This Extension supports legacy implementations. Please see our Privacy Manager for a more up-to-date and comprehensive solution.

Providing visitors with the ability to opt out of tracking is a requirement in some areas. Since some browsers may not support the DNT (Do Not Track) technology, Tealium offers this Extension as a secondary measure by providing users with the ability to opt out of tracking by Tealium-managed Tags.

Configuring the Extension

The Tracking Opt Out Extension's scope is automatically set to Pre Loader to provide the user with the option to opt out of tracking before the other Tags load.

To enable the Extension:

  1. Navigate to the Extensions tab and add the Tracking Opt Out Extension, located under the Privacy tab.


  2. Once the Extension is added, you will notice two HTML anchor links. Add these links to the site in which you offer visitors the ability to opt out of tracking. Remember that the Extension must be activated for these links to work.

This Extension only needs to be added once.


How it Works: Behind the Scenes

When a user chooses to opt out, Tealium sets a first-party cookie that will inform our service of this selection. That cookie is read immediately on the next page, and instructs our services not to execute the utag.js file or load any 3rd-party libraries. If the user chooses to opt in later, the cookie is reset with their new selection, and the utag.js file and 3rd-party libraries load as normal.

Note: If you are an existing customer whose account was created before January, 2012 and you wish to enable the Tracking Opt Out Extension, your current utag.js template needs to be updated. Please contact your Account Manger if you need assistance or guidance to update your template.
