The size of your actual visible browser window — different from your full screen resolution if your browser isn't maximized.

An optional signal your browser can send asking websites not to track your behavior — most browsers no longer enable this by default.

INCOGNITO_MODE<br>checking...<br>● VISIBLE

Whether your browser appears to be running in private or incognito mode, detected via storage quota and API availability differences.

PRIVACY_BROWSER<br>checking...<br>● VISIBLE

Whether your browser appears to be a privacy-focused browser (Brave, Firefox with resistFingerprinting, or Tor Browser) based on API behavior and user agent signals.

AD_BLOCKER<br>checking...<br>● VISIBLE

Whether an ad blocker or content filtering extension appears to be active, detected by attempting to load a resource commonly blocked by ad filters.

DEVICE_MEMORY<br>reading...<br>● VISIBLE

An approximate amount of RAM available on your device, as reported by the browser. Reported in rough buckets (0.25, 0.5, 1, 2, 4, 8 GB) rather than exact figures.

GPU_RENDERER<br>reading...<br>● VISIBLE

The graphics card (GPU) your device is using, as reported by the WebGL API. Websites can read this to identify your hardware profile.

COLOR_DEPTH<br>reading...<br>● VISIBLE

The number of bits used to represent the color of each pixel on your screen. Standard displays use 24-bit color; HDR displays may report 30-bit or higher.

Frequently asked questions<br>Why can websites see this data — and what do they actually do with it?

What is my IP address?<br>Your IP address is a numerical label assigned to your device by your internet provider that identifies it on the network. Every request your browser makes must include your IP address so the server knows where to send the response — it's a fundamental part of how the internet works. Websites use it for fraud detection, rate limiting, and regional content delivery.

Can a website tell what city I'm in?<br>Websites can make a rough geographic estimate of your location by looking up your IP address in a regional database — no GPS or permission required. Internet providers are assigned blocks of IP addresses for specific regions, so a site can cross-reference your IP to guess your city or country. This powers features like showing local currency, nearby stores, or language defaults.

Why does this show coordinates as well as a city name?<br>Both come from the same IP-based estimate and have the same accuracy — typically resolving to your internet provider's regional hub, not your exact address. Coordinates are shown separately because they're useful...
