Architecture you can audit

Engineers pick tools they can reason about. Here's where your data actually lives.

verified

Zero-knowledge cloud Vault

Connection secrets are encrypted client-side with PBKDF2-derived keys before they touch our servers. We literally cannot read them.

verified

OS keychain, not localStorage

Desktop credentials live in the platform keychain via Electron safeStorage (macOS Keychain / Windows DPAPI / libsecret).

Your MongoDB data never reaches us

Desktop talks straight to MongoDB. The web client routes through a thin connection-pooling proxy that only sees the operations you initiate.

Crash reports stay on your machine

Native crashReporter writes minidumps locally — no automatic upload. You attach them to a bug report when (and only when) you choose to.

Spanna data flow The Spanna app on your machine sends only encrypted connection blobs to Spanna cloud (vault + auth). Spanna cloud never receives plaintext MongoDB credentials and never connects to your MongoDB. The Spanna app talks directly to your MongoDB over TLS, with an optional SSH tunnel for the web client. encrypted connection blob never no plaintext Spanna app (your machine) Spanna cloud (vault + auth) Your MongoDB (your servers) direct connection · TLS · optional SSH tunnel for the web client your data flows here, never through the cloud
