Guardião Avoker

🦅 AVOKER GUARDIAN — active protection against digital scams

Avoker Guardian is the Brazilian ACTIVE PROTECTION app for users
over 55 years old. While other apps only alert you AFTERWARDS, Guardian acts
BEFORE — analyzing suspicious messages, identifying scam calls and
preventing access to malicious websites.

✨ THE 3 BARRIERS OF PROTECTION

🛡️ 1. Message Analyzer
Received a suspicious WhatsApp, email or SMS (fake INSS, fake bank,
fake refund)? Copy the text and paste it into Guardian. In seconds you see a report with risk level, identified scam patterns and action recommendation. Analysis done LOCALLY on your cell phone — nothing is sent to external servers.

🛡️ 2. Caller ID
Received a call? The Guardian checks the number against our collaborative database and displays "Known / Suspicious / Unknown" during the call. It automatically blocks reported numbers.

🛡️ 3. DNS Shield (Local VPN)
The Guardian uses the Android VPN service to create a LOCAL connection ONLY within your device — it's not a commercial VPN, it doesn't redirect your traffic to remote servers. Each domain query is compared with a daily updated list of malicious websites, and fraudulent domains are blocked before the browser accesses them. All filtering happens offline, on the phone itself.

✨ EXTRA FEATURES

🆘 Emergency SOS
Fullscreen panic button on the lock screen. Alerts registered family with your current location in seconds.

👨‍👩‍👧 Family Map with Investigative HUD (opt-in)
View the shared location of up to 5 family members on a map with a gold command center-style interface. Each member needs to accept manually. No background tracking — only when the app is open.

Distance, last update, and status of each family member in real time.

🔬 Media Forensics Engine
Received a suspicious image? Share it with the Guardian and see:

• EXIF ​​metadata analysis
• ELA (Error Level Analysis) to detect tampering
• Detection of known watermarks
• Deepfake detection (embedded model)
• Locally generated PDF report

📞 Call Overlay
Native visual identifier over the call screen (Truecaller style), showing if the number is known or suspicious, with buttons to block, trust, or report — functional in real calls.

🏦 Banking Mode
Detection of open banking apps with extra protection against overlapping malicious apps.

🔔 Educational Alerts
Weekly notifications with digital security tips and new scams circulating in Brazil.

🔒 PRIVACY — ALL LOCAL

• Message analysis is done 100% on your phone
• Call history is never sent to external servers
• DNS Shield does not relay traffic — only local domain filtering
• Full compliance with LGPD (Brazilian General Data Protection Law)
• Export your data in JSON or delete your account at any time
• You can revoke any permission at any time
• Permanent indicator in settings shows what is active
• FLAG_SECURE active: sensitive screens do not appear in screenshots

🛡️ WHY GUARDIAN IS DIFFERENT

Most Android antivirus programs are imported and don't know about Brazilian scams. The Guardian was created HERE, focused on the scams that most affect Brazil:

• Fake INSS (Brazilian Social Security Institute) requesting re-registration
• Fake Detran (Brazilian traffic department) fine using PIX (Brazilian instant payment system)
• Fake relative asking for money
• WhatsApp cloning
• Fake Federal Revenue Service refunds
• Romance scams and fake investments

👥 WHO IT'S FOR

• People over 55 years old
• Children and grandchildren worried about their parents and grandparents
• Families who want complete protection on all devices
• Those who have already fallen victim to scams and want an active barrier

Some advanced functions (Call Screening, DNS Shield) require Android 10 or higher.

⚠️ IMPORTANT: The Guardian is an auxiliary protection tool and DOES NOT replace public security agencies. In case of a scam, file a police report online or call 190 (Brazilian emergency number). Forensic reports generated are INDICATIVE and do not replace official expertise.
