II. General information on data processing
1. Scope of the processing of personal data
We process personal data of our users only to the extent necessary to provide and optimize a functional website and our content and services.
The processing of personal data of our users only takes place regularly with your consent. An exception applies in cases where the processing of data is permitted by law.
2. Legal basis for the processing of personal data
Art. 5 para. 1 GDPR contains the basic rules of data processing which must be observed when processing personal data and which characterize the GDPR. One of these principles is the "principle of lawfulness" pursuant to Art. 5 para. 1 lit. a GDPR, which is set out in Art. 6 GDPR. Art. 6 para. 1 GDPR stipulates that processing is only lawful if at least one of the conditions exhaustively listed therein is met. In addition, EC 40 states that for processing to be lawful, either consent must be given or another legal basis for the processing must exist.
Art. 5 para. 1 lit. a GDPR thus implements Art. 8 para. 2 sentence 1 CFR (European Charter of Fundamental Rights), which guarantees the data subject that their personal data may only be processed with their consent or on another legitimate basis regulated by law.
3. Data erasure and storage duration
Your personal data will be deleted or blocked as soon as the purpose of storage no longer applies.
