On behalf of the provider of this website, Google will use this information to analyze the usage of this website, to generate reports on the website activities and to provide services related to the website or internet use to the website provider. The IP address transmitted from your browser with Google Analytics is not merged with other data from Google.

Use of script libraries (Google Webfonts)

We use script and font libraries like Google Webfonts on our website to correctly display our contents across browsers ( Google Webfonts are transferred to your browser to avoid multiple writing to the cache. If the browser does not support Google web fonts or denies access, the content is shown in a standard font.

Accessing script or font libraries will automatically create a connection to the library provider. Theoretically, library providers may also store data. It is not certain whether they do and, if so, what for.

Embedded YouTube videos

On some of our websites we have embedded YouTube videos. The plug-in provider is YouTube, LLC, 901 Cherry Ave., San Bruno, CA 94066, USA. When you access a website with a YouTube plug-in, you will be connected with servers from YouTube. This informs YouTube of which sites you are visiting. When you are logged in with your YouTube account, YouTube can relate your surf behavior to you personally. You can prevent this by logging out of your YouTube account beforehand.

When a YouTube video is started, the provider uses cookies to get information on the user behavior.

Deactivating cookies for the Google Ad program will prevent this. YouTube also stores non-personal information on the use of their sites in other cookies. You can prevent this by blocking the storage of cookies in your browser.

Social Plug-ins

On our website, we use social plug-ins of the below mentioned providers. All plug-ins are marked by a corresponding logo and can easily be recognized.

These plug-ins may transmit information including personal data to the service provider who might make use of them. We prevent the unconscious and unwanted collection and transfer of data to the service provider by a 2-click solution. To activate a desired plug-in, click on the corresponding button. Activation of the plug-in starts the collection and transmission of information to the service provider. We do not collect personal data by social plug-ins or their use ourselves.

We have no influence on the data collected by an activated plug-in and used by the provider. At the time, we must assume that a direct connection is established to the service provider and that at least the IP address and device-related information is collected and used. There also is a possibility that service providers try to store cookies on the used computer.  Get information on the actual data collected and how they are used in the service providers’ privacy statements.
