Transport
- Paired Macs: end-to-end encrypted. The relay only forwards ciphertext.
- Standalone macOS or Linux Host: authenticated TLS to the control plane, which can see relayed terminal traffic. Not end-to-end encrypted.
Secrets
- Desktop credentials: macOS Keychain.
- Browser peer keys: non-extractable Web Crypto keys in IndexedDB.
- Provider credentials: server-side only, never returned by settings responses.
Your part
Secure Host accounts and disks, keep dependencies current, revoke lost devices, keep backups and review agent output. Outirl is not a backup service.
