Disable Google Analytics

In some cases, it may be necessary to disable Google Analytics on a page without removing the gtag.js tag. For example, you might do this if your site's privacy policy provides an option for the user to opt-out of Google Analytics.

The gtag.js library includes a window property that, when set to true, disables gtag.js from sending data to Google Analytics. When Google Analytics attempts to set a cookie or send data back to the Google Analytics servers, it will first check if this property is set, and will take no action if the value is set to true.

To disable Google Analytics programmatically, set window['ga-disable-MEASUREMENT_ID'] to true. Replace MEASUREMENT_ID with a valid Google Analytics measurement ID:

<!-- Global site tag (gtag.js) - Google Analytics -->
<script async src="https://www.googletagmanager.com/gtag/js?id=MEASUREMENT_ID"></script>
  window['ga-disable-MEASUREMENT_ID'] = true;
  window.dataLayer = window.dataLayer || [];
  function gtag(){dataLayer.push(arguments);}
  gtag('js', new Date());

  gtag('config', 'MEASUREMENT_ID');
