The right to be informed is the right of data subjects to be provided with clear, transparent information about how a business collects and uses personal information, as well as other details such as who the data may be shared with and how long it is stored for.
This right is granted to data subjects by the GDPR and other global privacy laws.
The easiest and most common way to meet his right is by having a publicly-displayed Privacy Policy that discloses your privacy practices, thus informing data subjects.
