A flag indicating whether your browser is configured to store small text files that websites can write and read back later.

DO_NOT_TRACK<br>reading...<br>● VISIBLE

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

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 for a specific case: checking whether a VPN or proxy is successfully changing your apparent location. If you're connected to a VPN and these coordinates still match your real area, the VPN may not be masking your location correctly.

Can websites see what browser I'm using?<br>Yes. Browsers automatically send their name and version in something called the User-Agent header with every page request. Developers use this to test compatibility, serve the right code for older browsers, and understand which platforms their audience uses.

Do websites know if I'm using Windows or Mac?<br>Yes. Your operating system — Windows, macOS, Android, iOS, Linux, etc. — is included in the same User-Agent string as your browser, sent automatically with every request. Developers use it to ensure their site looks and works correctly across different platforms, and analytics tools use it to track broad device trends.

Can websites tell what type of device I'm using?<br>Yes. Your browser's user agent string includes signals that let websites infer whether you're on a desktop, tablet, or mobile phone. Web developers use this to serve device-appropriate layouts and features — for example, serving a touch-optimized interface to mobile visitors, or disabling certain animations on lower-powered devices.

Can websites see how many CPU cores my device has?<br>Yes. Browsers expose the number of logical processor cores through the navigator.hardwareConcurrency property,...
