itizu-Notes, Privacy, and SMS are dedicated private messaging applications that allow you to send and receive private text messages either by SMS, or your favorite messaging and mail applications. Using one to one privacy rather than a global password approach, itizu privacy applications keep your messages private and confidential.
For Private SMS/texting: use the dedicated itizu-SMS private text application which replaces the standard SMS application on your phone. itizu-Notes interfaces into your own SMS/MMS application allowing you to send and receive private messages with your contacts.

For multiple messaging / text processing options: use itizu-Notes. This application allows you to share private messages using your installed or favorite messaging / text processing applications.
