Frequently Asked Questions
What is a user agent?
A string that browsers send to identify themselves. It includes browser name, version, operating system, and device type.
Why are user agents so complex?

Is my user agent private?
Yes, all parsing happens locally. However, note that your user agent is sent to every website you visit.
