This fundamental right also includes the right to "informational self-determination". Basically, it must be the decision of each individual to disclose his personal information and how they are used.

From this point on all data processors are directly obliged to comply with the rights and obligations arising from the EU GDPR.
Special care must be taken when processing personal data for direct marketing purposes.
