We do use Google Analytics to collect information about site usage. That information is anonymous so we cannot track individual users (not that we would if it were possible).
We look at the collective data collected to see which browsers, operating systems are being used. We also look at the summary of browser language settings and country locations. We then use that data to help guide decisions about how the site can be developed and improved.
The following are typical examples of the data collected.
Aggregated browser usage for the major browsers.
For Windows users (80% of users), the version of Windows client operating system. Unfortunately, at the moment the data doesn't distinguish between Windows 10 and Windows 11.
The user language based on the browser language setting.
The user language based on the country location.
The user location based on their ISP connection to the Internet.
