7. Data collection on this website

Server LogFiles
To maintain secure server operation, information is automatically collected and stored in so-called LogFiles. Your browser transmits this information automatically. These are:
– Date and time at the time of access
– IP address used
– Browser used
– Operating system used
– Amount of data sent in bytes

This data is not merged with other data sources. The collected data will not be used for the purpose of drawing conclusions about your person. The website operator has a legitimate interest in the technically error-free presentation and optimization of its website – for this purpose, the server log files must be recorded.

Request by form, e-mail, telephone, fax or letter

If you send us enquiries via the contact form, your details from the enquiry form, including the contact details you provide there, will be stored by us for the purpose of processing the enquiry and in the event of follow-up enquiries.
If you contact us by e-mail, telephone or fax, your enquiry including all personal data resulting from it (name, enquiry) will be stored and processed by us for the purpose of processing your request.
We do not pass on this data without your consent.

The processing of this data is based on Art. 6 (1) lit. b DSGVO if your request is related to the performance of a contract or is necessary for the implementation of pre-contractual measures. In all other cases, the processing is based on our legitimate interest in the effective processing of the requests addressed to us (Art. 6 (1) (f) DSGVO) or on your consent (Art. 6 (1) (a) DSGVO) if this has been requested.
The data you send to us via contact requests will remain with us until you request us to delete it, revoke your consent to store it or the purpose for storing the data no longer applies (e.g. after processing your request has been completed). Mandatory statutory provisions – in particular statutory retention periods – remain unaffected.

Job Application

We collect and process the personal data of applicants for the purpose of handling the application process. The processing may also take place electronically. This is particularly the case if an applicant submits corresponding application documents to us electronically.
The data processing helps to carry out the application procedure, in particular to establish an employment relationship. The legal basis for this is Article 6(1) b) of the DSGVO in conjunction with Section 26 (1) sentence 1 of the German Federal Data Protection Act (BDSG) or the corresponding national law. If the controller concludes an employment contract with an applicant, the transmitted data will be stored for the purpose of processing the employment relationship in compliance with the statutory provisions.
If the applicant concerned gives his/her consent to this, the data will be stored in the event of non-employment for the consideration of the applicant for future job offers for a period of 12 months (or until any prior revocation of consent) after the conclusion of the application process.

If the controller does not conclude an employment contract with the applicant, the application documents will be deleted two months after notification of the rejection decision, provided that no other legitimate interests of the controller prevent deletion. Other legitimate interest in this sense is, for example, a duty to provide evidence in proceedings under the General Equal Treatment Act (AGG).
