Privacyscope

Know what your browser extensions can really access — before and after you install them.

PrivacyScope scans every installed Chrome extension and scores it based on its declared permissions. Dangerous combinations are
flagged in plain English, not technical jargon. No more wondering what "access your data on all websites" actually means.

🔍 WHAT IT DOES

• Scans all installed extensions and assigns a risk score
• Translates permission names into plain English ("Can read every page you visit", "Can access your login sessions")
• Detects AI-powered extensions that may send your page content to external servers
• Shows a risk badge on the Chrome Web Store before you install anything new
• Alerts you when an extension has gained new permissions since your last scan
• Lets you mark trusted extensions to reduce noise

🛡️ HOW IT WORKS

Every Chrome extension ships with a public manifest listing the permissions it requests. PrivacyScope reads this using Chrome's own management API — the same data source as chrome://extensions. We score each permission based on its potential for harm and explain it in plain English.

🔒 YOUR PRIVACY

PrivacyScope never reads your web page content and makes no external requests to any server we operate. All analysis runs locally
on your device. The only external connections are to Google's own extension download servers (the same ones Chrome uses to install extensions) when scanning a Chrome Web Store page.

📋 PERMISSIONS EXPLAINED

• management — reads your installed extensions and their declared permissions
• storage — saves scan results and your trusted extension list locally
• webNavigation — detects Chrome Web Store visits to show the pre-install badge
• Google CDN hosts — downloads extension packages for pre-install analysis

⚠️ IMPORTANT LIMITATION

PrivacyScope shows what extensions could access — not what they are actively doing. A high score means you should investigate, not panic. uBlock Origin scores "Review recommended" because it genuinely has broad access. That's intentional and fine.
