Zero-knowledge architecture
We cannot see what we're not given the keys to decrypt. Keys are derived between your devices and never leave them — even a court order couldn't produce a copy we don't hold.
Remio's zero-knowledge architecture means we can't see your data — even if we wanted to. No account, no middleman, nothing stored.
Zero-knowledge is a property of how Remio is built — not a policy we ask you to trust.
We cannot see what we're not given the keys to decrypt. Keys are derived between your devices and never leave them — even a court order couldn't produce a copy we don't hold.
No email, no password, no user database to breach. When AnyDesk was breached in 2024 and TeamViewer hit by APT29, they had credentials to lose. Remio has nothing on file.
Your data flows directly between your devices. The connection server only performs the handshake; when a relay is unavoidable it forwards packets it cannot read.
AES-256-GCM authenticated encryption — the same standard that guards banking and government traffic. Brute-forcing it would outlast the age of the universe.
Every session derives a fresh, single-use ephemeral key, destroyed when you disconnect. Past sessions stay protected even if a future key leaks.
A 4-digit PIN you read off the host screen authorises a device, not an identity — valid for minutes, single-use, closer to an in-person key exchange than an account.
Your OS protects Remio's secrets with its own hardware — Secure Enclave on Apple, secure elements on Android, the trust chip on Windows. Nothing extractable without unlocking the device.
Public FlatBuffers schemas are the single source of truth — the exact binary format is reproducible, generating the same code for iOS, macOS, Android, Windows and the Go server. No proprietary black boxes.

The honest test of any remote-desktop tool is what a break-in exposes. With Remio, the answer is nothing.
| Dimension | Remio | AnyDesk / TeamViewer |
|---|---|---|
| Stream routing | Direct peer-to-peer | Through vendor servers |
| Account required | None — PIN only | Yes, email + password |
| Can the vendor decrypt? | Impossible by design | Technically possible |
| What a breach exposes | No user data to leak | All users (2024 incidents) |
| Past-session protection | Perfect forward secrecy | Unclear |
| Protocol audit | Public schemas | Proprietary, closed |
| Telemetry | None — zero | Usage + device analytics |
The stream is protected with AES-256-GCM for confidentiality and integrity, ECDHE over Curve25519 for key exchange, and DTLS-SRTP for transport — the same key-exchange family behind Signal, WireGuard and modern HTTPS. Session keys live only in memory, for the length of a session, then vanish.
No telemetry, no cookies, no analytics — GDPR-compliant by architecture, not by policy page.

Some protections are already in place; others are on the way. We only claim what we can prove.
No personal data is collected, so there is nothing to protect — plus rate-limiting at the signalling edge, platform secure-vault storage on every device, and an open protocol anyone can verify.

The same zero-knowledge design that protects a single Mac scales cleanly to a handful of paired devices. Because Remio has no central account store, there's nothing to provision and nothing to leak — every pair of devices holds its own keys. We're an independent project, so we don't yet offer enterprise support, SOC 2 attestation, or SLAs; what we do offer is an architecture you can verify yourself through the open protocol and whitepaper.
