How can i hide my online banking app?

I just wanted to know i about app lock i tried LEOMaster for the same and i’m happy but i wanted to know there is version update in the same app should i go with the new version ? or will it harm my old data ? do any one know such kind of situation happen to any one or should i try to recover the data and then try to re lock the same things

You could use Leo Privacy Guard to place a lock on it.
