In accordance with the legal requirements of data protection law (in particular in accordance with BDSG n.F. and the European Data Protection Regulation 'DS-GVO'), we inform you below about the nature, scope and purpose of the processing of personal data by our company. This privacy policy also applies to our websites and social media profiles. Regarding the definition of terms such as "personal data" or "processing", we refer to Art. 4 DS-GVO.

2. General information on data processing

2.1 Scope of the processing of personal data

We only collect personal data which is required for contacting you by e-mail or telephone or for postal correspondence. Such data includes: Title, surname, first name, business address, business e-mail address and business telephone number.

2.2 Legal basis for the processing of personal data

If a processing of personal data is based on the consent of the data subject, Article 6 (1) (a) of the EU General Data Protection Regulation (GDPR) serves as the legal basis. If personal data is processed in order to fulfill a contract with the data subject, Art. 6 (1) (b) DSGVO serves as the legal basis. This also applies to processing operations that are necessary to carry out pre-contractual measures. If we process personal data in order to fulfill a legal obligation, Art. 6 (1) c DSGVO serves as the legal basis. If vital interests of the data subject or another natural person make processing of personal data necessary, Art. 6 (1) (d) DSGVO serves as the legal basis. If we process data to protect the legitimate interests of our company or a third party and the interests, fundamental rights and freedoms of the data subject are not more important, Art. 6 (1) lit. f DSGVO serves as the legal basis for the processing.

2.3 Cooperation with processors and third parties

If, in the course of our processing, we disclose data to other persons and companies (processors or third parties), transmit it to them or grant them access to the data, this will only be done on the basis of a legal permission (e.g. a transfer to payment service providers required for the performance of a contract pursuant to Art. 6 (1) lit. b DSGVO), consent, a legal obligation or on the basis of our legitimate interests (e.g. when using agents, web hosts). If we commission third parties with the processing of data on the basis of a so-called "order processing agreement", this is done on the basis of Art. 28 DSGVO.

2.4 Transfers to third countries

If we process data in a third country (i.e. outside the European Union or the European Economic Area) or do so in the context of using third-party services, this will only be done if it is done to fulfill our (pre)contractual obligations, on the basis of consent, due to a legal obligation or on the basis of our legitimate interests. We process data subject to legal or contractual permissions only if the requirements of Art. 44 et seq. DSGVO are present: Data is thus only processed if, for example, special guarantees exist, such as official recognition of a level of data protection that corresponds to the EU (e.g. "Privacy Shield") or compliance with officially recognized contractual obligations (so-called standard contractual clauses).

2.5 Data deletion and storage duration

As soon as the purpose of the storage ceases to apply, personal data of a data subject will be deleted or its processing restricted ("blocked"). If European or national regulations, laws or other provisions to which we are subject require longer storage, the personal data will be stored in accordance with these legal provisions for longer than the original purpose intended.

2.6 Data deletion upon revocation

All data collected until revocation will be deleted immediately - unless a legal requirement requires retention.
