every page.
The booking form is protected against automated submissions by Cloudflare Turnstile, which checks technical signals from your browser, with no advertising tracking. The domain checker on the home page queries Cloudflare’s public DNS service from your browser, without setting any cookie. Fonts are hosted on our own site. If the booking form cannot load, the page shows the Microsoft Bookings booking page instead, which sets its own technical cookies.
Subject to your consent
These cookies are only set once you have accepted: until you choose, none of them is active. They are loaded by Google Tag Manager, which itself only loads once you agree.

Managing your cookies
On your first visit, a banner asks you to accept or decline these tools. You can change your mind at any time using the “Manage cookies” button at the bottom of every page. If you withdraw your consent, the tools are no longer loaded on your next visits; cookies already set can be deleted in your browser settings.
You can also set your browser to block or delete cookies. The CNIL offers advice on how to do this at cnil.fr. Please note that blocking strictly necessary cookies may affect how the website works.
How long cookies are kept
Your consent choice and display preference stay in your browser until you change them or clear your browsing data. The language preference lasts twelve months. Cookies subject to your consent last for the periods shown above, up to thirteen months.
