Disabling cookies in Google Analytics - gtag.js

Question

I am looking for a way to disable the cookies set by Google Analytics. I found some infos in Google's devguides: https://developers.google.com/analytics/devguides/collection/analyticsjs/cookies-user-id#disabling_cookies

Here it says that I should add the following code:

ga('create', 'UA-XXXXXXXXX-X', {
  'storage': 'none'
});

But where exactly? I already tried to add it inside the tracking code:

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

  gtag('config', 'UA-XXXXXXXXX-X');


  ga('create', 'UA-XXXXXXXXX-X', {
  'storage': 'none'
});
</script>

I'm grateful for every clue.

gtag('consent', 'default', {
    'ad_storage': 'denied',
    'analytics_storage': 'denied'
});

Note that it must be called before any other commands that send measurement data.

Very important that consent is executed before config.

The guidance has consent line above js: developers.google.com/tag-platform/devguides/consent/…

storage: 'none' is for analytics.js https://developers.google.com/analytics/devguides/collection/analyticsjs/cookies-user-id#disabling_cookies

For gtag.js, I think client_storage: 'none' is what you're looking for. It's referenced in a Medium article titled How to use Google Tag Manager and Google Analytics Without Cookies

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

  gtag('config', 'GA_MEASUREMENT_ID', {
       client_storage: 'none',
       client_id: CLIENT_ID,
  });

</script>

This is a good answer, but it omits mention of an important problem; creating that CLIENT_ID as the link in the answer describes..

Two things, you have confused two versions, the ga create and gtag are different versions. Use the gtag one. Your code for this to work is below:

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

 window['ga-disable-UA-XXXXXXXXX-X'] = true;

 gtag('config', 'UA-XXXXXXXXX-X');

});
</script>

See reference here https://developers.google.com/analytics/devguides/collection/gtagjs/user-opt-out

This disables Analytics entirely, though. How do you enable Analytics, but not have it set a cookie? (Equivalent to ga's "storage:none")

Jesse Over a year ago

I believe the below is what you are after. ‘gtag('config', '<TARGET_ID>', { cookie_expires: 0 });’ If you set the cookie_expires value to 0 (zero) seconds, the cookie turns into a session-based cookie and expires once the current browser session ends.

M Somerville Over a year ago

Thanks for the reply, but that still sets a cookie (which given browser session time nowadays could actually be longer than a timed-expire cookie); I would like a way that doesn't set a cookie at all (which you can do easily with "ga"). Doesn't look like there is a way.
