About Online Compass
A high-precision, zero-telemetry browser compass engineered for outdoor adventurers, maritime sailors, educators, and field navigators.
Why We Built Online Compass
Most digital compass tools found in mobile app stores are cluttered with invasive tracking SDKs, full-screen video ads, and unnecessary subscription paywalls. Furthermore, they frequently demand full device permissions that transmit personal telemetry to remote analytics databases.
Online Compass (newonlinecompass.com) was engineered as an uncompromising, open-web navigation instrument. Designed around the modern W3C DeviceOrientation and Geolocation standards, every angle, heading degree, and geomagnetic declination calculation is computed strictly in your local device memory. We believe orientation tools should be instant, reliable, and completely private.
Core Engineering Pillars
Zero-Telemetry Client-Side Privacy
All magnetometer, accelerometer, and orientation sensor calculations execute purely in client-side volatile memory. No headings, coordinates, or device IDs are ever logged or transmitted.
WMM 2025–2030 True North Precision
Built-in implementation of the World Magnetic Model computes geomagnetic field components and local declination, enabling seamless switching between Magnetic North and True Geographic North.
Offline-First PWA Capabilities
Powered by an integrated Service Worker caching layer. Once opened, the compass continues functioning seamlessly on remote hiking trails, open water, or underground without cellular reception.
Real-Time Bearing Lock & Steering
Lock any target course bearing with one tap. Dynamic visual indicators calculate angular deviation and display instantaneous steering guidance (Turn Left, Turn Right, On Course).
