You can visit and use our websites without any restriction. All your connections to this website are end to end encrypted to prevent misuse by third parties. However, our web server automatically stores some general technical information, for example about your web browser, the operating system, the screen resolution, the domain name of your Internet service provider and how, when and how long you stayed on our website. This data does not reveal personal information about you. We evaluate this data for statistical purposes only and all data remains exclusively anonymous.


Since the entry into force of the GDPR (General Data Protection Regulation) we use cookies and show you the hints towards them by an additional link to this privacy policy while you visit the website. However, you can easily refuse or limit cookies with the help of appropriate settings on your browser, this has no effect on the functionality of these websites.

External services

Google Analytics

Due to data protection, this website does not use and has never used Google Analytics services. As this is unusual, we would like to point this out to you.

Other used Google services

In some places on these pages we use Google Chart APIs to generate QR codes dynamically.

Other services of other external providers

Currently we do not use any other external services.

Analysis with Motomo / formerly Piwik

Due to data protection concerns regarding the use of Google services, in particular Google Analytics, we are currently testing Matomo software which has been developed with particular regard to anonymity and privacy concerns. Even here tracking cookies are used by the software and processed by our service provider („Data processor“) for us, but they do not leave the server. A simple „Do Not Track“ setting in your browser is enough to completely stop the tracking and thus the analysis of your website visit.

Assigned data usage

We adhere to the principle of earmarked data use and collect, process and store your personal data only for the purpose specified by you, for example to process a contract concluded with you or to answer your request. The data are stored in accordance with the legal requirements for the respectively prescribed duration. A transfer of your personal data away from the statutory provisions to third parties does not occur.
