Analytics — Matomo
This site uses Matomo, a privacy-focused, self-hosted analytics tool, to understand how visitors use the site (page views, traffic sources, device types, etc.).
Matomo is hosted on our own infrastructure (matomo.nas.dewwwe.com). No analytics data is sent to any third-party service. Matomo is only activated if you explicitly accept cookies via the consent banner.
If you decline cookies, no analytics data is collected and no Matomo scripts are loaded.
Legal Basis for Processing
The legal basis for analytics data processing is your consent (Article 6(1)(a) of the GDPR). You can withdraw your consent at any time by clearing your browser cookies.

When you accept cookies, the following data may be collected anonymously:

- Browser type and version
- Device type (desktop, mobile, tablet) and screen resolution
- Referring website (where you came from)
