TTL (Time-to-Live) is a feature that automatically deletes messages after a specified duration (such as 5 seconds, 1 minute, or 1 hour). Once the timer expires, messages are permanently erased from all devices and cannot be recovered.

At this time, OTRx supports encrypted text messaging only. File sharing capabilities are planned for future versions of the app.

Download OTRx from your app store, enter a valid licensing key to unlock the app, then tap 'Sign Up'. Enter your phone number and verify it with the OTP sent to your phone. You can enable biometric authentication (Face ID) during sign-up or later in your settings.

OTRx uses OTP (One-Time Password) for login verification instead of passwords. When logging in, enter your phone number and you'll receive an OTP via SMS. Use that OTP to access your account. If you're having trouble receiving OTP, check your phone number is correct and ensure SMS is enabled on your device.

Open the app, go to Settings > Privacy and Security > Delete My Account. Your account and all associated data will be permanently removed from our servers. This action cannot be undone.
