If you are alarmed by hackers and others reading your E-Mail, then use Privacy Envelope. If you are alarmed that your photos, movies, E-Mail, contacts, business and sales plans, or any of your private files which are stored in a Cloud-based environment are exposed to your business competitors or to hackers who would steal your identity, then use Privacy Envelope.
Privacy Envelope is a simple-to-use application which does not use Servers and does not use Subscriptions. All operations of Scrambling and Revealing of data files are performed by the users themselves. This means that you do not need to trust any other entity who you do not know to secure your data while it is either traversing through the Internet or stored on a provider's E-Mail or Cloud storage Server.
