We all have private collections of photos and videos on our phones that we wish to keep away from prying eyes or annoying friends who have the habit of digging through your personal stuff. We can't do this directly with our phones, thankfully we have plenty of apps to do just this job. Here's a look at some of the popular ones on different platforms that will keep your private videos and photos, well, private.

Video Safe - iOS
This app is the number one Video Utility application, currently on iTunes worldwide for two straight years. This is a major indication to just how powerful this application is. Video Safe allows its users to protect their videos and photos from prying eyes and it does so, in a very smooth fashion. No need to worry about people accidentally stumbling into your 'special' movies or photos, any more.

Here are a few of the features of this application:

The Secret Folder - iOS
The Secret Folder offers you new ways to protect your privacy on the iPhone, iPod touch and iPad. You can set up a secret pattern code or use a pin code to unlock your phone and can Hide your private information keeping everything else untouched. You can securely store your photos and videos in a secret location right in the app. Users can create a new album, import their content and prevent access to the app with a pattern lock or secret pin code. A hidden album is the right place to put your photos and videos in, especially if you had a great party with your friends and got some spicy content to hide from others.

Spy Calc Free - iOS
Hide your private pictures and videos behind a working calculator. Type the secret number combination into the calculator to reveal your private pictures and videos. Now nobody will ever know what’s hiding behind those complex calculations and math problems you and your friends keep solving everyday. The calculator is pretty functional as well. The application has a pretty neat interface and the best part is that it is free. Also, it’s got support for a wide variety of languages as well.

Hide Pictures with Keep Safe - Android
With this application, privacy protection is made easy as pictures simply vanish from your photo gallery, and remain locked behind an easy-to-use PIN pad. This application allows you to choose and show only what you want others to see, while hiding the other pictures and videos. This puts you in control of who sees what and your public gallery remains available to your friends, family, and co-workers.

Keep Safe has the following privacy features:
