When you use the Piwik JavaScript Tracker Piwik will by default track the following information:

  • User IP address (see also: IP anonymisation)
  • Optional User ID
  • Date and time of the request
  • Title of the page being viewed (Page Title)
  • URL of the page being viewed (Page URL)
  • URL of the page that was viewed prior to the current page (Referrer URL)
  • Screen resolution being used
  • Time in local user’s timezone
  • Files that were clicked and downloaded (Download)
  • Links to an outside domain that were clicked (Outlink)
  • Time it takes for pages to generated (Page speed)
  • Location of the user: country, region, city, approximate latitude and longitude (Geolocation)
  • Main Language of the browser being used (Accept-Language header)
  • User Agent of the browser being used (User-Agent header)

From the User-Agent, we use our Universal Device Detection library to detect the browser, operating system, device used (desktop, tablet, mobile, tv, cars, console, etc.), brand and model.
