Can personal data of Facebook users be collected?

Question

Facebook

There is an application with Facebook integration. Is it possible to collect information from users who have logged in through Facebook (thus allowing access to the application of their account) and transfer it to their own server in order to obtain the target audience and further develop the application?

Answer 1

Write in the user agreement, something like:
Directly write what you will do with the data, everything that the user agreed with you can do.
Well, add a section that you take all necessary measures to protect personal data from unauthorized access, alteration, disclosure or destruction. Blah blah...
Also look here Getting data from a social network and the Federal Law "On Personal Data" are there any problems?Here in case you decide to collect data from the social network without user intervention.
