Processed Data

We place great importance on the protection of your personal data. In using our website and services, we primarily process the data necessary for use, which you transmit to us, as well as the information we collect directly (see below).

In the course of using our website and services, we collect metadata, such as information about your browser (type and version), your device type (e.g., smartphone or tablet), and your IP address. Furthermore, we collect access data, also known as log data. This includes the name of the accessed website, date and time of access, the amount of data transferred, notification of successful retrieval, information about the operating system, and details of the last visited website.

We only store and process further data about you if you transmit this data to us in the course of using services and tools (e.g., contact form). Further data protection-relevant information for specific tools can be found further down in this privacy statement if applicable.


We process your data exclusively for the purposes we have informed you about at the time of collecting your data and for other purposes compatible with these objectives. Further information on the basis of our data processing can be found further down in this privacy statement.

Processing of Data

We process your data for various purposes related to communication with you. This includes, in particular, responding to inquiries, asserting your rights, and contacting you if there are any questions. In doing so, we mainly use communication data and master data, as well as registration data regarding offers and services you have used. This data can be stored for documentation purposes, training, quality assurance, and inquiries.

Furthermore, we process data for marketing purposes and customer relationship maintenance. We can send general or personalized information about our offer to our users, for example, in the form of irregular contacts by email, post, or telephone, and through other channels for which we have contact information from you. You always have the option to reject such contacts or to refuse or revoke your consent to contact for advertising purposes. With your consent, we can tailor our online offer more specifically to the needs of our users.

Moreover, we can use your data for market research, to improve our online offer, our services, and possibly for product development.

Finally, we may also store and process your data for security reasons and for access control on our website.


We mainly use data for creating server log files to carry out statistical evaluations for the operation of the website, ensure the security of IT systems, and optimize the website. Here, we primarily use log data. The legal basis for this data processing is our legitimate interest in offering you a secure and smooth user experience at all times. We also reserve the right to subsequently review the log data if there are concrete indications of illegal use.

Google Fonts

We may use Google Fonts on our website to display selected fonts as well as icons and symbols on our website. This is a service provided by Google LLC (1600 Amphitheatre Parkway, Mountain View, CA 94043, USA).

Further information on Google Fonts can be found at the following link:

Adobe TypeKit Fonts

For the uniform display of fonts, we use so-called Web Fonts provided by Adobe. When you call up a page, your browser loads the required Web Fonts into your browser cache to display texts and fonts correctly. For this purpose, the browser you are using must connect to Adobe's servers. This allows Adobe to know that our website was accessed via your IP address. The use of Adobe TypeKit Fonts is in the interest of a uniform and attractive presentation of our online offers. The legal basis is Art. 6 Para. 1 lit. f GDPR.

Further information on Adobe TypeKit Fonts can be found in Adobe's privacy policy:

You can set your browser so that the fonts are not loaded from Adobe servers (e.g., by installing add-ons like NoScript or Ghostery). If your browser does not support Adobe Fonts or you block access to Adobe servers, the text will be displayed in the system's standard font.


We host our website with Webflow. The provider is Webflow, Inc., 398 11th Street, 2nd Floor, San Francisco, CA 94103, USA (hereinafter: Webflow). When you visit our website, Webflow collects various log files including your IP addresses.

Webflow is a tool for creating and hosting websites. Webflow stores cookies or other recognition technologies that are necessary for the presentation of the page, the provision of certain website functions, and ensuring security (necessary cookies).

Details can be found in Webflow's privacy policy: EU & Swiss Privacy Policy | Webflow.

The use of Webflow is based on Art. 6 Para. 1 lit. f GDPR. We have a legitimate interest in the most reliable presentation of our website possible. If a corresponding consent was 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 end device (e.g., device fingerprinting) within the meaning of the TTDSG. The consent can be revoked at any time.

Data transfer to the USA is based on the standard contractual clauses of the EU Commission. Details can be found here: EU & Swiss Privacy Policy | Webflow.

Order Processing

We have concluded a contract for order processing (AVV) with the above-mentioned provider. This is a data protection contract required by law, which ensures that the provider processes the personal data of our website visitors only in accordance with our instructions and in compliance with the GDPR.

Social Media Plugins

We may integrate services from various social media on our website, which are usually recognizable by the respective company or network logos.

When using these services, it results in their providers being communicated your IP address. The providers can possibly link your data with your social media user account if you are logged in at that time. In addition, it is possible that your IP address is stored by the providers even in logged-out state or without a corresponding social media account.

The legal basis for processing your data is based on our legitimate interest in providing attractive tools related to social media on our website.

Due to the technical structure of the Internet as an open network, secure transmission of your data cannot be guaranteed in all cases. If you send your personal data to us, then this always happens at your own risk.

To ensure the protection of your transmitted data, we use encryption mechanisms according to current security standards (Transport Layer Security, TLS). TLS is a protocol for secure data transmission on the Internet and is supported by most browsers. It uses the public-key procedure, where data is encrypted with a publicly accessible key and can only be decrypted with a specific private key. Most browsers indicate whether a connection is secure by displaying a key symbol or padlock.

We take various technical and organizational security precautions to ensure the protection of your data within our system. However, we would like to point out that despite these measures, the risk of data loss, unauthorized access to, or manipulation of data by third parties exists. Please also note that certain network sections and your computer are outside our controllable security area. As a user, you are responsible for informing yourself about necessary security precautions and taking the necessary measures within your area of influence. Liability on our part for damages resulting from data loss or manipulation is fundamentally excluded.

Data Retention

We store your data only as long as necessary for the purposes stated by us or as we are legally or contractually obligated. Data that is no longer necessary for the stated purposes will be deleted by us as part of our regular data maintenance or alternatively anonymized.


This privacy information is not part of the contract and can be changed by us at any time. The version published here always applies.
