SWIS SPhone

SWIS SPhone is an Android privacy dialer app with built-in behavior-based scam protection designed to act as an on-device line of defense for active phone scam protection and deceptive caller defense.

Unlike traditional spam call blockers that rely on outdated database files, SWIS SPhone evaluates interaction patterns locally.

The system provides real-time fraud prevention by analyzing subtle behavioral signals and call interaction dynamics during live calls.

Key Features: • Behavioral Intelligence Engine: Analyzes mobile caller interaction patterns and protects against psychological manipulation in real-time. • Two-Stage Warning System: Uses a system-level safety alert interface (yellow/red visual overlays). • Full Phone Dialer: Minimal, lightweight, built with Jetpack Compose. • Privacy-First Design: Zero cloud, zero analytics, and fully offline. All processing happens locally on your hardware. • No Call Recording: Prioritizes user consent and legal privacy by never monitoring or recording voice audio. • Call Metadata Export: Generates secure offline PDFs with important call metadata (Document) without compromising audio privacy.
