Privacy Policy for RF Scanner: TSCM & SDR Radar

Effective Date: August 17, 2026
Last Updated: August 17, 2026

This Privacy Policy describes how our mobile application “RF Scanner: TSCM & SDR Radar” (hereinafter referred to as the “Application”) handles user data and privacy.

As a professional cybersecurity and Technical Surveillance Counter-Measures (TSCM) utility, we hold the highest standards for user privacy. Our core principle is absolute local data processing: No data ever leaves your device.

1. Information Collection and Network Transmission

Zero Network Communication: The Application does not contain any internet communication code, analytics SDKs, or third-party trackers. It operates 100% offline.
No Personal Data Collection: We do not collect, harvest, store, or transmit any personally identifiable information (PII), such as names, email addresses, device IDs, or accounts.

2. Hardware Permissions and Data Usage

To perform its scientific and security analysis, the Application requests specific hardware access. All processed signals are stored strictly in volatile RAM and are completely destroyed when the app or its respective module is closed.

A. Audio Recording Permission (`RECORD_AUDIO`)

Purpose: Required strictly for the Acoustic & Ultrasonic Spectrum Analyzer module to пеленговать high-frequency ultrasonic tracking beacons and microphone jammers.
Handling: The Application captures the raw PCM audio stream using the UNPROCESSED system source. This data is fed directly into a localized Fast Fourier Transform (FFT) algorithm in C++ (NDK).
Privacy Assurance: Raw audio is never saved to the device’s storage, never cached, and never re-transmitted as playable sound.

B. USB Host API and Device Access

Purpose: Required for the External SDR Radio Scanner module to detect and interface with external USB hardware (such as RTL-SDR or HackRF dongles) via USB OTG.
Handling: The App requests a low-level Linux file descriptor via Android’s native UsbManager to pipe raw asynchronous IQ-packet data straight to the native core via ioctl.
Privacy Assurance: No files are created, and no radio traffic logs are archived.

C. Magnetic Field Sensor Access (`Sensor.TYPE_MAGNETIC_FIELD`)

Purpose: Used by the EMF Radar module to analyze electromagnetic anomalies and trace hidden wiring.
Handling: This hardware sensor does not require runtime prompts. The data is filtered locally via a High-Pass Filter (HPF) and visualized on a dynamic 2D canvas chart.

3. Third-Party Libraries and SDKs

To keep the application ultra-compact (under 2 MB) and strictly secure, we do not use any third-party frameworks, advertising networks, or telemetry tools. The code is written purely on native Android SDK and low-level C++.

4. Children’s Privacy

The Application does not collect any data and is safe for all users, but it is an advanced engineering tool not intentionally marketed to children under 13.

5. Changes to This Privacy Policy

We may update our Privacy Policy from time to time. Any changes will be posted by updating the “Effective Date” at the top of this document within the GitHub repository.

6. Contact Information

If you have any academic or technical questions regarding this application’s architecture or data processing, please open an Issue in this GitHub repository or contact the developer directly through the official marketplace console channels.
