Open Settings → Chat & Order Button → Statistics for the last 7, 30 or 90 days: total clicks, clicks per button, a daily chart, clicks per agent and device, and the pages and products with the most clicks.
Only the button, agent, page and device type are stored. No IP addresses, no cookies. Records older than 12 months are deleted automatically. Your own clicks are not counted while you are logged in as an administrator, unless you turn that option off.
