Frequently Asked Questions
How does the tool know my browser?
Your browser tells every website its name and version in a text called the user agent. Newer browsers also share details through a feature called Client Hints.
Is any of my data stored?
No. The details are read inside your browser and are not sent to us.
Why does it show Chrome when I use another browser?
Many browsers are built on Chrome and share its engine. The tool looks for their own names, but a few privacy browsers hide them.
How do I update my browser?
Open the browser menu, go to Help or About and it will check for updates. Keeping it current is important for security.
Why is my screen size different from my window size?
The screen is your whole display. The window is only the visible area of the page inside the browser.
Can I change my user agent?
Yes, with developer tools or an extension. Then this tool shows the changed value.
