Watchdog — Extension Auditor & Manager

Extensions can read your data and change permissions silently. Watchdog audits every extension, alerts you, and puts you in control.

Watchdog monitors every Chrome extension installed in your browser — their permissions, risk levels, network activity, and behaviour changes. It alerts you the moment something suspicious happens and gives you complete control. WHY THIS MATTERS Extensions are powerful software running inside your browser with access to your tabs, history, cookies, and every website you visit. Most users have no idea what permissions their extensions have or when those permissions quietly change after an update. Watchdog makes that visible. FREE FEATURES ✓ Full permission audit for every installed extension ✓ Risk scoring — Low, Medium, High — based on actual permissions ✓ Plain-English explanations of what each permission actually means ✓ Instant alerts when a new extension installs ✓ Alerts when an extension gains new permissions after an update ✓ Browser health score showing your overall exposure ✓ Dormant extension detection — flags unused extensions that still hold sensitive permissions ✓ Third-party cookie blocking toggle PRO FEATURES — 14-day free trial, no credit card ✓ Quick disable and enable any extension directly from the popup ✓ Extension profiles — create Work, Research, Gaming groups and switch with one tap ✓ Scheduled profile activation — auto-activate profiles on a time schedule ✓ Custom risk rules — whitelist trusted extensions or force your own risk thresholds ✓ Permission change timeline — full history of every permission change per extension ✓ Alert history with search, filter by type, and CSV export ✓ Extension comparison — side-by-side permission diff between any two extensions ✓ Monthly audit digest — full PDF report of your extension landscape ✓ Tracking parameter stripping — removes UTM, fbclid, gclid and 30+ tracking tags from URLs PRIVACY FIRST All monitoring happens entirely on your device. Watchdog makes zero network calls during normal use. No account required, no telemetry, no data ever sent anywhere. The only exception is license validation — which sends only your license key to our server, nothing about your extensions or browsing. Learn more at localext.com/watchdog
