Prot-On Keep control of your files wherever they are
Prot-On is an application that ensures that the information you send by email, upload to the cloud or share on social networks can only be accessed by authorized users.
If the protected file you share is uploaded to the cloud, forwarded via mail, or passed on a "pen drive" to another person not previously authorized by you, the information will be unreadable. You maintain control over who can access your file, or any copy of that file.
Once your documents, photos or emails have been protected you then assign permissions to define who can or cannot read, print, edit, copy and manage them. You can assign or remove permissions at any time and with just once click, even after you've distributed the files.
This app is free, more info and download Prot-On
