Collected data

Internet Protocol (IP) addresses are used to process web requests. Not anonymized IP addresses are also written to log files and usually deleted after a few days.

Anonymized IP addresses are collected and used for range measurements.

For this, also non-personally identifiable information provided by web browsers, for example, the browser type, preferred language, the referring site, and the date and time of each visitor request is collected.


For some website features (like language selection) cookies are required.

A cookie is a string of information that a website stores on a visitor's computer, and that the visitor's browser provides to the website each time the visitor returns.

They are deleted after they are not needed anymore.

For user convenience, the selected language cookie is stored for one month.


All servers processing and storing data are located in Germany and hosted by netcup GmbH.

The data collected will not be passed over to third parties except if this is required by law.
