Data protection is the right of every individual to decide for themselves about the collection and use of their personal data. In Germany and the EU, this right is protected by the GDPR, the Federal Data Protection Act (BDSG), and other regulations.
Personal data in marketing
Personal data is regularly processed in marketing: name, telephone number, email address, purchase history, or location data. Any processing of this data must be based on a valid legal basis – usually the explicit consent of the data subject.

- Obtain opt-in: Marketing messages may only be sent after explicit consent.
- Data minimization: Only collect and store the data that is absolutely necessary.
