With this data protection declaration, users receive information about the type, scope and purpose of the collection and use of their data collected and used by the responsible provider.
The legal framework for data protection is provided by the German Federal Data Protection Act (BDSG) and the German Telemedia Act (TMG).

Collection of general information

With each access to this website, information is automatically collected by us or the web space provider. This information, also known as server logfiles, is of a general nature and does not allow any conclusions to be drawn about your person.
Among other things, the following are recorded: Name of the website, file, date, data volume, web browser and web browser version, operating system, the domain name of your internet provider, the so-called referrer URL (the page from which you accessed our website) and the IP address.
Without these data it would be technically impossible to deliver and display the contents of the website. In this respect, the collection of data is absolutely necessary. In addition, we use the anonymous information for statistical purposes. They help us to optimise our offer and technology. We also reserve the right to check the log files if there is suspicion of illegal use of our offer.


If you subscribe to our newsletter, we will use the data you have entered exclusively for this purpose or to inform you about the circumstances relevant for this service or registration. We do not pass these data on to third parties.
A valid e-mail address is required to receive the newsletter. The IP address used to register for the newsletter and the date on which you subscribe to the newsletter are also saved. This data serves as proof in case of misuse if a foreign e-mail address is registered for the newsletter. In order to ensure that an e-mail address is not misused by third parties in our distribution list, we use the so-called “double opt-in” procedure in accordance with the law. Within the framework of this procedure, the order of the newsletter, the sending of the confirmation mail and the receipt of the registration confirmation are recorded.
You have the possibility at any time to revoke your consent to the storage of your data, your e-mail address and their use for sending newsletters. For revocation, we provide you with a link in every newsletter and on the website. You also have the option of notifying us of your cancellation request via the contact details in this document.

Contact form

If you contact us via the online form or by e-mail, we store the information you provide in order to be able to answer your enquiry and ask possible follow-up questions.


This website uses so-called cookies. These are text files that are stored on your computer from the server.

Cookies fulfil two main tasks. They help us to make it easier for you to navigate through our offer and enable us to display the website correctly. They are not used to infiltrate viruses or start programs.
Users have the possibility to access our website without cookies. To do this, the appropriate settings must be changed in the browser.

Facebook Social Plug-in

We include plug-ins of the social network Facebook (address: 1601 South California Avenue, Palo Alto, CA 94304, USA) on our websites. You can recognize the plug-ins – you can find an overview here: – by clicking on the Like button (I like it) or the Facebook logo.
If you call up one of our websites with Facebook Plug-in, a direct connection to Facebook will be established. We have no influence on the type and extent of data collected, stored and processed by Facebook. We can only inform you according to our knowledge.
Facebook will be informed via the plug-in that you have visited the corresponding website of our offer. This also applies to users who are not registered with Facebook. In this case, Facebook may store the IP address.
If you are a Facebook member and you are logged in, accessing a website with Facebook Plug-in can be uniquely mapped to your Facebook account. In addition, the plug-ins transmit all interactions if you use the Like button or leave a comment, for example.
To prevent Facebook from storing information about you, please log out of Facebook before visiting our website. You can also block the plug-ins with browser add-ons (for example, ”Facebook Blocker”).

Data economy

We store personal data in accordance with the principles of data avoidance and data economy only for as long as it is required or prescribed by law (legal retention period).

Changes to our Privacy Policy

In order to ensure that our data protection declaration always complies with current legal requirements, we reserve the right to make changes at any time. This also applies if the data protection declaration has to be amended due to new or revised services, for example new services. The new data protection declaration will then take effect the next time you visit our website.
