Is there a setting on Google Analytics to suppress use of cookies for users who have not yet given consent

Question

According to EU Article 5(3) of the E-Privacy Directive (a.k.a 'The Cookie Laws'), web sites that target EU users have to gain opt-in consent from users before they set a cookie.

See ICO Guidance

I am trying to square this with Google Analytics on my web site.

I would imagine that Google Analytics (GA) can do a certain level of analytic data gathering without requiring the use of cookies.

However, I cannot find any info on this (on the Google sites/settings panels) about how to relay information about the 'state of consent' back to Google during a page request. So, my only option seems to be that I should not embed Google tag code at all if the user has not explicitly given consent. Which seems a bit drastic.

Letting my serverside script set a hasConsentedToCookies=FALSE flag in the JavaScript tags would allow me to instruct Google's services to run in a gracefully degraded fashion.

Is there a setting on Google Analytics to suppress use of cookies for users that have not yet given consent?

If so, where can I find info on this?

Answer 1

EDIT (2019): The below answer predates GDPR and likely requires revision.

Google Analytics has a new set of APIs to assist with compliance with a cookie opt-out. Here's the documentation, and here's their help docs.

There has been some ambiguity as to whether the EU Cookie Regulations (as implemented in member countries) require that passive web analytics tracking requires opt-in mechanisms for compliance. If you're concerned one way or another, consult an attorney. Google is empowering you to make the decision as to how you want to proceed.

They'll leave implementation details to you, but, the idea is, once you've determined whether or not to track the user in Google Analytics, if the answer is to not track, you'd set the following property to true before Google Analytics runs:

window['ga-disable-UA-XXXXXX-Y'] = true;

Where UA-XXXXXX-Y is your account ID in Google Analytics

As the other posters have noted, Google Analytics relies on cookies. So, you're not able to do any kind of tracking without cookies. If you've determined that someone is not to be cookied for tracking, you'll need to implement something like this:

if(doNotCookie()){
   window['ga-disable-UA-XXXXXX-Y'] = true;
}

Opt In

This does require a little bit of jujitsu for when you first load Google Analytics, since this property will need to be set before Google Analytics runs to prevent tracking from ever happening, which means, for an "opt in to tracking" approach, you'd probably need to implement a mechanism where, on first visit, Google Analytics is automatically disabled in the absence of an opt-in cookie (cookies that determine cookie preferences are explicitly allowed), and then, if an opt-in happens, re-runs Google Analytics. On subsequent pageviews, all would run smoothly.

Could look something like (pseudo-code):

if( hasOptedOut() || hasNotExpressedCookiePreferenceYet() ){ //functions you've defined elsewhere
     window['ga-disable-UA-XXXXXX-Y'] = true;
}
  var _gaq = _gaq || [];
  _gaq.push(['_setAccount', 'UA-XXXXXXX-Y']);
  _gaq.push(['_trackPageview']);


  function onOptIn(){ //have this run when/if they opt-in.
      window['ga-disable-UA-XXXXXX-Y'] = false;
      //...snip...
      //set a cookie to express that the user has opted-in to tracking, for future pageviews
      _gaq.push(['_trackPageview']); // now run the pageview that you 'missed'
   }

Opt Out

With this approach, you'd allow the user to opt-out of tracking, which would mean you'd use a cookie to set the ga-disable-UA-XXXXXX-Y' property and a cookie to manage it in the future:

if( hasOptedOut() ){ // function you've defined elsewhere 
     window['ga-disable-UA-XXXXXX-Y'] = true;
}

  var _gaq = _gaq || [];
  _gaq.push(['_setAccount', 'UA-XXXXXX-Y']);
  _gaq.push(['_trackPageview']);

Answer 2

You can disable the use of cookies for Google Analytics by specifying the {'storage' : 'none'} option when creating the tracker instance.

See Google's guide on the subject for more details.

Answer 3

I often never ask users to opt out for google analytics, that is because i never set cookies and i never save their ip (and other personal data).

(function(i,s,o,g,r,a,m){i['GoogleAnalyticsObject']=r;i[r]=i[r]||function(){
(i[r].q=i[r].q||[]).push(arguments)},i[r].l=1*new Date();a=s.createElement(o),
m=s.getElementsByTagName(o)[0];a.async=1;a.src=g;m.parentNode.insertBefore(a,m)
})(window,document,'script','//www.google-analytics.com/analytics.js','ga');

ga('create', 'UA-98765432-1', 'www.example.com', {
  'anonymizeIp': true
  , 'storage': 'none'
  , 'clientId': window.localStorage.getItem('ga_clientId')
});
ga(function(tracker) {
  window.localStorage.setItem('ga_clientId', tracker.get('clientId'));
});
ga('send', 'pageview');

Also check out this code at Convert Google Analytics cookies to Local/Session Storage

This script will not set any cookies, but still track via google analytics. This will actually have the same effect on privacy as using cookies, because google still records the users IP-address.

That is where the anonymizeIp switch comes in. This tells google to only save an anonymized version of the IP-address. An anonymized IP-address is not considered personal data, so the users privacy will be respected.

AFAIK cookie law is all about privacy and does allow website to track their usage. I am not a lawyer or anything but in my opinion this script complies to the EU cookie law.

Answer 4

As a quick note, the BBC (probably the most popular site in the UK) has taken an interesting approach to complying with cookies - they've displayed a banner to users telling them that cookies are set and provide a couple of links.

This one explains what cookies are. This one lets them manage their cookies, but most interestingly of all they supply a link to Google Analytics to allow users to opt-out of GA in its entirety. So, in summary, the BBC have taken the view that they can tell the user what cookies are set and then provide a link to Google to allow the user to opt out of all GA cookies. For me, that's a lot less hassle than you telling GA to opt-out for an address through JS.

Answer 5

Latest Google Analytics (gtag.js) has a "Consent mode" just for that (still in beta):

https://developers.google.com/gtagjs/devguide/consent

It looks like this:

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

Then you can update these settings at a later time in the case the user consents.

Answer 6

You can disable google analytics cookies by adding this code at the top of google analytics code (before line: var _gaq = _gaq || [];):

ga('create', 'UA-XXXXXX-XX', {'storage': 'none'});
ga(function(tracker) {
  var clientId = tracker.get('clientId');
});

However some features of google analytics (for example real time stats) do not work properly after this modification. More about google analytics cookies: https://developers.google.com/analytics/devguides/collection/analyticsjs/domains?hl=en#disableCookies

Answer 7

I was facing the same problem.

Eventually, I got a solution in the line of Elmer's reply but playing safe regarding IPs, that is without using localStorage

// Create a fake ID instead of storing anything locally
function guidGenerator() {
    var S4 = function() {
       return (((1+Math.random())*0x10000)|0).toString(16).substring(1);
    };
    return (S4()+S4()+"-"+S4()+"-"+S4()+"-"+S4()+"-"+S4()+S4()+S4());
}

...
ga('create', 'UA-XXXXXX-Y', {
        'storage': 'none',
        'clientId': guidGenerator()
});

(-) Every page visited will count as a new visitor in Google Analytics, so I am losing quite a lot of functionalities there.

(+) But I can live with it and I believe I am safe regarding data privacy legislations.

Any feedback or improvement suggestion is more than welcome.

Answer 8

Common way to handle this so far is the method used by wolf-software's jquery plugin whereby it prevents the script from running until the user opts in. The ICO updated their guidelines last week, however, to say that it is acceptable to rely on 'implied consent' of the sort used on the BBC site. While I don't really think that's within the spirit of the law, it's what's deemed acceptable by those enforcing it. Given that most of the EU has yet to implement the directive, I'd say it's highly likely they'll follow the UK's lead.

There's an interesting article about the UK updates here:

http://www.redant.com/articles/eu-cookie-law-update-ico-adopts-softly-softly-approach/

Answer 9

EDIT: There is a Google Analytics setting for this with the Asynchronous GA snippet.

There isn't a Google Analytics setting for this, as you're suggesting, you would need to conditionally exclude the script for those that have not consented if you want to use the Google Analytics Javascript tracking script.

There are some solutions out there already that can be helpful instead of rolling your own. Javascript: http://cookies.dev.wolf-software.com/demo/index.htm

Here is a solution that allows using Google Analytics basic features without cookies, by doing the tracking server side, this example is in PHP: http://techpad.co.uk/content.php?sid=205

Answer 10

For a less intrusive UX solution you can set implied consent for google analytical cookies by placing a link to: cookiestatement.eu (no javascript, no popups, no ads)

Answer 11

Sorry for being late to answer but I was looking for the same thing recently until I found out a way myself. It may not be the right way to do it but it works. (only works on site in question does not opt-out of GA completely). I have tested for a few days to make sure.

The way I have managed to do it is using a PHP cookie. First start off with adding the analyticstracking.php include...

<?php include_once('analyticstracking.php'); ?>

and in analyticstracking.php add the following...

<?php
if($_COOKIE['consent_cookie']=="Y"){
?>

<script type="text/javascript">
var _gaq = _gaq || [];
  _gaq.push(['_setAccount', 'UA-********-*']);
  _gaq.push(['_trackPageview']);

  (function() {
    var ga = document.createElement('script'); ga.type = 'text/javascript';     ga.async = true;
    ga.src = ('https:' == document.location.protocol ? 'https://ssl' :      'http://www') + '.google-analytics.com/ga.js';
    var s = document.getElementsByTagName('script')[0];      s.parentNode.insertBefore(ga, s);
  })();
</script>

<?php   
}
else{
//do nothing
}
?>

Before the user has consented to cookies Google Analytics won't work and once they have, the 'consent_cookie' will be saved and will allow GA to work but if the 'google' cookie is destroyed it will stop GA from working (Obviously).

Like I said it may not be the right way but I have tried and tested and it does. Hope this helps somebody.

Answer 12

There's a few steps to do in order to make GA work only after user accepts the cookie usage.

Disable cookies

   <script async src="https://www.googletagmanager.com/gtag/js?id=UA-XXXXXX-Y"></script>
-- <script>
-- window.dataLayer = window.dataLayer || [];
-- function gtag(){dataLayer.push(arguments);}
-- gtag('js', new Date());
-- gtag('config', 'UA-XXXXXX-Y');
-- </script>

At the point where GA is implemented, this needs to be updated by just importing the gtag.js script and removing the GA initialisation.

Enable GTag when user accepts cookies

GTag Opt In is a tool that enable and disable GA when user accepts/rejects cookies.

<script src="https://www.npmcdn.com/[email protected]/dist/index.js"></script>
<script>
  GTagOptIn.register('UA-XXXXXX-Y');

  ...
  // On user opt in
  GTagOptIn.optIn();
  // On user opt out
  GTagOptIn.optOut();
  ...
</script>

Library is loaded. GA tracking ID is registered. Later the optIn and optOut functions can bind to user actions' accept/reject.

You can read more about it on How To Implement Google Analytics With Opt In.

Answer 13

You can use something like Legal Monster - to block cookies if user didn't give consent for analytical cookies.

legal.js currently supports blocking (and enabling) of analytics and marketing cookies; more categories will be available in the future.

Here is more detailed guide on blocking cookies.

Answer 14

Update 2022: Its not about Cookies anymore. Now you need a consent even for loading google fonts from outside the EU. This is because doing so the users IP (very private Information haha) will be send to the USA. Im not a lawyer but this affects Adsense and Analytics as well. Here you will find a solution how to load Adsense and Analytics only if consent is given: https://stackoverflow.com/questions/70967060/loading-google-adsense-analytics-and-youtube-only-when-consent-is-given

Simply call setTimeout("analyticsladen()", 1); when consent is given:

The new Google Analytics 4 Code is:

 <script>
 window.dataLayer = window.dataLayer || [];
 function gtag(){dataLayer.push(arguments);}
 gtag('js', new Date());

 gtag('config', 'G-####');
 </script>


 <script type="text/javascript">
 function analyticsladen() {
 var script = document.createElement('script');
 script.type = 'text/javascript';
 script.src = 'https://www.googletagmanager.com/gtag/js?id=G-####';
 document.body.appendChild(script);
 }
 //setTimeout("analyticsladen()", 1);
 </script>

Or you can use the old Google Universal Analytics Code. It will only work till June 2023 (says google):

 <script type="text/javascript">
 var _gaq = _gaq || [];
 _gaq.push(['_setAccount', 'UA-####-#']);
 _gaq.push (['_gat._anonymizeIp']);
 _gaq.push(['_trackPageview']);

 var analyticsladen = function(){
 var ga = document.createElement('script');
   ga.type = 'text/javascript';
   ga.async = true;
   ga.src = ('https:' == document.location.protocol ? 'https://ssl' : 'http://www') + '.google-analytics.com/ga.js';

   var s = document.getElementsByTagName('script')[0];
   s.parentNode.insertBefore(ga, s);
   }

 </script>

Funfact: Google ranks my page 4 steps higher scince im not using analytics at all anymore :D
