PageSpeed & Core Web Vitals Checker by RunLocal Marketing. Last updated: November 2026.
When you click the extension icon or choose "Test this page/link's speed", the extension reads the URL of that page. It does not read page content, browsing history, cookies or form data.
The URL you test is sent to the Google PageSpeed Insights API (Google Privacy Policy). It is never sent to RunLocal Marketing's servers.
Test results, score history and your settings (including an optional API key) are stored locally in your browser with chrome.storage.local. You can delete them at any time from the extension's Settings page or by removing the extension.
Links from the extension to runlocalmarketing.com include UTM campaign parameters so we can see which features are used. No personal identifiers are attached.
The use of information received from Google APIs adheres to the Chrome Web Store User Data Policy, including the Limited Use requirements. We do not sell or transfer user data to third parties.
