Private Fraud Notifier

About Private Fraud Notifier

Private Fraud Notifier protects you from phone scams and social engineering attacks — entirely on your device.

HOW IT WORKS
When you receive a phone call and open a sensitive app (like your banking or crypto wallet app), PFN alerts you that you may be under a social engineering attack. Scammers often keep you on the phone while instructing you to transfer money or share credentials.

ACCESSIBILITY SERVICE USAGE
Private Fraud Notifier uses Android's Accessibility Service solely to detect which app is in the foreground while a phone call is active. This is the only way Android allows an app to monitor foreground app changes in real time. The Accessibility Service is never used to read screen content, interact with other apps, collect personal data, or perform any action other than detecting the currently active app. No data collected via the Accessibility Service is stored or transmitted off-device.

KEY FEATURES
• Real-time fraud detection during phone calls
• Alerts when sensitive apps are opened during calls
• 100% on-device processing — your data never leaves your phone
• No account required
• No ads, no tracking

FREE & PREMIUM
Core fraud detection is free. Upgrade to Premium for advanced features including detailed fraud alert history.

PRIVACY FIRST
All analysis happens locally on your device. No personal data is collected or shared with third parties. The only network communication is for subscription verification through Google Play.
