Common questions
Does DROP save this result?
No. The site has no application database or account system. This tool does not persist its result.
Can the result change?
Yes. Browser privacy settings, permissions, connected hardware and window size can affect what is available.
What does this result mean?
Check your operating system from browser-provided information. No result storage. Browser-reported values can change when you resize a window, connect another display, change permissions, or update system settings. This page shows the current result without creating an account or saving a history.
How is it measured?
The result comes from standard browser APIs available on this device. Detection is deliberately conservative: when a detail cannot be identified reliably, the tool reports it as unknown instead of inventing a hardware specification.
