We adhere to the principles of data avoidance and data minimisation. We therefore only store your personal data for as long as is necessary to achieve the purposes stated here or as stipulated by the various storage periods provided for by law.

This information (server log files) includes, for example, the type of web browser, the operating system used, the domain name of your internet service provider and similar. This is exclusively information that does not allow any conclusions to be drawn about your person.

This information is technically necessary in order to correctly deliver contents of websites accessed by you and is compulsory when using the internet. In particular, it is processed for the following purposes:

  • ensuring a smooth connection of the website,
    • ensuring smooth use of our website,
    • evaluating system security and stability, and
    • other administrative purposes.

Processing of your personal data is based on our legitimate interest in connection with the aforementioned data collection purposes. We do not use your data to draw conclusions about your person. The only recipients of the data are the controller and, if applicable, processors.
Anonymous information of this kind may be statistically evaluated by us in order to optimise our website and the technology behind it.

Like many other websites, we also use so-called “cookies”. Cookies are small text files that are transferred from a website server to your hard drive. This automatically provides us with certain data such as IP address, browser used, operating system and your connection to the internet.

Cookies cannot be used to run programs or deliver viruses to a computer. The information contained in cookies allows us to facilitate your navigation and enable the correct display of our websites.

Embedded YouTube videos
We embed YouTube videos on some of our websites. The operator of the corresponding plug-ins is YouTube, LLC, 901 Cherry Ave, San Bruno, CA 94066, USA. When you visit a page with the YouTube plug-in, a connection to YouTube servers is established. This informs Youtube which pages you are visiting. If you are logged into your YouTube account, YouTube can allocate your surfing behaviour to you as an individual. You can prevent this by logging out of your Youtube account first.

If a Youtube video is started, the provider uses cookies that collect information about user behaviour.

If you have deactivated the storage of cookies for the Google Ad programme, no such cookies can be expected when watching Youtube videos. However, Youtube also stores non-personal usage information in other cookies. If you wish to prevent this, you must block the storage of cookies in your browser.

Further information on data protection at “Youtube” can be found in the provider’s data protection declaration at:
