I do not want to add the tracking code to SharePoint’s core.js/init.js file, what can I do?

Simply add the JavaScript tracking code to a common page component of your choice, such as master page, toolbar, Web Part , footer, HTTP Module, etc. OR install the "CardioLog Analytics" SharePoint feature.
