Why ScamGuard: Link Checker exists
Most dangerous links do not look dangerous at first glance. ScamGuard is built for the moment when a URL, QR code, or browser handoff feels just suspicious enough that you want a second look first.
Check links before opening
Paste a URL from SMS, email, chat, or social media and review risk signals before you tap through.
Review QR links first
Use the camera only when you choose to scan a QR code, then review the discovered link before opening it.
Use Android quick checks
Set ScamGuard as part of your Android link flow to inspect links locally before handing them to a browser.
See AI-assisted signals
A bundled AI baseline and signed model updates help surface suspicious patterns, with full details in AI Mode.
Follow signed risk policy
Risk lists and domain rules are loaded through signed policy updates so checks can improve over time.
Stay in control
History, reminders, announcements, trusted domains, and diagnostics are managed from app settings.
Get a clearer answer before you open a link
ScamGuard combines local checks, cloud reputation, signed risk policy, and AI-assisted review so you can understand the warning signs without needing a security background.
Layered link analysis
Local URL structure, HTTPS, domain, homoglyph, typosquatting, suspicious keyword, shortener, reputation, redirect, and AI-assisted checks work together.
Native Android quick checks
Quick-check handoff, preferred browser selection, and trusted quick-check domains help users review links before opening them.
Private controls
Optional on-device history, local cache, daily caution reminders, app announcements, and diagnostics stay visible and manageable.
Model and policy updates
The app includes a bundled AI model baseline and can fetch signed policy and model updates from MiniFyn infrastructure.
Use it when a link feels off
These are the everyday moments when pausing to check can help you make a more informed decision before opening an unfamiliar destination.
- Unexpected payment or delivery links in SMS
- QR codes on posters, packages, or messages
- Login reset links that seem slightly off
- Offer, lottery, reward, or KYC messages
- Unknown links shared in chats or social posts
- Browser handoffs where you want a quick local warning
Stay in control of your checks
Keep history optional and stored on your device when enabled.
Turn daily caution reminders and app announcements off whenever you choose.
Manage trusted quick-check domains and preferred browser handoff settings from the app.
