Frequently Asked Questions
What is a User Agent?
A User Agent (UA) is a text string that your web browser sends to websites to identify itself, the operating system, and rendering engine.
Is my User Agent string secure?
Yes! The parsing is performed locally in your browser using the ua-parser-js library. No user agent data is sent to our servers.
