Purposes of data processing by the data controller and third parties

We process your personal data only for the purposes stated in this data protection declaration. We do not transfer your personal data to third parties for purposes other than those stated. We only pass on your personal data to third parties if:

  • You have given your express permission to do so,
  • The processing is necessary to conclude a contract with you,
  • The processing is necessary to fulfil a legal obligation,
  • The processing is necessary to safeguard legitimate interests and there is no reason to assume that you have an overriding legitimate interest in the non-disclosure of your data.

Erasure or blocking of data

We abide by the principles of data avoidance and data economy. We therefore only store your personal data for as long as necessary to achieve the objectives stated here or for as long as necessary to comply with the various data retention periods laid down by law. After the purpose has ceased to apply or these periods have expired, the corresponding data are routinely blocked or deleted in accordance with the statutory provisions.

Collection of general information on visiting our website

When you access our website, information of a general nature is automatically collected by means of a cookie. This information (server log files) includes the type of web browser, the operating system used, the domain name of the internet service provider and the IP address used.

This information is technically necessary in order to correctly deliver the contents of websites requested by you and is mandatory when using the internet. It is processed in particular for the following purposes:

  • Ensuring the problem-free connection of the website,
  • Ensuring the smooth utilisation of our website,
  • Evaluating system security and stability, and
  • For other administrative purposes.

The processing of your personal data is based on our legitimate interest due to the aforementioned purposes of data collection. We do not use your data to draw conclusions about your person. The only recipients of the data are the data controller and, if applicable, the processors.

We may subject anonymous information of this kind to statistical analysis in order to optimise our website and the technology behind it. The website operator reserves the right to subsequently check the server log files, in particular the IP address, if there are concrete indications of illegal use. 

The legal basis for the temporary storage of the data and the log files is Article 6 Para. 1 (f) GDPR.


Like many other websites we use “cookies”, small text files from a website server that are saved on your hard drive. Their use means we automatically receive certain data, e.g. IP address, browser type, operating system and your internet connection.

Cookies cannot be used to start programmes or transmit viruses to a computer. The information contained in cookies allows us to facilitate navigation and ensure our website is displayed correctly.

We never disclose the data we collect to third parties or associate it with personal data without your consent.

Of course, if you so wish, you can view our website without using cookies. Web browsers are normally set to accept cookies. In general, you can deactivate cookies at any time by changing your browser settings. Please use your browser’s help function to find out how to change these settings. Please note that certain functions on our website may not work if you deactivate the use of cookies.

SSL encryption

In order to ensure that your data remains secure during transmission, we use state-of-the-art encryption methods (e.g. SSL) via HTTPS.

Contact form

If you contact us with questions of any kind by sending an email or using the contact form, you give us your voluntary consent to contact you. For this purpose, it is necessary to provide a valid e-mail address. This is used to assign the enquiry and the subsequent response to it. The provision of further data is optional. The information you provide will be stored for the purpose of processing the enquiry and for possible follow-up questions. Personal data will be automatically deleted after your enquiry has been dealt with.

Changes to our data protection policy

We reserve the right to adapt this data protection policy so that it always complies with the current legal requirements or so that changes to our services are reflected in the data protection declaration, e.g. when introducing new services. Any revisit to our website will then be subject to the new data protection declaration.
