Six monitoring engines.

Each requiring explicit consent. Each independently controllable.

TowerWatch™

Monitors cellular network type, tower switching frequency and encryption status every 5 seconds. Alerts on 2G downgrades and suspicious patterns.

BehaviorShield™

Builds a statistical profile of interaction patterns over 7 days. Flags sessions that deviate significantly from your established baseline.

Clipboard Security

Monitors clipboard for 10 sensitive categories — API keys, passwords, card numbers and tokens. All content masked before logging.

Privacy Monitor

Real-time status of every sensitive permission. Detects active screen recording instantly via UIScreen.isCaptured.

Wireless Scanner

Detects BLE trackers by service UUID — AirTag, Tile, Samsung SmartTag and others — even with no broadcast name.

Network Security

Analyses Wi-Fi environment for open networks and suspicious patterns. All findings clearly labelled as indicative.

Architecture principle

No external data flow.

Security Companion operates entirely on-device. Your security context remains under your control.

There are no servers.

Incident Reporting

When something happens,
you get a report.

Every significant alert generates a structured incident report — plain-English account of what was detected, what it means and exactly what to do next.

Generated entirely on-device. Exportable as PDF. Nothing leaves your device without your explicit action.

Example: TowerWatch™ HIGH — Cellular Network Downgrade alert.
