How to change the cookie time?

The default cookie time is 30 days.

If you want to change/overwrite this, please folow the the steps below:

Before you initialize your UTMSimple snippet, define handl_cookie_duration global variable to define your own cookie time.

<script>
    handl_js_license = "<your license key>"
    handl_custom_params = []
    handl_cookie_duration = 365
    var handl_js = document.createElement('script');
    handl_js.setAttribute('src','https://js.utmgrabber.com/utm.js?license='+handl_js_license);
    document.head.appendChild(handl_js);
</script>

In this example, cookies will expire after 365 days later.
