Frequently Asked Questions
What information is contained within a browser User-Agent string?
A User-Agent header reveals the browser name, layout rendering engine (such as Blink or Gecko), operating system platform, and CPU architecture.
Why do modern browsers freeze or reduce user-agent details?
Major browser vendors (Chrome, Safari, Firefox) reduce user-agent specificity to reduce browser fingerprinting surface area and protect visitor privacy.
Is my device hardware data sent across the web?
No. Screen resolution, pixel ratio, and client properties are read directly from the DOM window and navigator APIs in your local browser.
