This cookie contains a unique, pseudonymized visitor ID internal to Matomo for recognizing repeat visitors.

The _pk_id is an ID that makes it possible to verify which routes a website visitor has clicked on. A generated identifier is used for this purpose. On the basis of this ID, http requests can be linked to each other and corresponding statistics can be generated on e.g. B. the number of visits, average time a user stays on the website and the number of pages read.

This cookie is used to track from which website the anonymized user proceeded to any page or sub-page. The respective URL is saved as a string, which specifies the referrer, or rather the website from which the respective page was accessed, in a cookie to be able to create and analyze corresponding statistics.

The Matomo session cookie is used to track the visitor's page requests during the session. The cookie is automatically deleted at the end of each session (website visit), at the latest after one day. It is not possible to identify individuals using these cookies. The cookies are used to compile user statistics that cannot be directly tied to individuals (“pseudonymous usage profiles”).
