Independent Analytics outputs a small tracking script on each page of your site. When a visitor arrives on your site, the tracking script runs, collecting data about the visitor and the page they’re viewing. Once the page is finished loading, the script sends this data to your own site via the WordPress REST API, and the data is then saved in your database.
This offers superior privacy to third-party apps that transmit your data to their own servers. With Independent Analytics, your data is both created and saved entirely on your site.
