SpyGuard

SpyGuard is the most honest counter-surveillance suite on the Play Store.

9 detection modules that use REAL technology to find hidden cameras, microphones, trackers, and malicious cell towers. Unlike other apps that invent fake threats to scare you into paying, every SpyGuard finding is backed by evidence: real network packets, sensor data, FFT spectra, and radio samples.

==== 9 INDEPENDENT MODULES ====

- NETWORK RECONNAISSANCE: ARP sweep + scanning of 14 camera ports (RTSP 554, Hikvision 34567, Dahua 37777, ONVIF 8899) + HTTP fingerprinting against a database of 17 manufacturers (Hikvision, Dahua, Axis, Foscam, Reolink, TP-Link Tapo, EZVIZ, Wyze, Ring, Arlo, Ubiquiti, Yi, Eufy, Swann, Amcrest, Vivotek, Uniview).

- EMF SWEEP: Real-time magnetometer reading, auto-calibration, haptic vibration alerts for anomalies. Detects hidden motors, coils, and speakers by their magnetic signature.

- IR DETECTION: Your camera detects the 850nm infrared LEDs used by hidden cameras for night vision. Turn off the lights and the app highlights the purple/white dots.

- BLE INTERCEPTION: Specifically detects AirTag (Find My 0x004C), Tile (0x00E0), Samsung SmartTag (0x0075), and Chipolo (0x049A). Measures RSSI proximity to identify devices that are tracking you.

- AUDIO SWEEP: True FFT at 48 kHz + dedicated 18-22 kHz ultrasonic band monitor. Detects carriers from covert wireless microphones.

- WIFI RECONNECT: Detects rogue APs/malicious twins, camera SSID patterns (CAM-###, IPCAM-*, FOSCAM-*, HIKVISION-*), and manufacturer OUI matching.

- REFLECTION HUNTING: Turn on the flashlight and the app detects circular backreflections from hidden lenses in the room.

- CELL RECONCILIATION: Passive heuristic IMSI catcher detector (Stingray type). 8 checks: PLMN mismatch, RAT drop (4G to 2G), implausible Cell ID, isolated towers, transient cells.

- SWEEP MODE: The main protocol. Executes the 8 modules sequentially in 12 phases, generates a security score from 0-100, and a forensic report exportable to JSON or HTML.

==== HONEST BY DESIGN ====

- 100% offline operation. No accounts, no telemetry.

- If the app says CLEAN, it's clean. If it says ALERT, investigate.

- Each detection uses real Android APIs and standard protocols.

- Limitations documented within the app itself (total honesty).

==== 15-STEP INTERACTIVE TUTORIAL ====

The HELP button and the MOD_09 card launch a step-by-step briefing that teaches you each module with visual highlighting on the interface and automatic scrolling.

==== COMPLETE FILE + FORENSIC EXPORT ====

All scans are saved in a local database. Review past sessions, detect NEW devices that weren't there yesterday (the number one red flag), and export JSON/HTML reports.

=== INSTANT BILINGUAL SUPPORT ====

Spanish and English with a selector within the app. Switch instantly, without restarting.

==== USE CASES ====

- Hotels, Airbnb, Booking.com, and tourist accommodations

- Rental cars and ridesharing services

- Offices, meeting rooms, fitting rooms

- Suspected stalking or harassment

- Professional privacy audits

==== LIMITATIONS (we'll tell you from the start) ====

- Cannot decrypt cellular traffic (requires baseband access)

- Does not detect silent SMS messages (requires system privileges)

- Possible false positives on trains, at airports, and in remote areas (documented in each module)

NO ADS IN THE MODULES. NO SELLING OF YOUR DATA. NO TRACKING.
