SEO Stack Insights — Browser Extension · Last updated: June 28, 2026

In short: SEO Stack Insights does not collect, transmit, sell, or share any of your data. All analysis happens locally in your browser, on the page you choose to audit, and the results stay on your device unless you export them yourself.

1. What This Extension Does

SEO Stack Insights is a browser extension that analyzes the web page you are currently viewing — when you click the extension icon and run an audit — to surface SEO, technical, structured-data, AI-visibility, and technology-stack information about that page. All of this analysis runs inside your browser.

2. Data We Collect

We do not collect any data. The extension has no analytics, no telemetry, and no remote server it reports to.

3. Data We Read From the Page You Audit

To produce an audit, the extension's content script reads information that is already present in the public HTML of the active tab when you click "Run Audit." This includes:

Page metadata — title, meta description, canonical URL, robots/meta directives, viewport, charset, language
On-page content — headings, body text statistics, images and their attributes, links
Structured data — JSON-LD and microdata (e.g., Schema.org), Open Graph and Twitter Card tags
Technology signals — script sources, stylesheet links, and similar markers used to identify the technologies powering the page
Author and publish-date signals, where present in the page's markup

This reading happens entirely within your browser. None of it is sent anywhere — it is used only to compute the scores and checklists shown to you in the extension popup.

4. Where Your Data Is Stored

Storage location	What's stored	Persists after closing the popup?
Browser memory (in-page)	The current audit's results, while the popup is open	No — cleared when the popup closes
Your device's downloads folder	JSON/CSV export files, only if you click "Export"	Yes — same as any file you download
Remote servers	Nothing	N/A — the extension does not have one

The extension does not use chrome.storage, cookies, or any other persistent storage mechanism to retain audit data between sessions. Each time you click "Run Audit," the page is re-analyzed fresh.

5. Network Requests

The extension makes no network requests to any third-party server, analytics provider, or backend of ours. The one exception is a feature you must explicitly trigger yourself:

"Check Status" (Links section): if you click this button, the extension sends standard HTTP requests directly from your browser to same-origin links found on the page you're auditing (i.e., links pointing back to the same website), purely to check whether they return a valid response. Cross-origin (third-party) links are never checked this way — they are simply labeled as not checked. No results from this feature are sent to us or to any third party; they're displayed only in your popup.

6. Permissions This Extension Requests, and Why

Permission	Why it's needed
`activeTab`	So the extension can read the page you're currently viewing, only when you invoke it
`scripting`	To inject the content script that reads page metadata, into the active tab
`tabs`	To identify the active tab and its URL so the audit applies to the right page
Host permissions (`http:///`, `https:///`)	So the extension can run on any website you choose to audit; it does not act on a site until you click "Run Audit" there

7. Data Sharing

We do not share, sell, rent, or transfer any data to third parties, because we do not collect any data to begin with.

8. Children's Privacy

This extension is a website-auditing developer/marketing tool and is not directed at children. It does not knowingly collect information from anyone.

9. Changes to This Policy

If this extension's data practices ever change, this policy will be updated accordingly and the "Last updated" date above will reflect the change.
