Extension Metadata
About this extension
🛡 PhishGuard AI — phishing protection that keeps your data on your device.
Most anti-phishing tools send every link you touch to someone else's server. PhishGuard flips that: a trained AI model is bundled INSIDE the extension, so every scan runs locally. Fast, private, and fully functional offline.
WHAT IT DOES
• 🔗 URL Scanner — popup verdict (Safe / Suspicious / Phishing) with risk score and plain-language reasons
• ✉📱 Message Scanner — paste any email or SMS; catches OTP scams, urgency bait, prize fraud and spoofed senders
• 🛡 Auto-Protect — red warning banner on flagged pages, amber badge on suspicious ones, silent when safe
• 🖱 Right-Click Scan — check any link without visiting it
• 🤍🖤 Trust Lists — your own always-safe and always-blocked domains
• 📊 Stats Dashboard — scans per day, threat breakdown, weekly block count
WHY IT'S PRIVATE BY DESIGN
• The AI model ships inside the extension — analysis never leaves your machine
• No account, no analytics, no trackers, no remote scripts
• Works with Wi-Fi off — everything is local-first
HOW TO USE
1. Install — no signup, nothing to configure
2. Browse normally — threats are flagged automatically
3. Right-click any link to pre-scan it safely

The ONNX model and all analysis run entirely locally - the extension makes no
network requests for analysis. Data collection is declared as "none" in the
manifest (browser_specific_settings.gecko.data_collection_permissions).
