Is Debugger for Google Analytics 4 (GA4) safe?
GA4 Debugger reads GTM dataLayer events on every visited page and displays them in a DevTools panel.
The extension injects a script into every page to monitor the Google Tag Manager dataLayer, capturing events such as ecommerce purchases, add-to-cart actions, user IDs, and custom dimensions. These events are relayed from the page context through a content script to the DevTools panel for developer inspection. No data is transmitted to external servers; all captured data stays within the browser's extension runtime.
