Works exactly as described. – Folder Lock Review

Pay for the ad free version. After the 3.99 it’s a perfect app to keep people away from private videos and photos. It’s easy to use and will even scrub your phone of the videos you store in the app. The only thing is that if you delete the app without putting the videos back on your phone then you’ll lose your stuff forever.
