§ 3 General legal bases

For processing of personal data necessary for the performance of a contract to which the data subject is a party, Article 6 (1) (b) of the GDPR serves as the legal basis. This also applies to processing operations required to carry out pre-contractual measures.
If processing is necessary to safeguard the legitimate interests of our company or a third party and if the interests, fundamental rights and freedoms of the data subject do not prevail over the former interest, Article 6 (1) (f) of the GDPR serves as the legal basis for said processing. This is particularly the case if we use tracking to optimize the website or to measure the reach of our newsletter, as well as for direct marketing.
If the processing of personal data is required to fulfill a legal obligation to which our company is subject, Article 6 (1) (c) of the GDPR serves as the legal basis.
In the event that vital interests of the data subject or another natural person require the processing of personal data, Article 6 (1) (d) of the GDPR serves as the legal basis.

Insofar as we obtain the consent of the data subject for the processing of personal data, Article 6 (1) (a) of the EU General Data Protection Regulation (GDPR) serves as the legal basis.
