Your choice
The first time you visit, we ask whether statistics and marketing tools may be used. Nothing is loaded before you answer, and “Only necessary” is as easy to choose as “Allow all”. You can change your mind at any time:
We ask again after six months.
What is used
| Group | Tool | What it does |
|---|---|---|
| Necessary | Our own note of your choice | Remembers what you answered in the cookie notice, in your browser’s storage. No identifier, nothing sent to us. |
| Statistics | Google Analytics | Counts visits and pages, and shows which site or campaign visitors came from. Sets cookies beginning with _ga. |
| Statistics | Microsoft Clarity | Shows how pages are used (scrolling, clicks) so that we can improve them. Text typed into forms is masked. |
| Marketing | Google Ads | Tells us whether a click on one of our advertisements led to a trial request. |
| Marketing | Meta pixel, LinkedIn Insight Tag | The same for advertisements on Facebook, Instagram and LinkedIn. |
A tool appears here because the site is able to use it; whether it is in use at a given time depends on the campaigns we run. None of them is ever loaded without your agreement.
The test and the school portal
The pages on which candidates take a test and schools sign in use only what they need to work: a cookie that keeps a test or a sign-in open. They carry no statistics or advertising tools.
