What action should an APP entity take if it possesses outdated personal information?

The appropriate action for an APP entity when it possesses outdated personal information is to correct it to ensure it is up to date. This aligns with principles of data accuracy and the obligation to maintain personal information that is relevant and current. By correcting outdated information, the entity ensures that the data it holds reflects the true situation of the individual, which is crucial for maintaining trust and compliance with data protection laws.

Accurate and current personal information is essential for a range of purposes, including effective communication, relevant service delivery, and decision-making processes that rely on personal data. Maintaining outdated information could lead to misunderstandings or mistakes that adversely affect individuals.

In terms of other options, storing outdated information for historical purposes might seem appealing, but it doesn't address the core responsibility of keeping personal data accurate. Automatically deleting the data without user consent may violate privacy regulations, which require entities to handle personal information with care and respect for individual rights. Keeping the information as it is may lead to confusion and hinder the entity's ability to serve individuals effectively. Therefore, correcting the information to ensure accuracy and relevance is the best practice.
