Private Fraud Notifier
A scammer keeps you on the phone while you "just check your balance." PFN catches that — alerting you the moment a banking or remote access app opens during a call. Everything runs on your device. Nothing leaves it.
See it in action
Scenario 1 — Banking scam
Someone calls claiming to be your bank. They keep you talking while asking you to "just confirm your balance." The moment you open your banking app, PFN fires an alert — before you hand over a single digit.
Scenario 2 — Remote takeover
A caller convinces you to install AnyDesk or TeamViewer for "technical support." The moment that app opens, PFN alerts you — whether you're on a call or not. Remote desktop fraud is one of the fastest-growing attack vectors, and PFN is the only app that watches for it.
How it protects you
Call + app detection
Watches for banking and payment apps opened while a call is active. No screen sharing required — a call alone is enough to trigger protection.
Remote desktop alerts
Detects AnyDesk, TeamViewer, and similar remote access tools the moment they open. With paranoid mode, this works even when you're not on a call — because sometimes the setup happens before the fraud does.
82-country coverage
Ships with a curated list of banking apps from 82 countries. Protection works out of the box, worldwide — no setup, no configuration, no partner opt-ins required.
100% on-device. Zero telemetry.
PFN processes everything locally. Your calls and app usage never leave your phone. There is no server receiving your data, no cloud analysis, no account required. The protection is entirely self-contained.
