The Privacy Centre App has a two-fold purpose.
The first is as the place to set up Consents and Topics. These are used primarily on forms to explain to a student why you are collecting their data, and what you would like to contact them about in future.
The second is to set up the Student Privacy Centre portal. This is where the student can manage their consents, topics and personal data. It also allows you to add categories and other details to the "Contact Us" page.
Under Settings, you can style the portal to better reflect your establishment's needs, and also preview how the portal will look for a student.
