Actually works. I've been searching many hours for a file encryption system for Android. Most of them only password protect files in the app. The files are actually still wide open on the mobile device. Secrecy creates a vault into which you can import (move) them from the device. Even better you can export (copy) the files from Dropbox into a vault directly. This seems to be the easiest way to transfer files from computer to a secure location on a mobile device that I have found yet. If Dropbox was encrypted it would be perfect. For sensitive files it's probably better to USB them onto the mobile device instead.
