Use of Matomo (formerly called Piwik)

This website uses the open source web analysis service Matomo. Matomo uses technologies that make it possible to recognize the user across multiple pages with the aim of analyzing the user patterns. The information recorded by Matomo about the use of this website will be stored on our server. Prior to archiving, the IP address will first be anonymized.

Through Matomo, we are able to collect and analyse data on the use of our website by website visitors. This enables us to find out, for instance, when which page views occurred and from which region they came. In addition, we collect various log files (e.g. IP address, referrer, browser, and operating system used) and can measure whether our website visitors perform certain actions (e.g. clicks, purchases, etc.).

The use of this analysis tool is based on Art. 6 Sect. 1 lit. f GDPR. The website operator has a legitimate interest in the analysis of user patterns, in order to optimize the operator’s web offerings and advertising.


We host Matomo by an external service provider (host). Personal data collected on this website are stored on the servers of the host. Our host will only process your data to the extent necessary to fulfil its performance obligations and to follow our instructions with respect to such data.
