Using SecureMessages, you can communicate instantly while avoiding SMS fees (Free SMS-MMS on Internet connection - WIFI or 3G), create groups so that you can chat in real time with all your friends at once, and share media or attachments all with complete privacy. The server never has access to any of your communication and never stores any of your data.
★ Easy. SecureMessages works like any other SMS/MMS application. There is nothing to sign up for and no new service your friends need to join.
★ Private. SecureMessages uses an advanced end to end encryption TextSecure protocol that provides privacy for every message every time.
★ Free SMS-MMS on Internet connection (WIFI or 3G). This will help you save money!
★ Group Chat. SecureMessages allows you to create encrypted groups so you can have private conversations with all your friends at once. Not only are the messages encrypted, but the SecureMessages server never has access to any group metadata such as the membership list, group title, or group icon.
