Purposes and legal basis of data processing

We process your personal data in compliance with the provisions of the German Data Protection Regulation (DSGVO), the German Federal Data Protection Act (BDSG-neu) and all other applicable laws only to the extent necessary to provide the information on this website and our services on this website.

In the case of merely informational use of the website, i.e. if you do not log in to use the website, register or otherwise transmit information to us, we do not collect any personal data, with the exception of the data that your browser transmits to enable you to visit the website. These are:

In order to secure the proper functioning of the website, data is stored in log files. This data is also used to ensure the security of our information technology systems and to optimise the website. These data will not be combined with data from other sources.

Art. 6(1)(f) DSGVO forms the legal basis for the temporary storage of data and log files.

If the processing operations of personal data are based on the consent of the concerned person, Art. 6(1)(a) DSGVO serves as the legal basis.

Article 6(1)(d) DSGVO is the legal basis in cases where vital interests of the persons affected or of another natural person require the processing of personal data.

If personal data are processed in order to protect our legitimate interests or those of a third party, the interests, rights and freedoms of the person concerned are secondary. Art. 6(1)(f) DSGVO is the legal basis for this processing.

Personal data may be shared with the IT service providers of this website.

Data security

We maintain up-to-date technical measures to ensure data security, in particular to protect your personal data from risks during data transmission and from third parties gaining unauthorised disclosure. These are constantly adapted to the current state of the art.

You have the rights to

Please send any requests for information or objections to data processing by e-mail to the address listed above.

Right to object to the processing of personal data

You have the right to object to the processing of your personal data for direct marketing purposes without giving reasons. If we process your data to protect legitimate interests, you may object to this processing on grounds relating to your particular situation. We will then no longer process your personal data unless we can demonstrate compelling legitimate grounds for the processing which override your interests, rights and freedoms, or the processing serves to assert, exercise or defend legal claims.

In order to provide the website and to ensure the operation of the website, the collection of data and their storage in log files are mandatory. Therefore, there is no possibility for the user to object.

If log files are stored, they are deleted after eight weeks at the latest. No further processing takes place.
