Data protection

My websites do not collect, process, use or share any of your personal data.

However, my server logs contain data, which can be considered personal. In particular:

  • the IP address of the requesting client,
  • the date and time of the access,
  • the type of the request,
  • the status of the request,
  • the amount of transferred data, and
  • the user agent of the client (which contains information about the browser and the operating system).

The log files are kept for security reasons and are deleted after a maximum of 7 days. The information in these logs can be evaluated for statistical purposes, but you as an individual will remain anonymous.

On some of my pages, I use maps from OpenStreetMap or When you visit these web pages, your IP address will be transferred to the provider of the map. To my knowledge, the IP address is only used for the display of the particular map.

My websites are hosted by Hetzner.
