Url Check - LinkGuard

LinkGuard — Link Safety Assistant

Ever clicked a link and wondered where it actually leads? LinkGuard sits between your apps and your browser, giving you full control over every URL before it opens.

🛡️ WHAT LINKGUARD DOES
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

When you tap a link in WhatsApp, Gmail, Telegram, Instagram, SMS, or any other app — LinkGuard intercepts it first. In seconds, it analyzes the URL, shows you a trust score, and lets you decide what to do next.

No more blindly opening suspicious links. No more being tracked across the web. No more phishing surprises.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
🔍 POWERFUL URL ANALYSIS
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Every link is analyzed instantly for:

- HTTPS vs HTTP — know if your connection is encrypted
- Domain validation — detect lookalike and spoofed domains
- Suspicious characters — catch Unicode and homograph attacks (googlе.com vs google.com)
- Redirect chains — follow redirects to reveal the true destination
- Tracking parameters — detect utm_source, fbclid, gclid, and 20+ more trackers

A clear Trust Score from 0–100 tells you exactly how safe a link is, color-coded Green, Amber, or Red.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
🧹 URL CLEANER
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Tracking parameters follow you everywhere. LinkGuard removes them with one tap.

Before: https://shop.com/product?id=123&utm_source=facebook&fbclid=abc&utm_campaign=sale
After: https://shop.com/product?id=123

See a visual before/after comparison with every removed parameter highlighted. Copy, share, or open the clean URL directly.

📷 QR CODE SCANNER
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Don't trust unknown QR codes. Scan any QR code with LinkGuard and the URL is automatically analyzed before anything opens. Supports flashlight toggle for scanning in low light.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
🌐 BROWSER CHOOSER
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

Open any link in your preferred browser — Chrome, Firefox, Brave, Edge, DuckDuckGo, Samsung Internet, or your system default. You stay in control of where links open.

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
📋 HISTORY & SEARCH
