CallGuard: Bloqueio de Spam

Tired of telemarketing calls, scams, and unknown numbers? CallGuard blocks unwanted calls before your phone even rings.

Everything works directly on your device: your calls are analyzed locally, without registration and without sending your numbers to servers.

AUTOMATIC PROTECTION
CallGuard analyzes each incoming call and assigns a risk score. Suspicious numbers can be silenced, and spam is automatically rejected without you having to do anything.

BLOCK ANY NUMBER
Type the number or choose directly from your contacts. Organize by category: scams, telemarketing, debt collection, and others.

VIP LIST
Family, doctor, school, and work can always reach you. Numbers on the VIP List are never blocked, even with maximum protection enabled.

HISTORY AND REPORTS
See all calls that have been analyzed, blocked, or silenced. Report scams and telemarketing calls with one tap so the number is blocked next time.

STATISTICS
Track how many calls were analyzed, blocked, and marked as suspicious.

BLOCKING ALERTS
Receive a notification whenever a call is rejected, so you don't miss anything important.

HOW IT WORKS
1. Open CallGuard and tap "Activate protection".

2. Choose CallGuard as your call filtering app.

3. Done! Unwanted calls will now be blocked automatically.

REQUIREMENTS
Automatic blocking requires Android 10 or higher, which is when Android started allowing call filtering by other apps.

Note: Due to an Android rule, contacts saved in the address book are not filtered. To block a saved contact, use the "Block in system" option within the app.
