Opt-out for intelligent tracking

When using Intelligent Tracking, no cookies are set on the visitor browser.

The standard Client Managed opt-out code described in 7.2 Implementing Opt-Out with IBM Digital Analytics First Party Data Collection Solutions cannot be used to implement visitor opt-out for Intelligent Tracking. To provide visitors the opportunity to opt-out of Intelligent Tracking, the cmSetOptOut function is provided. This function must be called on each and every page of the web site with the designated value ("A", "Y" or "N").

The opt-out form or other input mechanism used by visitors to make the opt-out, opt-anonymous or opt-in decision must be provided by the web site author: this input code is not provided by IBM®. The visitor decision should be persisted by the web site author so that the cmSetOptOut(...) function can be called with appropriate parameter value from each new page.

Available parameter values for the cmSetOptOut function:
Parameter value Setting

A Anonymous data collection

Y Total opt-out of all data collection

N No opt-out. Normal data collection

Parameter value	Setting
A	Anonymous data collection
Y	Total opt-out of all data collection
N	No opt-out. Normal data collection

Script block example:

<script type="text/javascript">
cmSetOptOut("Y");   // total visitor opt-out of data collection on this page
</script>
