In particular, they can object to the processing of data for the purpose of direct advertising.

The data collected in this way is temporarily stored but not together with other data related to you.

This storage takes place on the legal basis of Art. 6(1)(f) GDPR. Our legitimate interest lies in the improvement, stability, functionality and security of our website.

Online job applications / publication of vacancies

Job applications

We give you the option of applying to us via our website. For these digital applications, your applicant and application data will be collected and processed electronically by us for the purpose of handling the application process.

The legal basis for this processing is Section 26(1) sentence 1 of the German Federal Data Protection Act (BDSG) in conjunction with Art. 88(1) GDPR.

If an employment contract is concluded after the application process, we will store the data you submitted during the application in your personnel file for the purpose of the usual organisational and administrative process; this is, of course, done in compliance with the more extensive legal obligations.

The legal basis for this processing is also Section 26(1) sentence 1 of the BDSG in conjunction with Art. 88(1) GDPR.

In the event that an application is rejected, we will automatically erase the data submitted to us two months after notification of the rejection. However, the data will not be erased if it is required to be stored for a longer period of up to four months or until the conclusion of legal proceedings due to legal provisions, e.g. due to the obligation to provide evidence according to the German General Equal Treatment Act (AGG).

The legal basis in this case is Art. 6(1)(F) GDPR and Section 24(1) no. 2 BDSG. Our legitimate interest lies in legal defence or enforcement of rights.

If you expressly consent to your data being stored for a longer period of time, e.g. for the purpose of your inclusion in a database of applicants or interested parties, the data will be processed on the basis of your consent. The legal basis is then Art. 6(1)(a) GDPR. However, you can of course withdraw your consent at any time in accordance with Art. 7(3) GDPR by making a declaration to us with effect for the future.

Contact requests/contact options

If you contact us via the contact form or email, the data you provide will be used to process your request. You must provide this data so that we can process and answer your enquiry – without it, we will not be able answer your enquiry at all or only to a limited extent.

The legal basis for processing data transmitted in the course of sending an email is Art. 6(1)(f) GDPR. If the email contact is intended for the conclusion of a contract or takes place within the framework of an existing contractual relationship, the additional legal basis for the processing is Art. 6(1)(b) GDPR.

Your data will be erased as soon as your enquiry has been conclusively answered and there are no legal obligations to retain the data, e.g. in the case of subsequent contract processing.

IV. Data protection information in accordance with the EU General Data Protection Regulation

The data protection information pursuant to the EU General Data Protection Regulation for authorised representatives/agents of "legal entities" pursuant to Art. 12 ff.
