Storage limitation at a glance:

Storage limitation (even if not implied by its name) considers the degree to which data subjects are identified by the data, i.e., how easy data subject can be associated with the data. The degrees of identification foreseen in the GDPR are directly identifying data that contain identifiers, pseudonymous data, and anonymous data. Data shall be collected with the lowest degree of identification possible and pseudonymization and anonymization shall be used to further reduce the identification as soon as possible over time.
