Audience measurement
Since 23 September 2026, this site measures its traffic using three tools. The first deposits no cookies and operates without your agreement. The other two deposit cookies and only load after you accept them. As long as you have not accepted, or if you refuse, none of their cookies are written and no data is transmitted to them.
| Tool | What it measures | Consent | Duration |
|---|---|---|---|
| Cloudflare Web Analytics | Pages viewed and the site you arrived from. No cookies, no identifier retained between visits. | Not required | No cookies |
| Google Analytics 4 | Pages viewed, visit duration, country, and the site you arrived from. Your IP address is truncated before recording. Google's advertising features are disabled. Your data serves neither targeting nor personalization of ads. | Required | Cookies 13 months |
| Microsoft Clarity | Areas of the page you view and your navigation path, shown as anonymous replay. | Required | Session cookies |
Google Analytics 4 and Microsoft Clarity are edited by American companies. Data transferred to them is covered by adequacy between the European Union and the United States, in effect since 10 July 2023.
Your preferences
You can accept or refuse audience measurement subject to consent, and change your choice at any time from this page. Refusing takes nothing away from how the site works.
We would like to enable audience measurement to improve this site. It only starts with your agreement.
Your choice is kept for six months. After this period, you will be asked again.
