How do we use cookies?

When using Smartlook services and products, temporary files, called "cookies", can be stored, which may contain information capable of identifying the user. No personal data will be stored in the cookies.

SL_C_23361dd035530_KEY - this is the project key, specific to each project that you add to your Smartlook dashboard

SL_C_23361dd035530_SID - this is the session ID, that is assigned to each new session that is being recorded

SL_C_23361dd035530_VID - this is the visitor ID, assigned to each new visitor.

The cookies can be deleted manually by clearing the browser's cache

  • Cookies will be saved for 13 months

- The script can also be used without cookies, basically having the code to look like this

<script type='text/javascript'>
window.smartlook||(function(d) {
var o=smartlook=function(){ o.api.push(arguments)},h=d.getElementsByTagName('head')[0];
var c=d.createElement('script');o.api=new Array();c.async=true;c.type='text/javascript';
smartlook('init', 'SMARTLOOK PROJECT KEY', { "cookies": false });

What are cookies used for and why we store them?

The use of cookies helps with the association of sessions to users (User ID).

For example, if you have a domain that includes and, and you record it in the same project, then visitors to the website and each specific session will be shared. When you replay the session you can see how user switched, between and tabs.

NOTE: This information will only be shared when both pages are recorded within the same project and share the main domain name ( This cross tracking can only be achieved with cookies enabled. If you disable cookies, then you’ll lose this feature, and the visitor journey will be separated into 2 different sessions.
