QuantorPhone is a post-quantum encrypted communications platform for iPhone — voice, video, messaging and files, end-to-end, on infrastructure you own. No cloud. No backup. Nothing to seize.
Talk, message, meet and move files with the same guarantee: encrypted on your device, encrypted in transit, and unreadable to anyone who intercepts the line or seizes the handset.
Hybrid ML-KEM-1024 + X448 key agreement protects every message, call and file against capture-now-decrypt-later attacks.
Post-quantum encrypted calls with AES-256 media. Keys are negotiated on the endpoints — the server never sees them.
Set an ephemeral timer per conversation. Messages self-destruct on both devices once read — no residue left behind.
An AES-256-GCM virtual filesystem holds all content. The key is random, device-sealed in the Keychain, and never exported.
A 6-digit PIN on a shuffled keypad, bound to the Secure Enclave. A separate duress PIN unlocks a decoy — never the real data.
One command destroys the device remotely — even while the screen is locked. You define the secret trigger word yourself.
Blank preview in the app switcher, blocked screenshots and recording, and a low-emission mode that minimizes what the display reveals.
No iCloud, no sync, no telemetry. The app's data container is excluded from device backups — it exists in exactly one place.
Self-hosted servers, mutual-TLS client certificates and your own root of trust. No dependency on QuantorPhone-operated systems.
Per-contact key fingerprints and trust verification confirm you are talking to the right endpoint — not an impostor on the wire.
One-to-one, group chat and end-to-end encrypted conferences with encrypted file transfer — the whole team on one hardened channel.
A field-ready interface localized into 19 languages, with a dark theme set as the default for low-visibility use.
Consumer "secure" messengers defend against today's interception. QuantorPhone is engineered for a harvest-now-decrypt-later world and for devices that fall into the wrong hands.
| Control | QuantorPhone | Consumer secure messengers |
|---|---|---|
| Encryption | Post-quantum hybrid — ML-KEM-1024 + X448 | Classical elliptic-curve only |
| Infrastructure | Self-hosted, under your control | Vendor-operated cloud |
| Data at rest | Encrypted vault, keys sealed to the device | Standard app sandbox |
| Cloud backup | —None; excluded from backup | iCloud / Google on by default |
| Compromised device | Remote crypto-erase, works while locked | Limited or none |
| Coercion | Duress PIN opens a decoy | None |
| Identity | mTLS certificates + key fingerprints | Phone number |
A calm, dark, field-ready interface — the complexity is in the cryptography, not on the screen.
No "military-grade" hand-waving. Here is exactly what runs under the hood.
The real test of a secure phone is what an investigator can pull off it after seizure. QuantorPhone is assessed against GrayKey — the forensic platform used to extract data from locked iPhones.
The full report — methodology, device state and exactly what could and could not be recovered under forensic extraction — is prepared by Luca Cadonici (Secure Path) and will be published here on completion.
Report · coming soonQuantorPhone runs on infrastructure you operate — on-premises or in a sovereign cloud. There is no vendor server in the path that could be subpoenaed, mirrored or switched off.
Every device authenticates with a client certificate issued by your own certificate authority, and revocation is yours to enforce.
You run the full QuantorPhone server stack on your own infrastructure — on-premises or in a sovereign cloud. We provide the software and the hardening guide; you hold every key.
Prefer a turnkey installation? Secure Path provisions and deploys the complete server stack on your premises and hands you a running, fully isolated system. You keep exclusive control — nothing leaves your perimeter. Contact us for deployment details.
QuantorPhone is licensed to vetted government, defense and critical-infrastructure organizations. Every capability on this page is included — no tiers, no add-ons.
