Use of this website

Thank you for your interest in this website. We take the protection of your privacy in the collection, processing and use of personal data very seriously. In the following, we will inform you which data may be collected via our website and for what purpose.

When you visit this website, information about the access is recorded in a so-called log file. This information includes your IP address, the date and the pages you have accessed. This data is automatically analysed for statistical purposes and is used to optimise and design our applications to meet your needs. They cannot be assigned to a specific person.

If you send us personal data as part of an enquiry, we will only use, store and treat it confidentially for the purposes communicated.


We use so-called “cookies” on our website, which enable an internet browser to be recognised. Cookies are small text files that are sent from the web server to your web browser and stored on your hard drive. They provide information about the use of our website and are used for statistical purposes. You can specify in your browser settings whether you allow or exclude the use of cookies or whether the use of cookies requires your confirmation.


This website uses the open source web analysis service Matomo.

With the help of Matomo, we are able to collect and analyse data about the use of our website by website visitors. This enables us to find out, among other things, when which pages were accessed and from which region. We also record various log files (e.g. IP address, referrer, browser and operating system used) and can measure whether our website visitors perform certain actions (e.g. clicks, purchases, etc.).

The use of this analysis tool is based on Art. 6 para. 1 lit. f GDPR. The website operator has a legitimate interest in analysing user behaviour in order to optimise both its website and its advertising. If a corresponding consent has been requested, the processing is carried out exclusively on the basis of Art. 6 para. 1 lit. a GDPR and § 25 para. 1 TTDSG, insofar as the consent includes the storage of cookies or access to information in the user’s terminal device (e.g. device fingerprinting) within the meaning of the TTDSG. Consent can be revoked at any time.

Spam protection for contact form

We use “Google reCAPTCHA” (hereinafter referred to as “reCAPTCHA”) on this website. The provider is Google Ireland Limited (“Google”), Gordon House, Barrow Street, Dublin 4, Ireland.

The purpose of reCAPTCHA is to determine whether data entered on this website (e.g., information entered into a contact form) is being provided by a human user or by an automated program. To determine this, reCAPTCHA analyzes the behavior of the website visitors based on a variety of parameters. This analysis is triggered automatically as soon as the website visitor enters the site. For this analysis, reCAPTCHA evaluates a variety of data (e.g., IP address, time the website visitor spent on the site or cursor movements initiated by the user). The data tracked during such analyses are forwarded to Google.

Data are stored and analyzed on the basis of Art. 6(1)(f) GDPR. The website operator has a legitimate interest in the protection of the operator’s websites against abusive automated spying and against SPAM. If a respective declaration of consent has been obtained, the data will be processed exclusively on the basis of Art. 6(1)(a) GDPR. Any such consent may be revoked at any time.
