We have made an app, in which we wish to store contact information of external people. This includes name, phone number, email adress, role and some internal comments. Like a digital address-book.
I am new to GDPR and need some help setting this up. Would very much appreciate if someone could explain all the neccesary steps.
For example, do we have to inform the contacts that their information is stored in appfarm, and if so whats the best way to do this?
