This is a nice little app and I can appreciate that in a world of data mining this app doesn't seem to data mine anything. It only requests the most obvious permissions  being able to read/write to photos and videos which such an app would need. I also appreciate the color chart that allows you to make the various aspects of the app literally any color that you want  no having to choose from a few colored templates. Knocking it to one star however stems from the glaring security omission of not having a lock or pin method between prying eyes and hidden folders/photos. Whether someone is just fooling with your device let alone someone intent on finding any dirt you may have in your gallery; if they see a ""show hidden folder/photo"" button they're going to press it. And where's the second place they'll look when nothing happens? The Settings where they'll find a simple on/off toggle and poof  you're hidden folders/photos appear and you'll be embarrassed if not worse. A third party app or some virus protection apps can lock apps but they'll lock the whole app  not specific folders...
