Keep Your Data Safe With Loky
If you have a habit of keeping delicate personal information on your phone, it might be in your best interest to invest in the Loky app for Android. The app essentially creates a password-protected safe zone on your handset where you can store files, contacts, and even private SMS text messages that you don't want anyone else to read. You can hide photos, too, so people can't find your embarrassing snapshots by digging through your gallery.
Text-message conversations won't show up in your normal messaging inbox--instead, you can set a custom notification to pop up whenever the other person responds. But I can think of only two reasons why someone would have a need for this feature: Either they're a superspy or they're having an affair and trying to cover their tracks. Another feature that I think wouldn't be practical for anyone other than a secret agent is the ability to create a separate password that leads to a dummy account; why the average person would need that is beyond me. Regardless, Loky does what it claims (even though it seems to take things to the extreme). You can pick it up in the Android Market for about $4.63 and keep all of your secrets safe.
