VellumDoc performs no network communication for document processing or licensing. No content, usage data or telemetry is transmitted at any time. This isn't a setting — it's the architecture.
The application has no code path that uploads, syncs or transmits your files. Processing happens entirely on the local processor.
Text under a redaction is stripped from the file itself and re-checked to confirm it's gone — not hidden behind a black rectangle.
Licence and application state are held in AES-256-GCM encrypted storage, keyed per install so a copied state file can't be reused elsewhere.
Licences are Ed25519-signed files verified with local mathematics. The app holds only the public key and cannot forge or phone home to validate.
Installed on managed or personal machines; runs with no outbound connections for document work.
Fully isolated networks. Activation happens off-machine and the signed licence is carried in — the protected endpoint never touches the internet.
For enterprises that want licence management inside their own perimeter, with no vendor dependency at activation time.
