Collection and storage of personal data and how and why it is used

When you visit our website, the browser used on your device will automatically send information to our website server. This information is temporarily stored in a ‘log file’. As part of this, the following information is gathered without any action on your part and stored until it is automatically deleted:

  • IP address of the requesting computer,
  • date and time of access,
  • name and URL of the file accessed,
  • website from which our site is accessed (referrer URL),
  • browser used and optionally your computer’s operating system as well as the name of your access provider.

We process the data mentioned for the following purposes:

  • establishing a smooth connection to the website,
  • making our website easy to use,
  • evaluating the security and stability of our systems, and
  • for other administrative purposes.

The legal basis for the processing of data is Article 6(1)(f) of the General Data Protection Regulation (GDPR). Our legitimate interest derives from the data collection purposes listed above. Under no circumstances will we use the data collected to draw conclusions about you as an individual.

We also use cookies and analytics services when you visit our website. These terms are explained in more detail in points 4 and 5 of this data protection declaration.

Passing on data

Your personal data will not be transmitted to third parties for purposes other than those listed below.

We will only pass on your personal data to third parties if:

  • you have given your express consent for us to do so in accordance with Article 6(1)(a) GDPR,
  • passing on the data is necessary, in accordance with Article 6(1)(f), for the establishment, exercise or defence of legal claims and there is no reason to assume that you have an overriding legitimate interest in your data not being passed on,
  • in the event that there is a legal obligation to pass on the data in accordance with Article 6(1)(c) GDPR, and
  • this is legally permissible and necessary, in accordance with Article 6(1)(b) GDPR, for handling our contractual relationships with you.


We use cookies on our website. These are small data files which are automatically created by your browser and stored on your device (laptop, tablet, smartphone, etc.) when you visit our website. Cookies do not damage your device and they do not contain any viruses, Trojans or other harmful software.

The cookie stores information which arises in each case in connection with the specific device used. However, this does not mean that we are immediately informed of your identity.

First, using cookies helps us to make our service more convenient for you to use. For example, we use ‘session cookies’ to identify that you have already visited several pages on our website. These are automatically deleted when you leave our site.

In addition, we also use temporary cookies to optimise user-friendliness. These cookies are stored on your device for a certain set period of time. If you visit our site again to use our services, the fact that you have already visited will be automatically detected, along with the options and settings you selected, so that you do not need to enter these again.

Second, we use cookies to gather statistics about and evaluate the use of our website for the purpose of optimising our service for you (see point 5). When you visit our website again, these cookies allow us to automatically detect that you have already visited. These cookies will be automatically deleted after a defined period of time has passed in each case.

The data processed by cookies are necessary for the stated purposes in order to preserve our legitimate interests and those pursued by third parties in accordance with Article 6(1)(f) GDPR.

Most browsers automatically accept cookies. However, you can configure your browser not to store any cookies on your computer or to always show you a message before a new cookie is created. Fully disabling cookies may mean, however, that you are unable to use all of the functions of our website.

Analysis tools

a) Tracking tools

The tracking measures listed below and used by us are implemented on the basis of Article 6(1)(f) GDPR. The tracking measures used are intended to ensure a needs-based design and the continuing optimisation of our website. We also use the tracking measures to gather statistics about and evaluate the use of our website for the purpose of optimising our service for you. These interests are deemed legitimate within the meaning of the above-mentioned regulation.

The respective data processing purposes and data categories are set out for the corresponding tracking tools.

a.i) Google Analytics1

For the purpose of needs-based design and continuing optimisation of our websites, we use Google Analytics, a web analysis service from Google Inc. ( (1600 Amphitheatre Parkway, Mountain View, CA 94043, USA; hereinafter “Google”). This involves the creation of pseudonymised user profiles and the use of cookies (see point 4). The information generated by the cookie about your use of this website, such as

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

are transmitted to a Google server in the USA and stored there. The information is used to evaluate how the website is used, compile reports about the website activities and provide other services associated with the use of the website and the internet for the purposes of market research and needs-based design of these websites. This information may also be transmitted to third parties if required by law or if third parties process these data on its behalf. Under no circumstances will your IP address be combined with other data from Google. The IP addresses are anonymised, so no association is possible (IP masking).

You can prevent the installation of cookies by an appropriate setting in the browser software; however, in this case you may not be able to use all of the functions of this website in full.

You can also prevent the data created by the cookies and relating to your use of the website (including your IP address) from being collected and processed by Google by downloading and installing a browser add-on (

As an alternative to the browser add-on, particularly for browers on mobile devices, you can also prevent Google Analytics from collecting your data by clicking on this link. This will place an opt-out cookie, which will prevent your data being collected when you visit this website in the future. The opt-out cookie applies only in this browser and only for our website and is stored on your device. If you delete the cookies in this browser, you will have to install the opt-out cookie again.

You can find more information on safeguarding your data in connection with Google Analytics on the Google Analytics Help page, for example (

a.ii) Google Adwords Conversion Tracking

To gather statistics about and evaluate the use of our website for the purpose of optimising our website for you, we also use Google Conversion Tracking. This involves Google Adwords placing a cookie (see point 4) on your computer if you are directed to our website via a Google ad.

These cookies are no longer valid after 30 days and are not used for personal identification. If the user visits certain pages on the website of an Adwords customer and the cookie has not yet expired, Google and the customer can identify that the user has clicked on the ad and been directed to this page.

Each Adwords customer is given a different cookie. It is thus not possible to track cookies via the websites of Adwords customers. The information gathered by the conversion cookies is used to create conversion statistics for Adwords customers who have opted for conversion tracking. The Adwords customers can thus find out the total number of users who have clicked on their ad and been directed to a page provided with a conversion tracking tag. However, they do not receive any information which could be used to personally identify the users.

If you wish to opt out of the tracking process, you can also refuse the placing of a cookie which is required for this – for instance via a setting in your browser which disables the automatic placing of cookies in general. You can also disable cookies for conversion tracking by setting your browser in such a way that cookies from the domain “” are blocked. You can find Google’s privacy notice on conversion tracking here:

Data security
