Anonymizer power-up

  • Updated


Its main goal is removing or anonymizing user data from Google Analytics 4 & Universal Analytics.



After Anonymizer is configured, you should update tagging server URL for your Google Analytics to the one that ends with /anonymize. For example, if the default tagging server URL is, then URL with Anonimiser will look like


When GA requests go through the tagging server URL that includes /anonymize, we automatically remove or anonymize selected parameters. 



You will have two options for most parameters: leave as is or remove. For two parameters (IP and Client ID), you will see options to Anonymize and Anonymize Strictly. 



Anonymize - removes the last octet.

Anonymize Strictly - removes the last two octets


Client ID. Works only if you use JavaScript Managed client identification.

Anonymize - use a hash of IP+UserAgent and add year+month.

Anonymize Strictly - use a hash of IP+UserAgent and add a timestamp, crc32_hash(IP+UA).timestamp
