Yeah one way of disguising an illegal app lol. If you don't have the correct 6 digit code you cannot see the content. Content scraped from web similar to apps like cinema hd, cyberflix etc.Saw this on Google Playstore - https://play.google.com/store/apps/details?id=com.strix.strix_example&hl=en
Must be legal then
my family cinema has a similar trick as you will find their app on playstore too but it has no content. After downloading it you need to add a "content zip file" which enables all the content. Theirs is a paid service of about R60 p/m although you get premium servers and little to no buffering unlike strix / cinemahd / cyberflix etc.
