We attach great importance to the protection of your data and the protection of your privacy. This statement describes how and for what purpose your data is collected and used and what choices you have in connection with personal data.

What is personal data? This term is defined in the Federal Data Protection Act (BDSG) and the EU Basic Data Protection Regulation (DSGVO). Accordingly, this is data which can be assigned to a specific or identifiable person and which provides insight into their physical, physiological, economic, cultural or social identity (Article 4 No. 1 DSGVO). For example, this includes your civil name, your date of birth, health data, your address, your telephone number, your email address or online data such as your IP address.

The collection and processing of your personal data takes place in compliance with the applicable data protection regulations, in particular the EU Data Protection Basic Regulation (DSGVO). We collect and process your personal data in order to be able to offer you the above-mentioned portal. By using this website, you consent to the collection, use and transfer of your data in accordance with this privacy policy.

The following privacy policy applies to the use of the website (hereinafter “Website”).

2. General use of the website

2.1 Access data (server log files)

When you use our website, general information about your use and interaction with us is automatically collected. This information (so-called access data or server log files) includes the name and URL of the retrieved file, date and time of the retrieval, transferred data volume, notification of successful retrieval (HTTP response code), browser type and browser version, operating system, referrer URL (i.e. the previously visited page), IP address and the requesting provider.

We do not use these general log data to draw conclusions about your person. The purpose of recording the server log files is, among other things, statistical evaluations for the purpose of operation, security and optimisation of our online services, but also for anonymous recording of the number of visitors to our website (traffic) and the scope and type of use of our website and services. On the basis of this information, we can provide personalised and location-related content and analyse data traffic, search for and correct errors and improve our services. We reserve the right to subsequently check the log data if there is a justified suspicion of illegal use on the basis of concrete indications. We store IP addresses in the log files for a limited period of time if this is necessary for security purposes or for the provision or billing of a service, e.g. if you use one of our services.

2.2 Cookies

Our website uses so-called “cookies”. Cookies are small text files that are stored on your computer system and make it possible to store certain information about your usage behaviour. This includes data such as your IP address, the browser used and your operating system. With these cookies we can make it easier for you to navigate the website, increase user-friendliness and ensure that our website runs optimally and smoothly. Some of these cookies are so-called “session cookies”, which are deleted after the browser session. Others remain on your system and allow us to recognize you the next time you visit our website.

Of course you can refuse the use of cookies at any time. If you wish to use our or other websites without cookies, you can also set your Internet browser (Google Chrome, Mozilla Firefox, Internet Explorer or similar) so that it does not accept cookies. You can find out how this works in the user manual of your browser.

2.3 Google Analytics

We use Google Analytics, a web analysis service provided by Google Inc. (“Google”). Google Analytics uses “cookies”, which are text files placed on your computer, to help the website analyze how users use the site. The information generated by the cookie about the use of this website by website visitors is generally transmitted to a Google server in the USA and stored there.

However, if IP anonymisation is activated on this website, your IP address will be shortened by Google in advance within member states of the European Union or in other signatory states to the Agreement on the European Economic Area. Only in exceptional cases will the full IP address be transmitted to a Google server in the USA where it will be shortened. IP anonymization is active on this website. Google will use this information on our behalf to evaluate your use of the website, to compile reports on website activity and to provide us with other services relating to website activity and internet usage. For this purpose, we have concluded a contract with Google for order data processing.

The IP address transmitted by your browser as part of Google Analytics is not combined with other data from Google.

Details on the handling of user data by Google Analytics can be found in Google’s privacy policy:

For reasons of transparency, we would like to point out that we use the Google Tag Manager. The Google Tag Manager itself does not collect any personally identifiable information. The Tag Manager makes it easier for us to integrate and manage our tags. Tags are small pieces of code used, among other things, to measure traffic and visitor behavior, capture the impact of online advertising and social channels, set up remarketing and targeting, and test and optimize websites. We only use Google Analytics and DoubleClick. If you have made a opt-out, the Google Tag Manager will take that opt-out into account. For more information about the Google Tag Manager, please visit:

To draw attention to our services, we place ads on Google AdWords. These are displayed on Google after search queries. In the area of our contact forms, cookies are used to register how many users have found us via one of our ads. The resulting anonymous statistics enable us to optimize our ads. The cookie is stored by Google when you click on an advertisement and can be prevented via the settings of your browser In this case, your visit to our website will not be included in the anonymous user statistics.
