## Description

🛡️ LinkSentry — Your Invisible Bodyguard While Browsing

LinkSentry automatically protects you from phishing, IP trackers, fake downloads, browser lockers, and fake shops — before you even notice.

━━━━━━━━━━━━━━━━━━━━━━

WHY LINKSENTRY?

Every day, millions of people fall victim to online scams. Scammers are getting more sophisticated — fake websites look identical to real ones, IP loggers hide in harmless-looking links, and fake downloads disguise themselves as popular software.

LinkSentry detects these threats and blocks them at the network level — before your data is ever sent.

━━━━━━━━━━━━━━━━━━━━━━

FREE FEATURES

🔒 Phishing Protection
Automatically blocks 157,000+ known scam sites from 4 daily-updated feeds. Sites are blocked at network level — they never even load.

📍 IP Logger Detection (UNIQUE!)
Detects 70+ known IP tracking services like Grabify, IPLogger, and more. When someone sends you a tracking link, LinkSentry blocks it before your IP address, location, or device data is ever transmitted.

⌨️ Typosquatting Warnings
Detects when you land on a fake domain that looks similar to a known website (e.g., <a href="https://prod.outgoing.prod.webservices.mozgcp.net/v1/59e3980f1936787bbd8217e716a4bc3c2b0caa83dd06677ecc1849dc5dc1c4e7/http%3A//paypa1.com" rel="nofollow">paypa1.com</a> instead of <a href="https://prod.outgoing.prod.webservices.mozgcp.net/v1/801f2dc114a6b7dae60d8c61bc404cb04b87bbe07d86568fcbf599196404332a/http%3A//paypal.com" rel="nofollow">paypal.com</a>).

💾 Download Protection
Pauses suspicious downloads (.exe, .msi, .dmg) from unknown or very new domains and warns you before you open them.

🔒 Browser Locker Protection
Prevents websites from freezing your browser with fake virus warnings designed to trick you into calling a scam hotline.

⚙️ Protocol Blocker
Blocks 45 dangerous protocols (ms-settings, steam, discord, etc.) that try to launch programs on your computer.

🔗 Tab Protection
Automatically prevents websites from manipulating your other open tabs (reverse tabnabbing).

🔔 Notification Blocker
Blocks fake captcha tricks that cause browser notification spam on your desktop.

📋 Clipboard Protection
Blocks automatic clipboard access that wasn't initiated by you.

🏪 Fake Shop Detection
Analyzes online shops for suspicious signals: new domain, missing legal pages, crypto-only payments, extreme discounts.

🔒 Form Protection
Warns you when you enter passwords or credit card data on suspicious sites.

🌐 WebRTC Protection
Prevents suspicious sites from reading your real IP address via WebRTC — even if you're using a VPN.

🖱️ Right-Click Scanning
Right-click any link, then "Check with LinkSentry" — instantly see if it's safe without opening it.

📊 Dashboard
Clean dashboard shows you how many threats have been blocked.
