What this extension helps you do

Locally analyze what a website can access, store, and transmit through a clear technical privacy report.

Privacy Lens locally analyzes the active website to explain what browser-visible data the site can access, store, and transmit. It presents the results as a clear privacy report, including trackers, cookies, external domains, permissions, network activity, and practical privacy recommendations.

Local processing and privacy

The extension processes the following information only as described for its visible product workflow:

  • When you start an analysis, Privacy Lens examines browser-visible properties of the active website, including page characteristics, forms, fingerprinting signals, and exposed device or browser information.
  • It inspects cookies and site-storage metadata associated with the active website so it can distinguish first-party and third-party storage and identify potential tracking or persistence risks.
  • It observes request metadata such as destinations, resource types, timing, and first-party or third-party status to identify trackers, analytics services, external domains, and potential data-exfiltration patterns. It does not send request contents to external servers.
  • It reads relevant browser content and permission settings and monitors navigation events so each report stays associated with the correct page.

No user data is transmitted to IHOR.DEV or third parties.
