Privacy Policy
Effective Date: July 18, 2026
This Privacy Policy governs the EMF Detector mobile application (the "Application") for Android devices. The Application provides electromagnetic field (EMF) detection using the hardware sensors built into your mobile device.
1. Information Collection and Use
Hardware Sensor Access
The Application requires and accesses the following hardware sensors on your device in real-time to function:
Magnetometer (Compass): To measure electromagnetic fields and magnetic field strength.
Accelerometer: To assess device movement and orientation for accurate detection.
Network and Internet Access
The Application requests internet permission (android.permission.INTERNET) solely to connect with Google Play Services. This connection is required to verify product availability, update pricing, and securely process optional in-app support.
Foreground Service & Background Processing
To ensure uninterrupted real-time EMF monitoring, the Application utilizes a Foreground Service (EMFSensorService). This service runs continuously in the background, allowing the Application to log and process sensor data even when the device screen is turned off or when you are using other applications.
This background processing is classified under the Special Use foreground service type specifically for continuous EMF sensor data logging.
2. Detection Modes and User Configuration
The Application features an interactive, minimalist user interface with four distinct operational modes:
Electronic Device Mode: For detecting standard EMF emissions from everyday electronic appliances.
Paranormal Activity Mode: Designed for use in empty spaces far from electronics, featuring an amplified sensor sensitivity up to 5 times (5x) its base strength.
Strong Magnet Mode: Configured for detecting high-intensity magnetic fields from strong permanent magnets or specialized equipment.
Wall Electrical Cable Mode: Optimized for scanning walls to trace active, live electrical wiring hidden behind surfaces.
User Control: You have full control to manually adjust the signal strength parameters (Gain) for each specific detection mode to suit your immediate environment.
3. Data Storage, Retention, and Security
Zero Server Transmission: The Application does not collect, harvest, or transmit any personal data, sensor logs, or configuration settings to any external servers or online cloud infrastructure.
Local Storage Only: All application configurations, sensor configurations, and recorded data are saved strictly within a local SQLite database residing securely on your physical device.
Automatic Deletion: All locally stored application data is entirely and permanently deleted from your device automatically when you uninstall the Application.
4. In-App Purchases and Financial Data (New)
The Application offers an optional In-App Purchase feature ("Belikan Saya Secangkir Kopi" / "Buy Me a Coffee") to support the independent developer.
Payment Processing: All financial transactions, payments, and billing are handled directly and securely through the Google Play Billing System.
Data Collected: The Application collects Purchase History (specifically transaction confirmation tokens provided by Google Play) solely for App Functionality to verify and unlock your purchase.
Data Security: The developer does NOT collect, store, or access your credit card details, bank accounts, or credentials. All payment processing is managed strictly by Google.
Third-Party Policy: Google Play processes your transaction data in accordance with its own Privacy Policy. The Application only receives a temporary secure confirmation token from Google Play to verify that the support purchase was successful.
5. Disclaimers & Accuracy
Scientific Affiliation Disclaimer
The developer of this Application is an independent entity and is not affiliated, associated, authorized, or endorsed by any official scientific research group, academic institution, or official regulatory research organization.
Accuracy of Measurements
Measurements and data displayed in the Application are for informational and informational-entertainment purposes only and are not 100% accurate. The measurement accuracy depends entirely on:
The hardware quality, calibration, and technology chip limits of the built-in magnetometer sensor inside your specific device.
The manual Gain (amplification) parameters configured by the user.
Environmental variables, natural magnetic anomalies, and localized electromagnetic interference surrounding the device at the time of testing.
6. Changes to This Privacy Policy
This Privacy Policy may be updated from time to time. You are advised to review this policy periodically for any changes. Changes to this Privacy Policy are effective when they are posted within the Application or its distribution platform.
