Hello friends, this is a very useful app for hide your personal photos, videos, browser and app. It keeps hide from your best friends and your family too. The best thing is, any one cannot see it on your display. The secreat password to hide this app from display is * ##12345##* . No one can find this aap on your display. When anyone will type this password on your calling pad, your app will open. I am using this app last 2 years. It is very helpful it hide my secret. But one problem, when your mobile will lost or any other software problem, your all mobile data which are store in this app was lost. So please before going to service centre keep out your secret from this app. You will find this aap from play store. Thank you.
