Google Maps

Our website uses Google Maps to display maps and to create directions. Google Maps is operated by: Google Ireland Limited, Gordon House, Barrow Street, Dublin 4, Ireland. Google Maps uses at least your IP address to be able to deliver up-to-date maps. If you specify a desired location display in more detail in a detection field on our site (e.g. location information), this non-personal information will probably be processed by Google in connection with the IP address that identifies you in more detail. We do not have any detailed knowledge of these processes. As an end user of the function, please inquire about this in the Google Maps Terms of Use.

Legal basis for data processing:

The collection and use of the automatically determined data and the data entered by you by Google takes place on the basis of your consent within the meaning of Article 6 (1) sentence 1 lit. a GDPR.

As part of the display of Google Maps, Google acts independently and is not bound on our behalf.

For the Google Maps Terms of Use, see Google Maps Terms of Use on our website. Full details can be found at:

Social media presence (LinkedIn and Twitter)

We maintain online presences within social networks in order to communicate with the users active there or to offer information about us there. The corresponding links (LinkedIn and Twitter) are integrated on our website and take you there directly.

If you call up a page on our website that contains such a button, your browser only establishes a direct connection to the LinkedIn and Twitter servers in the USA when you click on the button. If you are a participant at these social media providers and are logged in there, the providers can directly assign your visit to our website to your account. This information can be used for advertising, market research and needs-based design of the social media websites. For this purpose, usage, interest and relationship profiles are created by the providers, e.g. to evaluate your use of our website with regard to the advertisements displayed to you by the providers.

If you do not want the data collected via our website to be assigned to your account, you must log out of the provider before you visit our website.

The purpose and scope of the data collection and the further processing and use of the data by LinkedIn and Twitter as well as your rights in this regard and setting options for protecting your privacy can be found in the data protection information.

We would like to point out that LinkedIn and Twitter may process user data outside of the European Union. This can result in risks for users, for example because it could make it more difficult to enforce user rights.

In the case of requests for information and the assertion of data subject rights, we would like to point out that these can be asserted most effectively with the providers. Only the providers have access to the data of the users and can take appropriate measures and provide information directly. If you still need help, you can contact us.
