MAGPRO PRIVACY POLICY

Last Updated: March 2026

📊 Data Collection and Storage

MagPro processes raw magnetic field data retrieved directly from your device's magnetometer sensor. Our application operating principles are strictly built on user privacy:

• ✓ Local Processing Only: All magnetic field measurements are processed directly on your local device.

• ✓ No Cloud Servers: We do not transmit, upload, or store any of your scanning data on external cloud servers.

• ✓ Zero Personal Data: MagPro does not collect, request, or store your personal information (such as name, identity, e-mail address, or real-time location).

• ✓ No Third-Party Sharing: Since no data is collected, absolutely no information is shared with or sold to third-party entities.

📱 Data Stored on Your Device

Your magnetometer sensor measurements are saved exclusively on your own hardware so you can review your history, export CSV data, and perform professional analysis:

• ✓ Scan date, timestamp, and duration

• ✓ Raw magnetic field values ($X, Y, Z$ vectors and total field $B_0$ in microTesla $\mu\text{T}$)

• ✓ Your custom sensor configuration and grid settlement settings

Data Ownership Rules:

• These data structures belong strictly and solely to you.

• All files remain locked within your local device directory.

• Zero Footprint: Uninstalling the app completely wipes all stored scan data from the hardware.

• No data can be accessed, viewed, or intercepted by MagPro technical engineers.

🛰️ Location Information and Device Permissions

MagPro 3D Magnetometer is an advanced underground geophysical analysis software.

To transfer local magnetic scan logs wirelessly via Bluetooth (BLE) to the PC Analysis Engine, Android OS operating protocols strictly require "Nearby Devices" and "Location" permissions.

🔒 Strict Offline Rule: MagPro absolutely never records, tracks, or transmits your actual geographic GPS coordinates. The background permission is strictly used for wireless hardware communication interfaces. The software operates 100% offline and leaves zero network traces.

⚙️ Required Permissions

Our system requires specific hardware permissions to access the magnetic sensor matrix and establish wireless (Bluetooth BLE) handshake protocols with custom MagPro hardware configurations:

• Bluetooth & Location Framework: Required by Android standard deployment guidelines to discover and bind with wireless hardware modules.

• Zero Surveillance: No monitoring, background analytics, or invasive trackers are implemented.

• No Unnecessary Access: The application will never request permissions for unrelated components like your camera, contacts, or microphone.

🛡️ Cyber Security & Data Integrity

Since your measurement architecture is locked on your own mobile unit:

• Data integrity relies entirely on your device's built-in cryptographic security layer.

• No automated remote backups are performed (unless explicitly managed by your overall device image backup).

• Zero network exposure ensures full protection against digital data interception.

📝 Amendments and Policy Updates

Any future structural adjustments or official updates to this privacy policy framework will be directly published and made transparent on this official portal page.
