As the provider of this website I am legally obliged to inform you about the purpose, extent and nature of the collection and use of your personal data. Personal data is information about personal and factual circumstances of a specific or identifiable natural person.

The legal basis for the processing of user data is Article 6 paragraph 1 lit. f) of the DSGVO. This is the so-called data processing based on a balancing of interests. My interest is exclusively focused on the secure and functional operation of this website.

To give you a good feeling for the way in which we collect, process and use data, I would like to give you an overview of data processing. If you have any further questions, please feel free to contact me at any time.

When you visit my website, data is collected, processed and used. In detail, the following data record is stored with each access by your terminal device (PC or mobile phone):

  • IP address,
  • Operating system,
  • Browser version,
  • Name of the retrieved file,
  • Date and time of the retrieval,
  • transmitted data volume,
  • Referring URL.

The above data is stored in the files 'access_log' and 'error_log' on the web server. The log files are created to maintain the server operation without disturbances.

A technically necessary (session) cookie is set, which is automatically deleted at the end of the browser session.

IP address

In order for the pages to be displayed in your browser, the IP address must be collected and stored by the web server. Usually, an IP address is currently assigned dynamically by your provider. This address usually changes regularly, so that we ourselves cannot establish a personal reference from the IP address. In individual cases (e.g. with static IP addresses) the creation of a personal reference would be theoretically conceivable. However, we have no interest in establishing a personal reference and will not do so.

The IP address from the above-mentioned data record is anonymised after 24 hours by overwriting the last octet with zeros. The deletion will then take place after 7 days at the latest. With the deletion of the IP address, no personal reference is possible for us. The legal basis for the processing of this data - in this case the IP address - with regard to users of our Internet offer is also here Article 6 paragraph 1 lit. f) of the DSGVO. It is in our interest to ensure that the contents of our website are made available.

If you are only a user of our Internet site, I do not have any further personal data which I could assign to you and thus also provide information about you. There are neither interactive forms nor comment functions.

The legal basis for the processing of this data - in this case the IP address - with regard to users of our Internet offer is also here Article 6 Paragraph 1 lit. f) of the DSGVO. Our interest here is to ensure that the contents of our website are made available.

If you do not wish to receive cookies, you can deactivate the storage of cookies on your end device by changing the settings of your browser accordingly. Cookies already stored can be deleted in the system settings of the browser. The exclusion of cookies can lead to functional limitations of the Internet offer.

My internet offer contains links to internet offers of other providers. I have no influence on whether these providers adhere to the data protection regulations.


If you send me an e-mail, it will be saved by me until your request has been processed. I take care that the data is kept safe from unauthorized access by third parties.
