Integration of third-party services and content

It may happen that third party content, such as videos from YouTube, maps from Google Maps, RSS feeds or graphics from other websites are integrated within this online offer. This always requires that the providers of this content (hereinafter referred to as “third-party providers”) perceive the IP address of the users. Because without the IP address, they could not send the content to the browser of the respective user. The IP address is thus required for the display of this content. We endeavor to use only such content whose respective providers use the IP address only for the delivery of the content. However, we have no influence if the third-party providers store the IP address, e.g. for statistical purposes. Insofar as this is known to us, we inform the users about it.

We process connection data and browser data with our processor Fontawesome, Fonticons, Inc, 6 Porter Road, Apartment 3R, Cambridge, MA 02140, USA, for the purpose of providing the fonts required by the web browser to display the website. This data is only processed for the duration required for the selection and transmission of the fonts. The legal basis for the data processing is the legitimate interest (absolute technical necessity for the provision and delivery of the service (“website”) expressly requested by you by your call) pursuant to Art. 6 para. 1 lit. f DSGVO.

To the extent that any further independent processing of the data is carried out by Font Awesome, Fontawesome shall be the sole responsible party for such processing. For details, see Font Awesome’s privacy policy.

Use of social media plug-ins

We use the following social media plug-ins on this website:



We use the so-called “two-click solution” for this. This means that when you visit our site, initially no personal data is transmitted to the providers of the plug-ins. You can recognize the provider of the plug-in by the mark on the box above its initial letter or by the logo. We thus open up the possibility for you to communicate directly with the provider of the plug-in via the button. Only if you click on the marked field and thereby activate it, the plug-in provider receives the information that you have called up the corresponding website of our online offer. By activating the plug-in, personal data is transmitted from you to the respective plug-in provider and stored there.

We have no control over the data collected and data processing operations, nor are we aware of the full extent of the data collection, the purposes of the processing, the storage periods. We also have no information about the deletion of the collected data by the plug-in provider.

The plug-in provider stores the data collected about you as usage profiles and uses them for purposes of advertising, market research and / or needs-based design of its website. Such an evaluation is carried out in particular (also for users who are not logged in) for the display of tailored advertising and to inform other users of the social network about your activities on our website. You have the right to object to the creation of these user profiles, whereby you must contact the respective plug-in provider to exercise this right. Through the plug-ins, we offer you the opportunity to interact with the social networks and other users, so that we can improve our offer and make it more interesting for you as a user. The legal basis for the use of the plug-ins is Art. 6 para. 1 p. 1 lit. f GDPR.

For more information on the purposes and scope of data collection and processing by the plug-in provider, please refer to the following privacy statements of these providers. There you will also receive further information about your rights in this regard and setting options for protecting your privacy.
