5. Analytics tools

a) Tracking tools

The tracking measures that we use and which are listed below are deployed on the basis on Art. 6 (1) sentence 1 f) GDPR. With the tracking measures used, we want to ensure the needs-based design and continuous optimisation of our website. Conversely, we use the tracking measures to statistically record the use of our website and evaluate it for the purpose of optimising our website for you. These interests are to be regarded as justified within the meaning of the aforementioned provision.

The respective data processing purposes and data categories can be found in the corresponding tracking tools.

i) Google Analytics

In order to design and continuously optimise our website as required, we use Google Analytics, a web analytics service provided by Google Inc. ( (1600 Amphitheatre Parkway, Mountain View, CA 94043, USA; hereinafter referred to as "Google"). In this context, pseudonymized usage profiles are created and cookies (see point 4) are used. The information generated by the cookie regarding your use of the website such as

  • browser type/version, operating system used,
  • referrer URL (the page previously visited),
  • the host name of the accessing computer (IP address),
  • the time of the server request is,

as a rule, transmitted to and stored by Google on servers in the United States. Google will use this information to evaluate your use of the website, compile reports on website activity and provide other services relating to website activity and Internet usage and services related to Internet use for the purpose of market research and the needs-based design of these web pages. This information may also be transferred to third parties if required by law or if third parties process this data on behalf of Google. In no event will your IP address be associated with other Google data. The IP addresses are anonymized, so that they cannot be assigned to a specific person (IP masking).

You may refuse the installation of cookies by selecting the appropriate settings on your browser. However, please note that if you do this, you may not be able to use the full functionality of this website.

Furthermore, you can prevent Google’s collection and use of data relating to your use of the website (incl. your IP address) by downloading and installing the browser plug-in available under the following link

As an alternative to the browser add-on, especially for browsers on mobile devices, you can also prevent data being collected by Google Analytics by clicking on "Deactivate Google Analytics". An opt-out cookie will be set on the computer, which prevents the future collection of your data when visiting this website. The opt-out cookie is only valid on this browser and only for our website and is stored on your device. If you delete the cookies on this browser, you have to set the opt-out cookie again.

For more information about privacy related to Google Analytics, go to the Google Analytics Help Centre (

ii) Google Adwords conversion tracking

In order to statistically record the use of our website and to evaluate it for the purpose of optimising our website, we also use Google conversion tracking. In doing so, Google Adwords will set a cookie (see section 4) on your computer if you have reached our website via an ad placed by Google.

These cookies expire after 30 days and are not used for personal identification. If the user visits certain pages of the Adwords customer's website and the cookie has not yet expired, Google and the customer will be able to see that the user has clicked on the ad and has been redirected to this page.

Each Google AdWords customer receives a different cookie. Cookies can therefore not be traced through the websites of AdWords customers. The information collected using the conversion cookie is used to generate conversion statistics for Adwords customers who have opted for conversion tracking. Adwords customers can see the total number of users who clicked on their ad and were redirected to a page with a conversion tracking tag. However, they will not receive any information that personally identifies users.

If you do not wish to participate in the tracking process, you can also refuse the required setting of a cookie – e.g. via browser settings that generally deactivate the automatic setting of cookies. You can also disable cookies for conversion tracking by setting your browser to block cookies from the domain "". Google's privacy policy regarding conversion tracking can be found here: (

6. Google Maps

This website uses Google Maps to display interactive maps and generate directions. Google Maps is a map service operated by Google Inc., 1600 Amphitheatre Parkway, Mountain View, California 94043, USA. By using Google Maps, information about the use of this website (including your IP address and the (starting) address entered as part of the route planner function) may be transmitted to and stored by Google on servers in the United States. When you visit a web page on our website that contains Google Maps, your browser establishes a direct connection to Google's servers. The content of the map will be transmitted by Google direct to your browser and incorporated into the website by it. We therefore have no control over the extent of the data collected by Google this way. According to our knowledge, the following data, at the very least, are collected:

  • date and time of the visit to the website concerned,
  • the Internet address or URL of the website visited,
  • the IP address, based on the (starting) address entered during route planning.

We have no influence on the further processing and use of the data by Google and can therefore not accept any responsibility for this.

If you do not want Google to collect, process or use information relating to you via our website, you can disable JavaScript in your browser settings. In this event, however, you will not be able to use all the features of the maps displayed.

The purpose and scope of the data collection and the further processing and use of the data by Google, as well as your rights and settings for the protection of your privacy, can be found in the Privacy Policy of Google (

By using our website, you consent to the processing of data collected about you by Google Maps route planner in the manner of data processing and for the purposes set out above.

7. Google reCAPTCHA

We use "Google reCAPTCHA" (hereafter referred to as "reCAPTCHA") on our websites. The provider is Google Inc., 1600 Amphitheatre Parkway, Mountain View, CA 94043, USA ("Google").

By using reCAPTCHA, we want to verify if the data being entered on our websites (e.g. in a contact form) is being entered by a human or by an automated program. To this end, reCAPTCHA analyses the behaviour of the website visitors, using various characteristics. This analysis begins automatically, as soon as the website visitor enters the website. For the analysis, reCAPTCHA evaluates a range of information (e.g. IP address, dwell time of the website visitor on the website, or mouse movements made by the user). The data collected during the analysis are forwarded to Google.

ReCAPTCHA analyses run completely in the background. Visitors to the website are not informed that an analysis is taking place.

Data processing takes place on the basis of Art. 6 (1) f) GDPR. The website provider has a legitimate interest in protecting its web content from fraudulent automated spying and SPAM.

8. Google web fonts

This website uses so-called web fonts provided by Google for the uniform representation of fonts. When you open a page, your browser loads the required web fonts into your browser cache in order to display texts and fonts correctly.

For this purpose, your browser has to establish a direct connection to Google servers. This informs Google that our website was accessed via your IP address. Google web fonts are used to ensure a uniform and appealing presentation of our online offers. This constitutes a legitimate interest pursuant to Art. 6 (1) f) GDPR.

If your browser does not support web fonts, one of your computer's standard fonts will be used by your computer.
