Trust & Security

Security isn't a feature. It's the architecture.

Murmly acts on your behalf across your most sensitive tools. We designed it so that local-first is the default, every cloud call is gated and audited, and you can prove exactly what touched the network.

computer

Local-first

Transcription and cleanup can run entirely on-device. Cloud is opt-in.

verified_user

Fail closed

When policy says no network, the cloud client is refused outright — no silent fallback.

receipt_long

Tamper-evident audit

Every action lands in a hash-chained log you can verify on demand.

undo

60-second undo

Every mutating operation is reversible. High-risk actions confirm first.

How your data is handled

Murmly minimizes the existence of your most sensitive data rather than just securing it. Audio is processed and discarded; what's stored is yours and stays on your device by default.

graphic_eq

Audio never persists

Speech is transcribed locally (Whisper / Parakeet) and the audio buffer is dropped immediately. Only text moves forward through the pipeline.

key

Encrypted credential storage

OAuth tokens and account secrets are sealed with the OS keystore (Windows DPAPI, per-user) — never written in plaintext, never bundled in the app.

policy

Network gate on every cloud call

An audited HTTP layer checks policy before any request leaves the process. Blocked calls are logged with the reason — defence in depth, even against our own bugs.

fingerprint

PII-safe logging

Audit rows store SHA-256 hashes of recipients and subjects — enough to prove what happened, never the content itself.

Security controls

Account & access

  • checkEmail verification on every new account
  • checkTwo-factor authentication on sign-in
  • checkArgon2 password hashing
  • checkhttpOnly signed-cookie sessions
  • checkBot protection on auth endpoints

Transport & storage

  • checkTLS 1.2+ for all network traffic
  • checkOS-level encryption for local secrets
  • checkHash-chained, append-only audit log
  • checkConfigurable data retention
  • checkOptional owner-voice biometric unlock

Enterprise & admin

  • checkHierarchical policy (user → org → deployment)
  • checkSigned deployment manifests
  • checkAir-gapped / on-prem mode
  • checkPer-account network & sharing controls
  • checkPlugin sandboxing

Compliance

Murmly's architecture is built toward the controls these frameworks require. We're actively pursuing formal attestations as we scale.
