7.2.5 Implementation - Opt-Out for Client Managed First Party

To provide opt-out functionality for visitors to a client-managed first party implementation, provide an Opt-Out form or other HTML that allows visitors to select their opt-out preferences.

The opt-out HTML should call the function SetOptOut(value) with one of three possible parameter values:

empty ("") for opting-in to full data collection;
"opt_out" for complete opt-out of data collection;
"anonymous" for opting-in to anonymous data collection.

Opt-Out HTML Example

The HTML code below provides an example opt-out page submitting the SetOptOut function in response to visitor choice. Modify this HTML to incorporate seamlessly into your website with appropriate language, navigation, formatting and images.

<HTML>
<HEAD>
<TITLE> Opt Out Page Example </TITLE>
<script type="text/javascript" src="//libs.coremetrics.com/eluminate.js"></script>
<script type="text/javascript"> 
// send data to production - Client-Managed 1st Party
cmSetClientID("99999999",true,"data.coremetrics.com","thesite.com");
</script>
</HEAD>
<BODY>
<script type="text/javascript">
var currentStatus = cI("CMOptout");

if (!currentStatus) {
	currentStatus = "opt-in";
}
function setOptOut(value) {
	var futureDate = new Date();
	futureDate.setFullYear(futureDate.getFullYear() + 20);
	document.cookie = "CMOptout=" + value + "; path=/;" + ";
 expires=" + futureDate.toGMTString();
// example of setting cookie domain to 2nd level so opt-out is effective for 
       .thesite.com and all subdomains.
// document.cookie = "CMOptout=" + value "; path=/; domain=.thesite.com" + "; 
       expires=" + futureDate.toGMTString();
	currentStatus = cI("CMOptout");
	if (!currentStatus) {
		currentStatus = "opt-in";
	}
}
