The General Data Protection Regulation requires proof of a legal basis for the purpose of processing personal data (Section 6 of the GDPR). For this, the following means are available:
- The data protection dialog for persons (Additional data/Data protection) serves to capture purposes of use, given or refused consent, a mail or email series lock, and a validity date (retention period or expiration date). It is initially empty and can be set manually or functionally.
- The log of the purpose of use servers to document all changes and references the respective activity (e.g., telephone call, mail), IP address, etc.
- When importing persons, a purpose of use can be assigned to them.
