Device Identification
This page is designed to show what technical signals websites on the internet can read about your device. The goal is to make these accessible browser signals understandable.
Why is this approximate?
Hardware identifiers like your CPU or RAM cannot be easily masked because the browser reads them directly from the device to run web applications efficiently. The best way to reduce exposure is keeping your software updated and using privacy-focused browsers.

Frequently Asked Questions
Can websites see my exact hardware model?
No. Browsers only expose generic details (like CPU logical core count, approximate RAM buckets, and GPU vendor). Exact serial numbers and motherboard models remain hidden.
Why does my RAM show as 8GB when I have 16GB or 12GB?
Modern browsers intentionally round memory values into predefined buckets (2, 4, 8 GB) to protect your privacy and prevent hardware profiling.
How do permissions affect my device privacy?
Camera, microphone, and location permissions require explicit consent. You can revoke them anytime in your browser site settings.
