Silence is an SMS/MMS application that allows you to protect your privacy while communicating with friends. Using Silence, you can send SMS messages and share media or attachments with complete privacy.
Since metadata is not protected Silence doesn't allow protecting privacy and doesn't enforce complete privacy. It only allows confedintiality and possibly (I have not dug into it or actually used, just saw it announce in f-droid) integrity of the messages.
