A members-only line for one-to-one conversation. Messages live encrypted on your device — never in plaintext on any server, never readable by us, never sold to anyone.
The server only ever sees ciphertext. Keys never leave your device, so even we cannot decrypt a single word — by design, not by promise.
There is no master key, no admin override, no server-side recovery key. A compromised device can be revoked; the conversation cannot be reopened by anyone else.
No advertisers. No analytics broker. We store the minimum metadata required to deliver a sealed message and nothing about what it contains.
Privacy is not a feature you switch on. It is the entire premise.
SECRET is closed. A member you trust submits your name with a relationship and a confidence note — family, business, or friend.
Instead of an account you start with a simple group code, e.g. ALPHA. The code grants you a temporary window to be approved.
Each terminal is verified and named internally. A device that is lost or compromised is revoked — your conversations stay sealed.
One-to-one encrypted text and voice. Auto-lock after inactivity, read-once and burn options, and a key-change warning if anything about a contact changes.
SLN SECRET will offer private iPhone terminals prepared for one purpose: secure access to SECRET. Each terminal is configured manually, approved internally, and connected to the service as a controlled device.
The terminal is intended to operate with SECRET as the primary accessible application, with access to unrelated apps, settings and consumer features restricted as much as the managed device profile allows.
The terminal is designed to stay connected through mobile data or Wi-Fi while keeping the user experience focused on encrypted text and voice communication inside SECRET.
If a terminal is lost, modified, jailbroken, physically compromised or removed from its managed state, access can be revoked from the SECRET system. Privacy is strengthened by device control, not by trust alone.
Every message is sealed with modern end-to-end encryption with forward secrecy and post-compromise security — fresh keys per conversation, ratcheted per message. Voice notes are encrypted locally with a one-time key before they ever touch the network.
Your private keys are held in a hardened local vault, protected by your passphrase and biometrics, with no cloud backup and no server recovery. What stays on the device, stays on the device.
Enter your access group code to begin. Approval is granted within your access window — no public sign-up, no waiting list.
No code? Ask the member who told you about SECRET to recommend you.
