Summary

SEO Lens is a browser extension that audits the SEO metadata of the webpage you are viewing. It runs entirely in your browser. There are no analytics, no trackers, no accounts, and no third-party services involved in normal operation.

What the extension does

When you open the side panel, SEO Lens fetches the HTML of the currently focused tab’s URL and parses it locally to compute the audit. The only network request the extension issues is this fetch of the page you asked it to audit. Audit results, findings, and any copied text are produced and kept on your machine.

Data we collect

We do not collect personal information, browsing history, website content, credentials, location, or financial data. Audit output is not stored on any server and is not transmitted anywhere.

The only exception is the optional feedback form: if you choose to send feedback, your message (and email address, if you provide one) is forwarded to the developer so we can respond. Nothing else leaves your machine.

Permissions

  • activeTab — read the URL of the focused tab so it can be audited.
  • sidePanel — render the extension UI in Chrome’s side panel.
  • tabs — detect tab switches to re-run the audit on the new page.
  • webNavigation — detect full page loads and SPA navigations so audits stay in sync with the page content.
  • host permission <all_urls> — fetch the HTML of whichever page you are currently viewing. You control which page is audited by choosing which tab is active.

Remote code

SEO Lens ships all JavaScript bundled at build time. It does not use eval, does not inject remote scripts, and does not load code from a CDN at runtime.

Third parties

We do not sell or transfer user data to third parties. We do not use user data for creditworthiness or lending. We do not use user data for any purpose unrelated to the extension’s single purpose of auditing SEO metadata.

Open source

SEO Lens is MIT-licensed. Source is available at github.com/Mark-Life/seo-lens.
