Will Marginnote last long?

Hey Everyone, I have purchased Marginnote 3 full version. So I Absolutely love the app. But many of the apps that I have used before have been abandoned all of a sudden. Which resulted In loss of all the work that I did. Can I assure myself that Marginnote is going to last for a longer period of time? How can I make sure that it is going to be there?


We want to share our Product Philosophy of MarginNote with you. Hope the statement could give you faith.
