I need an hideapp

I need an Android app. I would like it designed and built. It has to be on Android phones or tabs or basically the Android OS So what the app does is it hides your selected phone apps that you don't want users to see Um this is different it conceals those selected apps from the main launcher And those apps could be accessed by either another app like a calculator So the calculator would be like the gateway to the other partition of your Android phone Okay the basic functionality is that it partitions your Android phone , into two halves , one half serves as the outside view of your phone or public view , that is apps you want people to see , while the other half serves as your storage lock for apps you don't want people to see and to get to this storage lock you'd need to type in a certain pass code in your calculator that launches you to that second part Do you get the broad picture now ?
