  Zevr Guard — Network Visibility
  
  Zevr Guard blocks known malware and phishing domains using a daily-updated
  threat list, and shows every third-party tracker and company your browser
  contacts in a popup and live globe view. All matching runs locally in your
  browser; your URLs never leave your device.
  
  ━━━ WHAT YOU'LL SEE ━━━
  
  1. Popup with risk score and live tracker list
     Per-tab risk score, full third-party connection list, and one-tap
     block/allow controls.
  
  2. Side panel with Live Globe
     See where your data is going on a world map, with per-company breakdowns
     and counts.
  
  3. Auto-block screen for malware and phishing
     When you navigate to a known malicious domain, Zevr Guard intercepts the
     request and shows a clear warning before the page loads.
  
  4. Settings panel
     Toggle Malware/Phishing, Advertising, and Tracking categories
     independently, plus add custom block/allow lists.
  
  5. Per-page block history
     See exactly what was blocked on the current page, and which custom rules
     are active.
  
  ━━━ ABOUT THE SCREENSHOTS ━━━
  
  All screenshots use seeded sample data so the popup, side panel, and
  warning UI can be illustrated clearly in a single image. The risk score
  and "Dangerous" status shown for zevrhq.com (our project's own site) are
  demonstration values; in production, every score is derived from the
  actual third-party connections observed on each page. zevrhq.com is not
  classified as malicious and is shown only as a placeholder host.
  
  ━━━ HOW IT WORKS ━━━
  
  - Threat list: daily-refreshed feed sourced from URLhaus and curated lists
  - Tracker identification: 115,000+ signals merged from DuckDuckGo Tracker
    Radar, Disconnect, Ghostery, AdGuard, EasyPrivacy, EasyList
  - Geo / ASN: GeoLite2 (offline, bundled)
  - Matching: 100% local, via Chrome's declarativeNetRequest API
  - No URL upload, no telemetry, no account required
  
  ━━━ PRIVACY ━━━
  
  Zevr Guard does not send your browsing history anywhere. The only outbound
  request is to fetch threat-list updates from our CDN, and that request
  contains no information about you or the sites you visit.
