Tracking Script & Data Collection

General Information

The Tracking Script is hosted on a CDN provided by Apsis, which means it's a third-party script. The requirements for the Tracking Script to properly perform are:

  • JavaScript.
  • LocalStorage.
  • Cookies.
  • Internet connection.




Here's a sample of a typical APSIS One Tracking Script:

<script type='text/javascript'>

(function (d) {

var apc = d.createElement('script'), fs;\n apc.type =


apc.charset = 'UTF-8';

apc.async = true;

apc.src = '


fs = d.getElementsByTagName('script')[0];

fs.parentNode.insertBefore(apc, fs);





Tracked Data

The web data collected is stored in 2 places: in visitors’ browsers and in APSIS One’s cloud.

All data is stored as long as the APSIS One account admin has activated all options available in all Website tool activities in APSIS One, and that the visitor has given cookie consent. All events are stored with a timestamp.

Here’s all data collected according to activity:


Signup bar

  • A value is submitted (email address, phone number).
  • Click on return offer (CTA that appears after visitor has already sent value).

All above events include:

  • A unique activity ID for the signup bar. A website may have more than one active signup bar.
  • The web domain the signup bar is active on.
  • The URL where the signup bar is displayed on.
  • Referrer page: the webpage the visitor came from, before arriving to the page where the signup bar is displayed.
