General information

There are many ways to exchange information with us. Personal data, for example, may be transferred by e-mail, using a contact form on the website, by post, by telephone or at a personal meeting.

If you provide us with personal data such as e-mail addresses, names, addresses, application documents or information for interested parties, etc., you are solely disclosing this data voluntarily. The use of a communication channel with us represents the implied consent for the transmitted personal data to be processed. The purpose of the processing is based on the person's request, e.g. responding to a request from an interested party or reviewing an application.

This personal data will not be passed on to third parties except for companies or service providers affiliated with us. We only pass on personal data to third parties who are obligated to handle this data in a confidential and lawful manner.

We will inform the people concerned of any changes for the purpose of data processing.

We would like to point out that there may be security risks with the data transfer on the Internet (e.g. when communicating via e-mail). Complete protection of data against access of third parties is not possible.

Online forms on our website

If you send us requests by online form, your information from the request form including the contact details you have specified therein will be processed by us for the purpose of processing the request.

The processing of the data entered in the contact form is carried out solely based on your consent (in the EU based on Art. 6(1a) of the GDPR). You can revoke this consent at any time. An informal communication to us by e-mail is sufficient here. The legality of the data processing procedures carried out until the revocation remains unaffected by the revocation.

The data you have entered in the contact form is stored by us until you ask us to delete it, your consent to store it is revoked or the purpose for data storage ceases to apply. The right to store data for longer due to special legal stipulations or due to impending legal disputes or legal disputes that have not been concluded is reserved.

Our website sometimes uses cookies. Cookies are used to make our website more user-friendly and to improve efficiency and security. Cookies are identifiers which a web server can send to your computer to identify it for the duration of the visit.

IP anonymisation

We have activated the IP anonymisation function on this website.
