Each data point below is collected silently by websites you visit. Together they create a fingerprint that can identify you across sites without any cookies or login.
—
The raw string your browser sends to every website. Identifies your browser, rendering engine, and OS without consent.
—
Parsed from your user agent. Browser name and version combined with OS narrows your identity significantly.
—
Screen dimensions reveal display hardware and device class. Combined with pixel ratio, it is highly distinctive. Screen resolution spoofing cannot be detected — extensions that spoof this value are indistinguishable from a genuine screen at that resolution.
—
Your local timezone reveals your geographic region even when your IP is masked by a VPN or proxy.
—
Browser language settings reveal your locale and preferred language, often correlating with geographic location.
—
This header signals you don't want to be tracked. Most advertising networks ignore it — it has no legal enforcement.
—
Knowing cookies are enabled allows sites to set persistent tracking identifiers on your device.
—
JavaScript enables nearly all modern fingerprinting. If you're reading this, it is active in your browser.
—
Your GPU and graphics drivers render graphics slightly differently than others. This hash represents your unique rendering signature.
—
WebGL exposes your GPU model and driver version — one of the most stable cross-session fingerprinting vectors.
—
Font presence is detected via canvas width measurement. Your font set is shaped by your OS, region, and installed software.
—
Reveals whether you're on a touch device. Combined with screen resolution, it identifies device class and form factor.
—
navigator.hardwareConcurrency exposes your logical CPU core count. Combined with GPU and memory, it profiles your hardware tier.
—
navigator.deviceMemory reports approximate RAM in GB. Intentionally imprecise, but still useful for fingerprinting device class.
—
The Network Information API exposes your effective connection type (4G, 3G, etc.). Not available in all browsers.
