What is the key principle regarding data retention according to GDPR?

The key principle regarding data retention under the General Data Protection Regulation (GDPR) is that data should not be kept longer than necessary for the purposes for which it was processed. This principle aligns with the GDPR's emphasis on data minimization and the protection of individuals’ privacy rights. Organizations are required to establish clear retention policies that define the duration for which personal data will be stored, ensuring that data is only held for as long as it is needed to fulfill the original purpose for which it was collected.

Once the purpose is fulfilled or the data is no longer necessary, organizations are obligated to securely delete or anonymize the data. This principle not only helps in complying with legal obligations but also promotes responsible data management practices, ultimately enhancing trust between organizations and individuals.
