Legal basis for data processing

Unless more specific legal provisions exist, the legal basis for the processing of personal data is Art. 6 GDPR. The following possibilities may apply:

  • Consent (Art. 6(1)(a) GDPR)
  • Data processing for the performance of contracts (Art. 6(1)(b) GDPR)
  • Data processing for the purposes of legitimate interests (Art. 6(1)(f) GDPR)
  • Data processing for compliance with a legal obligation (Art. 6(1)(c) GDPR)

If the processing of your personal data is based on your consent, you have the right to withdraw this at any time with future effect by notifying us accordingly.

Data storage period

We will process your data for as long as this is necessary to fulfil the purpose for which it was collected.

Where statutory retention periods apply, e.g. in commercial or tax law, the respective personal data will be stored for the duration of the statutory retention period. Once the statutory retention period expires, we will determine whether the processing is still necessary. If it is no longer necessary, the data will be erased or destroyed.

In principle, we review the data at regular intervals to determine whether further processing is necessary. Due to the sheer volume of this data, the review encompasses specific data types or the purposes for which it is processed.

You have the option to obtain information from us at any time as to which of your personal data we are storing. If the data processing is not necessary, you can ask for your data to be erased or have the processing thereof restricted.

Transferral of data

In principle, your personal data is only transferred to third parties if this is necessary for the performance of our contract with you, if the transfer is admissible for purposes of our legitimate interests within the meaning of Art. 6(1)(f) GDPR, if we are obliged by law to transfer your data, or if you have given us your consent thereto.

Data processing location

Rights of data subjects

Furthermore, you have the right to request the rectification or erasure of your data and to request restriction of the processing thereof insofar as this is admissible by law. You also have the right to object to the processing of your personal data within the scope of the law. The same applies to your right to data portability.

In particular, you have the right pursuant to Art. 21 par. 1 and 2 GDPR to object to the processing of your data for direct advertising purposes if this is carried out on the basis of a legitimate interest.
