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.
Encrypted content is stored only until delivery or read, then removed. SECRET does not retain encrypted message data on its servers longer than necessary.
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.
Access is activated through approved onboarding, Apple App Store subscription, and device authorization.
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 configured for mobile data through a SIM card only. Wi-Fi access is disabled in the managed profile to reduce exposure outside the approved network path, keeping the 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.
SECRET includes a Panic Code flow for situations where access must be destroyed fast. Once executed, the account is disabled and anonymized, active sessions are removed, approved device records are revoked, and linked encrypted data records are purged from the server.
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. Inside the app, screenshot and screen recording protection helps reduce unauthorized capture on supported iOS devices.
