Absolutely idiotic. – Secret Vault - Photos & Videos Review

This is stupid. The so-called purpose is to prevent people from finding out you have stuff in your calculator, but nope, the app name is “Calculator Vault”. Defeats the whole purpose of having an app like this. Would have been a wonderful app hadn’t it been for this very dumb mistake on the developer’s part.
