Cookie policy
What this site stores on your device. The short answer is almost nothing.
Last updated: August 2026
This site uses no cookies
We set no analytics cookies, no advertising cookies and no social cookies. There is no Google Analytics, no Tag Manager, no Facebook pixel and no embedded social buttons. The fonts come from our own server, so opening a page triggers no third party request at all.
Why you see no banner
Article 22.2 of the LSSI-CE requires consent when a site stores or reads information on your device. Nothing is stored and nothing is read here, so there is nothing to consent to. A banner asking permission for nothing is just in the way.
No local storage either
We use neither localStorage nor sessionStorage. The one thing that outlives the open page is the calculator's answers: they are written into the web address so you can share your estimate, so they stay in your browser history until you clear it. Your contact details are never written there.
When you leave the site
The WhatsApp buttons take you to a third party service. What happens there is governed by WhatsApp's cookies and privacy policy, not ours.
Controlling cookies yourself
You can block or delete cookies in your browser settings whenever you like. You will notice no difference on this site, because it does not rely on them.
If this changes
If we ever add analytics or any tool that needs cookies, we will publish the list here with its purpose and its lifetime, and we will show a real consent banner with non-essential cookies off by default and rejecting them as easy as accepting. Nothing will run before that.
