Zero Cloud. Zero Accounts. Zero Telemetry.
We believe personal clipboard text, two-factor authentication codes, and notification alerts have no business touching a third-party server.
No Accounts or Profiles
LocalMetro requires no registration, email address, password, or Apple ID. There is no user database, no cookies, and no tracking identifier.
Local-Only Socket Traffic
All data packets travel strictly over your local network interface (Wi-Fi, USB, or Hotspot). Not a single byte of your clipboard or notifications leaves your LAN.
Ephemeral OTP Codes
2FA SMS verification codes extracted on-device are delivered directly to the Mac notification system and purged from memory after 3 minutes.
100% Open Source (MIT)
Every line of code for the macOS SwiftUI app, Android Compose app, and wire protocol schema is publicly inspectable on GitHub.
Architectural Decision ADR-006: No Cloud, LAN Only
The design of LocalMetro is constrained by design document ADR-006:
"LocalMetro shall not introduce external cloud servers, relay endpoints, or user databases in its primary workflow. All discovery and data exchange are bound to local subnet boundaries or direct hardware links."
If you run network packet inspection (such as Wireshark or Little Snitch) on your Mac while using LocalMetro, you will see zero outbound WAN traffic from the LocalMetro process.
