In the case of personal data processing that is necessary for the performance of a contract to which the data subject is party, the lawful basis is Article 6 (1) b) GDPR. The same applies in the case of processing operations required to perform pre-contractual tasks.

Where personal data processing is necessary in order to protect the vital interests of the data subject or of another natural person, the lawful basis is Article 6 (1) d) GDPR.
