🚀 ELITE FEATURES FOR TOTAL DEFENSE
Our suite of defense protocols is engineered to give you absolute control over who can reach you:

AI-Powered Spam Filter & Caller ID: Our intelligent, on-device artificial intelligence automatically analyzes incoming call metadata and dialer patterns to predict spam, spoofing, and fraud with up to 99% accuracy.
Fortress Mode (Contacts Only): Activate maximum security! Fortress Mode blocks every incoming call except those from your saved contact list and emergency services. Perfect for complete silence and focus.
Custom Prefix Interceptor: Block entire ranges of numbers instantly. Set custom prefix rules to automatically restrict calls starting with specific area codes, country codes, or business prefixes (e.g., +1-800, 021).
Neighbor Spoof Defense: Stop spammers from tricking you using your own area code. This feature detects and blocks spoofed calls designed to look like they are coming from a friendly local neighbor.
Ghost Ringing Protocol: Exhaust the spammers! This advanced protocol silences the ringer on your device but keeps the connection open on the caller's end, wasting the autodialer's time and resources so they stop calling you.
Global Geoblocking (International Call Blocker): Instantly block all incoming calls originating from foreign countries or specific overseas regions to prevent international toll scams.
Repeated Call Bypass (Emergency Override): Safety is our priority. If an unknown caller tries to reach you 3 or more times within 5 minutes, our system recognizes the potential emergency and allows the call to go through.
High Visibility (Senior Mode): A simplified, high-contrast user interface with larger text and buttons, making call protection fully accessible and easy to navigate for seniors and visually impaired users.
Deep Cloud Intelligence Scan: Access global community threat databases with a single tap to scan reputation scores, view spam tags, and read community threat reports on any unknown number.
🔒 100% PRIVACY-FIRST PROTECTION
No Login Required: Get full access to core spam protection immediately. No accounts, email addresses, or sign-ups required.
Offline Local Processing: Your contacts are kept private. We do not store, upload, or sell your call logs, contacts, or phone numbers to third parties.
