In-depth safety analysis
This extension requests only two permissions: "activeTab" and "storage". The "activeTab" permission allows it to read and analyze the content of the current page only when you explicitly click the extension icon, which is exactly what a page auditing tool needs. The "storage" permission lets it save your settings locally. This minimal permission set is normal and expected for a general browser extension in this category.
As with any popular browser extension, users should be alert to impersonators. Always verify that the publisher is listed as "Google Ireland, Ltd." before installing. While "activeTab" access is temporary and user-initiated, it can see all page content at that moment, so avoid running audits on pages displaying highly sensitive personal information. The developer declares that the extension collects location data; a careful user may want to understand why a page auditor needs this and review the privacy policy for details.
The fact sheet highlights a perfect Maintenance & Ownership score, indicating the extension is actively maintained and its ownership is clear. The weakest dimension is Publisher & Identity, which scored lower. This could reflect a less robust verification of the publisher's identity in the store listing, reinforcing the need to double-check you are installing the genuine, official version.
AI-assisted analysis of the documented signals above (permissions, store data, privacy practices) — explains what they mean and the risks typical for this category. Not a hands-on test.
What the store listing shows
Who's Behind Lighthouse?
- Publisher Google Ireland, Ltd.
Public records identify the publisher, but no individual founders or a separate registered company are named — which is what holds the Publisher & Identity score back. Less public information about who operates an extension means less you can verify about their long-term accountability.
