It will crash. you will loose access to your files. It's a very good app when it works. However, it crashed a couple of weeks later when it was installed the 1st time. I could not do anything but uninstall it. Of cause, I lost all the decuments that I saved in it. After re-installation, it worked about 2 months until today. Please fit it, then I will give it 5 stars.

It took me a little bit to figure my way around the app, but very easy to use once you get the hang of it. Plus it hides any apps you want your devices entirely! Nobody is going to find out you have that app or how to access it! Keeps those nosy people out of your business, just don't use this app to cheat on your significant other/wife/husband. Please! I'm using this app to hide my diary from my nosy and obnoxious younger sister, the app I use to buy my phone's minutes so nobody but I can purchase service for my phone, and my feminine health tracking app. Apps that I don't need people sticking their huge nose into and/or apps that are too embarrassing to have on my phone's home screen.

Recently, I have lost all the pictures and videos I sent to Calculator. It started off by me not being able to see my pictures and then needed to click a blank video screen twice to see one video. As of a week ago, I don't have any of the cherished, very personal videos I tried to hide. Works well for me. Love that I can organize the items in different folders.
