What this tool shows
IP Address & Location
Your public IP, local IP via WebRTC, approximate location, ISP, and whether a VPN or proxy is detected.

Audio Fingerprint
Web Audio API can generate a unique signature from your device's audio processing characteristics.
Permissions & APIs
Do Not Track, cookies, geolocation, notifications, microphone, camera, screen sharing, network connection info, clipboard access, built-in PDF viewer, and other permissions and APIs available to websites.
Media Devices
Cameras, microphones, and speakers visible to the browser via the MediaDevices API.
Advanced APIs & Hardware Access
Powerful browser APIs like Web Bluetooth, Web USB, Web Serial, Web HID, Web NFC, File System Access, and Contact Picker that websites can potentially use.
Why this matters
Every website you visit receives a stream of data from your browser — often without you realising. Your IP address reveals your approximate location and internet provider. Your browser fingerprint combines screen size, installed fonts, timezone, and hardware details into a profile that can track you across sites, even without cookies.
WebRTC can expose your local network IP address behind a VPN. Advanced APIs like Web Bluetooth, Web USB, and File System Access give websites potential access to hardware and files — though most require explicit permission. This tool simply shows you what is technically possible so you understand your exposure.
