data recovery from discontinued app

Well, hello guys. I will be straight forward with this one: I need to get back data (over 3000 notes (23 mbs)) from a discontinued app (S note) on my samsung cloud. It shows it's existence there allong with the mbs, but when i try to restore it, the cloud only allows me to restore the notes from my Samsung Notes (that were synched from my other samsung device .). Can somebody help me?
