Built-in phone messaging is tied to your number and can quietly fall back to unencrypted SMS. Many of these apps also back conversations up to the cloud, where messages may be accessible.

Built-in phone messaging looks private on the surface. Underneath, your messages are more exposed than you think.
A chat can be encrypted in transit, but when it backs up to the cloud, those messages may be stored in a form the provider can access. theSHFT generates and stores your keys on-device only — the server can never read your messages.
When you delete a message in built-in apps, copies may still live in cloud backups and on the other person's device. theSHFT self-destruct timers run from 5 seconds to 24 hours, with a live countdown, and remove the message from both devices.
Built-in messaging ties your identity to your phone number and can quietly drop to unencrypted SMS. theSHFT needs no phone number, no email, and no personal info — just a username and PIN, secured by a 12-word recovery phrase. Screenshots and screen recording are blocked, and the other party is notified if a capture happens.
