Privacy, sensors, accuracy, and offline use.
No. Field Instruments operates entirely on your device. All calculations and sensor readings happen locally in your browser. No data is ever sent to a server or tracked.
For full functionality, your device needs a Magnetometer (Compass), Gyroscope, Accelerometer, and a Microphone.

Yes. Once the page is loaded, the instruments run entirely client-side. You can disconnect from the internet and continue using the tools.
If the compass reading seems off, move your device in a figure-8 motion a few times. This helps the magnetometer recalibrate to its environment.
