S2S is the ideal app for the storing and sharing of sensitive information and can handle all types of media files, notes, voice messages, photos, videos, documents, etc.
Through the magic of public key encryption there is no sharing of passwords that have to be kept secret, everyone has their own encryption key associated with their email address. Sensitive information can be shared without any fear of interception or access by anyone other than the intended people you want to share the information with. More Info »
You can therefore share intimate messages or photos with your friends; or sensitive work information with your colleagues without any fear of being eavesdropped.
