For some privacy laws, anonymized statistics, and a specific configuration of your analytics provider, e.g., Google Analytics, allow setting statistics cookies before consent. 

How to configure your Google Analytics account for GDPR and other privacy laws can be found here. Anonymizing your IP addresses for Analytics with Tag Manager is easy. Even easier, is letting Complianz anonymize IP addresses, but how do you know they are anonymized?

How anonymizing IP addresses works

A user visits a website with an IP address, which might look like:

  • 12.214.31.144 or if IPV6 is allowed:
  • 2001:0620:0000:0000:0211:24FF:FE80:C12C

Before Google Analytics collects the IP addresses and writes to your Google Dashboard it will go through a script which can look like the below snippets, an based on your implementation.

  1.  gtag(‘config’, ‘GA_TRACKING_ID’, { ‘anonymize_ip’: true });
  2. ga(‘set’, ‘anonymizeIp’, true);

This function will strip a significant part of your IP address so, in the eye of privacy laws, changes from personal data, to non-identifiable data.

It does so by changing (example)

  • 12.214.31.144 or if IPV6 is allowed:
  • 2001:0620:0000:0000:0211:24FF:FE80:C12C

to

  • 12.214.31.0 or if IPV6 is allowed:
  • 2001:0620::::::FE80

But you can’t check if these IP addresses are anonymized correctly in real-time. That’s why Google added a parameter in the URL they use to collect information and write to your Google Analytics dashboard, which you identified with a UA-Code.

Confirm your anonymizing IP Addresses

We will use demo.complianz.io so you can check and compare if needed.

You will need to open your browser console, for Chome, this is a right-mouse click -> inspect or CMD/CTRL+Shift+I

You will need to find aip=1 as a query string parameter, to do this:

  1. Open the tab Network
  2. Open the tab Headers
  3. Scroll down to Query Strings Parameters
  4. Find the parameter AIP=
  5. If it has a one 1, your IP is anonymized!

 

 

If your API = 0, please have a look at the above snippets and compare them with the page source of your website. Open the page source with right-mouse click -> Page source or CMD/CTRL + U.
