When you use the Matomo (Piwik) JavaScript Tracker Matomo 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)
• Pages generation time (the time it takes for webpages to be generated by the webserver and then downloaded by the user: 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.
