claw GPS Tracker is a privacy-first location tracking companion for OpenClaw, the open-source AI assistant. Your phone sends encrypted GPS coordinates to your own computer through a zero-storage relay server. OpenClaw can then query your location and movement history — all without any third party ever seeing where you are. HOW IT WORKS • Your phone acquires GPS coordinates at a configurable interval • Coordinates are end-to-end encrypted using X25519 key exchange and AES-256-GCM • Encrypted data is forwarded through a relay server that stores nothing • Only your computer (running gps-bridge) can decrypt and store the data • OpenClaw queries your location locally — no cloud, no external API FEATURES • End-to-end encryption with forward secrecy (new key per message) • Background GPS tracking with configurable update intervals • History recording with adjustable granularity and retention period • Multiple sharing modes: Auto, Ask (coming soon), and Deny • Official relay server included — no setup required • Self-hosting supported for full control • Open source: phone app, relay server, and bridge are all publicly auditable PRIVACY BY DESIGN • The relay server is zero-storage — it only forwards encrypted blobs • Your private key never leaves your computer • GPS data is stored only on your own machine • No account required, no telemetry, no ads • You control exactly when and how often your location is shared SETUP 1. Install gps-bridge on your computer (pip install gps-bridge) 2. Tell OpenClaw: "I want to set up GPS tracking" 3. OpenClaw generates a pairing token and public key 4. Enter them in this app's Settings page 5. Tap Start Tracking — done! REQUIREMENTS • A computer running gps-bridge (Linux, macOS, or Windows) • OpenClaw with the gps-location skill installed Learn more: https://github.com/luna61ouo/gps-tracker-app https://github.com/luna61ouo/gps-bridge
