Tired of telemarketing calls, robocalls, and unknown numbers interrupting your day? CallGuardian identifies and blocks unwanted calls silently and automatically — without you needing to change your phone's default dialer.
🔒 HOW IT WORKS
CallGuardian uses the official Android service (CallScreeningService) to analyze each incoming call before it reaches you. If the number is on the block list, the call is automatically silenced and you receive a discreet notification.
✅ MAIN FEATURES
• Automatic blocking of spam and telemarketing calls
• Frequently updated community block list
• Whitelist: ensure your contacts are never blocked
• Custom blacklist: add any number manually
• Blocked call history with date and time
• Notification when blocking, with option to add to whitelist
• Works in the background, without consuming much battery
• Completely offline — your data stays on your device
🛡️ YOUR PRIVACY FIRST
CallGuardian does not send any personal data to external servers. All call logs, rules, and settings are stored locally on your device.
📱 REQUIREMENTS
• Android 7.0 or higher (API 24+)
• In system settings, set CallGuardian as your "Caller ID and spam" app to enable automatic blocking
