01 Quick Start Tutorial

1. Install

Grab the app for your device. If on Android, you can even use the direct APK.

  • Grant Permissions
  • Finish Setup Wizard
  • Set Biometric Lock

2. Link Keys

The secret sauce. You and your contact need a shared "Key" to unlock messages.

Pro Tip: Use a shared "Passphrase" that only you two know for instant setup!

3. Go Secure

Just type and send. The app handles the heavy military-grade encryption in real-time.

"Hello" "A8x!9z..."

02 Common Questions

How secure is Secure SMS?

We use AES-256 encryption. It would take a supercomputer billions of years to crack your message. Your privacy isn't just a promise; it's math.

Does it work without internet?

Absolutely. It uses your cellular SMS network. No Wi-Fi or data required. If you can send a standard text, you can send an encrypted one.

Can I message between Android and iOS?

Yes! Our protocol is cross-platform. As long as both parties have the app and the shared key, the OS doesn't matter.

Backup Your Keys

While we offer export/import functions, remember: exported key files are not encrypted themselves. Keep your backups in a safe, offline place!
