About this app

🛡️ CallShield: Intelligent Protection Against Spam and Telemarketing Calls!
Tired of receiving unwanted calls from telemarketers, robocalls, scammers, and unknown numbers that hang up as soon as you answer? CallShield was developed specifically to restore your peace of mind in a completely automatic, offline, and 100% private way.

Unlike other apps that sell your data, CallShield processes everything on your own phone (Local-First). Your contacts, call history, and privacy NEVER leave your device or are shared with cloud servers.

🔥 HOW CALLSHIELD PROTECTS YOU (THE 4 BUSINESS RULES):
1️⃣ Secure Contact List:
If the number calling is in your contact list, CallShield instantly allows the call. Your friends, family, and work contacts can always get in touch with you.

2️⃣ Call History:
Unknown numbers you've answered in the past are remembered and automatically blocked on future calls.
3️⃣ Second Attempt Protection (Emergencies):
Unknown number calling for the first time? CallShield silently rejects it without ringing or bothering you. If the person really needs to talk to you and calls back within 15 minutes, the app understands that it may be urgent and lets it ring!

4️⃣ Automatic Spam and Anatel Blocking:
Immediate blocking of known spam, robocalls, and Anatel-regulated numbers (prefixes 0303 and 0304).
