eng-pad-server

Read-only sync and web viewer for eng-pad engineering notebooks.

The Android app pushes complete notebooks to this server via gRPC. The server stores them and serves read-only views through a web UI with SVG rendering. Shareable links allow unauthenticated access to specific notebooks.

Features

• gRPC sync: receive notebook data from the Android app over TLS
• Web viewer: browse notebooks, view pages as SVG, export JPG/PDF
• Authentication: password (Argon2id) + FIDO2/U2F security keys
• Shareable links: token-based URLs with optional expiry
