If you have ever sent a text message and wanted to know for certain that only the recipient would see it and no “paper trial” would be left, StealthText service may be for you.
Designed for sensitive business information and celebrity love affairs StealthText is about to offer a service that automatically deletes received text messages after about 40 seconds.
All the messages will be logged on a private server that only the sender has access to. To reply the recipient must also have a StealthText Account as well. Source
