What information must be provided to data subjects in all circumstances?

Data subjects must be provided with information about their rights in all circumstances. This requirement stems from the principles of transparency and accountability embedded in data protection regulations, such as the General Data Protection Regulation (GDPR). By informing data subjects of their rights, controllers empower individuals to understand how their personal data is being handled and what options are available to them regarding access, rectification, erasure, objection, restriction of processing, and data portability. This helps to build trust and encourages compliance with data protection laws.

While the identity of the controller, the controller's legitimate interests, and the purpose of processing are also important pieces of information that must be communicated to data subjects, they may not be required to be provided in every situation. For instance, certain processing activities based on legal obligations might not necessitate detailing the legitimate interests of the controller. However, the rights of data subjects are a fundamental component of the GDPR and must always be clearly communicated.
