If you have a business or maybe just nosy friends Andrognito is for you. This app allows you to keep all of your personal files personal with a 3-Layer encryption engine. You can hide your personal photos, clients lists, and any other important document and rest assured that only you will ever be able to access them. The important, apps, photos, videos, and documents are stored safely in a vault that you can access with a PIN. The app is super quick and easy to use.
It should be noted that if you uninstall the app with your files inside the folder those files will also be permanently deleted from your device. This device is also in BETA so be aware that there may still be a few bugs. If you would like to give this app a try head to the play link below.
