# Consent (legal basis)

Under the [GDPR](/dictionary/gdpr.md), [PII](/dictionary/pii.md) can only be collected and/or processed under a ‘legal basis’ (or simply, only if there is a reasoning for the processing). 

A [Processor](/dictionary/data-processor.md) or [Controller](/dictionary/data-controller.md) can rely on gaining the customer’s consent as a reasoning for data processing. 

For consent to be compliant, it must be:

* Freely given by the individual;
* Specific of what PII will be processed, how and why; 
* Communicated to the individual so they understand what, how and why PII will be processed (informed); and,
* A clear approval (an unambiguous indication of an individual's agreement) to the processing of their PII.
