An android solution in which the user's facebook data would be stored

I'm an undergraduate student, and the project what i'm doing is a mobile application where the users are able to login to facebook via the app, not the users to browse facebook, but the user's facebook data should be saved such as the current user's Statuses, to analyse later via the app.

What i need to know is, does facebook really allow users to save their profile details?

up to now what have been achieved is, user is able to login and logout via the application. i didn't step into the main purpose of the application yet which is data mining.

Tools been used : Java, Firebase IDE: Android Studio
