Data Privacy

If the opportunity for the input of personal or business data (email addresses, name, addresses) is given, the input of these data takes place voluntarily. The use and payment of all services offered is - as far as technically possible and reasonable - also permitted without the provision of such data or by providing anonymous data or a pseudonym. The use of contact data published in the imprint or comparable information such as postal addresses, telephone and fax numbers and e-mail addresses by third parties for the purpose of sending information not expressly requested is not permitted. We expressly reserve the right to take legal action against the senders of so-called spam mails in case of violation of this prohibition.


Cookies are text files which are stored on your computer and which enable an analysis of your use of the website. For example, it is recorded in which browser or in which browser size you have visited a website.

On they are used to show the use of the website in a statistic and to enable me to improve the website accordingly. For this purpose I use Google Analytics, which is explained in more detail in the next section.

When you visit this website for the first time, you will be asked explicitly for your consent that you are aware of the use of cookies if you wish to continue using the website.

You may refuse the use of cookies by selecting the appropriate settings on your browser. As cookies are only needed on in connection with Google products and the commentary system Disqus (this will be explained in more detail in the next section), you can read and see the contents on despite the prevention of cookies.

Google Analytics uses Google Analytics (a web analytics service) from Google Inc. (“Google”). Google Analytics uses cookies (see above). The information generated by cookies about your use of this website (including your IP address) is transferred to a Google server in the USA and stored there. Google will use this information for the purpose of evaluating your use of the website, compiling reports on website activity for website operators (in our case for me) and providing other services relating to website activity and internet usage. Google may also transfer this information to third parties where required to do so by law, or where such third parties process the information on Google’s behalf. Google will not associate your IP address with any other data held by Google.

By using this website, you agree to the processing of the data collected about you by Google in the manner and for the purpose described above.

Disqus uses a comment system that you can find under most blog posts. You can comment by registering with Disqus or by logging in via one of the social media platforms available if you have an account there. Before commenting, you must agree to Disqus’ terms of use and privacy policy.

When I log in to Disqus to manage the comments left on, I am not shown the full email addresses. I only see the first letter of the email address as well as everything behind the @-sign and the @-sign itself.
