Measure Copilot Evidence Collector

About

Measure Copilot Evidence Collector lets you capture live analytics signals from any website you're auditing — then export that evidence to supercharge a Measure Copilot audit report.

What it collects (locally, never automatically transmitted):
• GA4 and GTM container IDs detected on the page
• dataLayer push events as they fire in real time
• Consent Mode v2 signal states (analytics_storage, ad_storage, ad_user_data, ad_personalization)
• CMP presence signals (OneTrust, Cookiebot, Didomi, iubenda, CookieYes)
• Key journey events: page_view, add_to_cart, begin_checkout, purchase, generate_lead

How to use:
1. Visit the website you want to audit
2. Click the extension icon to open the popup
3. Browse through key pages and complete a purchase or lead journey
4. Click "Export evidence" to download an evidence JSON file
5. Upload the file at measurecopilot.com/audit for a deeper, more accurate audit report

Privacy:
All evidence is stored only in your browser's local storage. Nothing is sent anywhere without your explicit action. The extension does not collect passwords, cookies, payment details, or browsing history.

Broad host permissions (http://* and https://*) are required because users audit any website, not a fixed domain list.
