Last updated: March 19, 2026
Short version: Detect Metal does not collect, store, or share any personal data. All sensor data is processed entirely on your device and never leaves it.
Overview
Detect Metal ("the App") is a sensor utility application for iPhone. This Privacy Policy explains how the App handles information in connection with your use of the App.
Data We Do Not Collect
We do not collect, transmit, store, or share any of the following:
- Personal information (name, email, phone number)
- Location data
- Device motion or sensor data
- Usage analytics or crash reports
- Advertising identifiers
- Any other data of any kind
Sensor Access
The App requests access to the following device sensors. All data from these sensors is processed locally on your device in real time and is never stored or transmitted.
Location (Compass)
The App requests "When In Use" location permission solely to access the device's magnetic heading (compass bearing). This data is used only to display the compass direction on screen. No location data is ever recorded, stored, or sent anywhere.
Motion & Gyroscope (Spirit Level)
The App accesses the device's accelerometer and gyroscope to display the tilt angle on the spirit level screen. This data is processed in real time on your device and is never stored or transmitted.
Magnetometer (Metal Detector)
The App accesses the device's built-in magnetometer to detect changes in the magnetic field around the device. This data is processed entirely on-device in real time and is never recorded or transmitted.
Internet Access
The App does not require or use an internet connection. No network requests are made by the App.
Third-Party Services
The App does not integrate any third-party SDKs, analytics services, advertising networks, or any other external services.
Children's Privacy
The App does not collect any information from anyone, including children under the age of 13.

If we make material changes to this Privacy Policy, we will update the "Last updated" date above. Since we do not collect any data, changes are expected to be minimal.
