Privacy Policy — Schema Markup Checker

Overview

Schema Markup Checker is a Chrome extension that scans the structured data (JSON-LD and microdata) present on the webpage you are currently viewing. This policy explains what data the extension accesses and, just as importantly, what it does not do with it.

What the extension accesses

When you click the extension icon, it reads the HTML of the current tab to find:

• <script type="application/ld+json"> tags
• Elements using itemscope, itemtype, and itemprop microdata attributes

This is limited to publicly visible structured data already present in the page's source code.

What the extension does not do

• It does not collect, store, or transmit any data to any server.
• It does not use any analytics, tracking, or third-party services.
• It does not access your browsing history, personal files, passwords, or any data outside the current tab's HTML.
• It does not require an account, login, or any personal information.

Local processing only

All scanning and analysis happens entirely within your browser, in memory, for as long as the popup is open. Nothing is saved once you close the popup or navigate away from the page.

Third-party links

The "Rich results test" button opens Google's own Rich Results Test tool in a new tab, passing along the URL of the page you were viewing. This interaction is governed by Google's own privacy policy, not this extension's.

Changes to this policy

If this policy changes, the updated version will be posted at this same location with a revised "last updated" date.
