Without further ado, I bring you the top 5 privacy applications for the Android OS (in no particular order).
droidHunter: A complete security service for Android with integrated anti-virus, intrusion detection, online managing service and incoming alerts. This app is similar to your traditional desktop security software except that it looks for Android specific threats. My Android phone scans as "Very Clean" but user reviews report the interception of suspicious apps as well as other Android security threats. This program comes in a free version as well as a paid version which can be used to locate or wipe a lost or stolen phone.
App Protector: An application which allows you to lock your choice of applications on your Android phone. Set a password code or pattern and be prompted for it when trying to access protected applications. Useful if your phone is stolen or if you store information on your phone you'd rather not have accessed by people you let look at your Android phone. Protect as many or as few applications as you like and remove the password lock on applications at anytime. One thing to keep in mind is you will want to protect your uninstaller application(s) so a person can't simply uninstall this program to remove the password locks and then access your sensitive information. This program comes in a free time-limited trial (7 days) and will cost you $1.99 if you decide to continue to use it.
PhotoVault: This Android application lets you password protect single photos or a directory of photos on your Android phone.
VideoVault: Much like PhotoVault, VideoVault for Android lets you password protect any video footage you have on your phone.
aFirewall / Android Firewall: aFirewall is the free version of Android Firewall which blocks incoming calls from numbers you specify. This application works fantastically and is a must-have for anyone who wants to block incoming calls from telemarketers, bill collectors or your run of the mill harassing calls. aFirewall is free to download and try and if you like the application it will only cost you $1.99 to upgrade to the fully functional Android Firewall.
