How We Detect Your Device - Technical Methodology
We believe in transparency. Here's exactly how we detect each piece of information and how accurate it is.
IP Address
Fetch from ip-api.com
Your public IP is fetched from a geolocation API. This is your real IP address as seen by websites.
Browser & Version
navigator.userAgent
Parsed from the User-Agent string. Accurate for identifying browser name and version.
Operating System
navigator.platform + userAgent
Detected from platform info and User-Agent. Generally accurate for major OS detection.
WebRTC Leak Status
RTCPeerConnection
We create a WebRTC connection to detect if your real IP is exposed, even through VPNs.
Device Memory
navigator.deviceMemory
Returns bucket values (2, 4, 8, 16 GB) for privacy. NOT your exact RAM. 12GB RAM shows as 8GB.
Storage Quota
navigator.storage.estimate()
Shows the maximum storage the browser can theoretically use. NOT your actual disk space or SSD capacity.
Connection Type
navigator.connection.effectiveType
A heuristic guess (2g/3g/4g). WiFi and Ethernet both show as '4g' if fast. Not your actual network type.
GPU Information
WebGLRenderingContext.getParameter()
GPU info from WebGL. May show ANGLE translation layer (e.g., 'ANGLE Metal Renderer') instead of exact GPU model.
CPU Cores
navigator.hardwareConcurrency
Returns logical cores (threads). Cannot distinguish performance vs efficiency cores on Apple Silicon.
Why These Limitations?
Browsers intentionally hide exact hardware details for privacy and security. This prevents websites from uniquely identifying you based on hardware. We show what the browser allows us to see - nothing more, nothing less.
