      Except for the use of Google Fonts, Google Maps, and subsequently named companies, no personal information that we collect will be processed in any third country. These services are provided by Google LLC, 1600 Amphitheatre Parkway, Mountain View, CA 94043, USA.

      As concerns the use of Google Fonts and Google Maps, an appropriate level of data protection by Google Inc. will be provided as part of its participation in the ‘Privacy Shield’ and measures taken by Google on data protection and data security in the EU. See also the notes on Google Fonts and Google Maps.

      The following explanations provide an overview of third-party providers as well as their contents, including links to their privacy policies, which contain further notes on the processing of data and ways of opting out, some of which have already been mentioned here.

      Google Web Fonts

      We use web fonts provided by Google for the uniform representation of fonts. When you call up a page, your browser loads the required web fonts into your browser cache to display texts and fonts correctly. To do this, your browser must connect to Google’s servers. As a result, Google learns that our website has been accessed via your IP address. The use of Google Web Fonts is in the interest of representing our online services in a consistent and appealing way. The legal basis for this is Article 6(1)(f) GDPR.

      For more information about Google Web Fonts, see the Google Privacy Policy:
      You can set your browser so that the fonts are not loaded by Google’s servers (e.g., by installing add-ons). If your browser does not support Google Fonts or you block access to Google servers, the text will be displayed in the system default font. Please note that our page will then no longer display using our screen design.

      Google Maps

      We use the Google Maps map service via an API for the purpose of representing our online services in an appealing way and making it easy to locate the places we indicate on the website. The use of Google Maps requires your IP address to be stored. This information is usually transmitted to a Google server in the USA and stored there. The legal basis for this is Article 6(1)(f) GDPR.

      For more information on the handling of user data, please refer to Google’s Privacy Policy:

      If you disagree with the future transmission of your data to Google while using Google Maps, you may disable the Google Maps Web service entirely by turning off the JavaScript application in your browser, in which case Google Maps and the map display on this website can no longer be used. Please note that if JavaScript is disabled, other functions that we would like to offer you on our website will no longer function either.
