Use of Google Maps

On our site we use "Google Maps" of the company Google Ireland Ltd, Google Building Gordon House, 4 Barrow St, Dublin, D04 E5W5 in Ireland, hereinafter referred to as "Google".

Each time "Google Maps" is called up, Google sets a cookie to process user data and user settings when the page on which "Google Maps" is integrated is displayed. This cookie is not deleted when the browser is closed, but expires after a certain time, unless you delete it manually beforehand.

If you do not agree with this processing of your data, you have the possibility to deactivate the service of "Google Maps" and thus prevent the transmission of data to Google. To do so, you must deactivate the Java-Script function in your browser. We would like to point out, however, that in this case you will not be able to use "Google Maps", or only to a limited extent.

For the use of "Google Maps" and the information obtained via "Google Maps" the following Google terms of use as well as the additional terms and conditions for "Google Maps" apply.

Use of reCAPTCHA

We protect input forms on our site by using the "reCAPTCHA" service provided by Google Ireland Ltd., Google Building Gordon House, 4 Barrow St, Dublin, D04 E5W5 in Ireland, hereinafter referred to as "Google". By this use it can be distinguished whether the corresponding input is of human origin or whether it is misused by automated machine processing.

To the best of our knowledge, the referrer URL, the IP address, the behaviour of the website visitors, information on the operating system, browser and duration of stay, cookies, display instructions and scripts, the input behaviour of the user as well as mouse movements in the "reCAPTCHA" checkbox area are transmitted to "Google".

Google uses the information obtained in this way to digitize books and other printed matter and to optimize services such as Google Street View and Google Maps (e.g. house number and street name recognition).

The IP address transmitted within the scope of "reCAPTCHA" is not merged with other data from Google unless you are logged into your Google account at the time of using the "reCAPTCHA" plug-in. If you wish to prevent this transmission and storage of data about you and your behavior on our website by "Google", you must log out of "Google" before you visit our site or use the "reCAPTCHA" plug-in.

If you have reached our website via a Google display, a cookie will be placed on your computer. Cookies are small text files that your internet browser places and stores on your computer.

If you visit certain pages of our website and the cookie has not expired, we and Google can recognize that you as a user clicked on one of our ads placed at Google and were redirected to our site.

The information collected through the "conversion cookies" is used by Google to compile visit statistics for our site.
