End-to-End Encryption Explained: Your Messages, Your Keys

Many apps claim to be "encrypted". But what does that actually mean — and when is encryption truly secure? A clear explanation without the jargon.

Not All Encryption Is the Same

The word "encrypted" appears in many app descriptions. But there is a critical difference between transport encryption and end-to-end encryption (E2EE) — and it matters enormously for your privacy.

Transport Encryption (TLS)

Transport encryption protects your messages on the way from your device to the server. That sounds good — but it only goes halfway: the server itself can read the message in plain text. The operator has access. Authorities can request it.

End-to-End Encryption (E2EE)

With true E2EE, your message is encrypted on your device before it leaves. It can only be decrypted on the recipient's device. No server, no operator, no one in between can read the content.

How Journey Implements E2EE

Journey uses end-to-end encryption for all messages. In practice, this means:

  • Messages leave your device already encrypted
  • Only the recipient holds the decryption key
  • Even if servers were compromised, messages remain unreadable
  • No Journey employee can read your messages

What Encryption Does Not Protect Against

Important to understand: even E2EE does not protect against everything. If your device is unlocked and someone has physical access, messages can be read. That is why you should always secure your device with a passcode or Face ID at the operating-system level and never leave it unlocked and unattended.

Conclusion

End-to-end encryption is the gold standard for messengers. Journey provides this security by default — for all chats, without exception.
