Your device type, CPU cores, available RAM, touch support, and hardware capabilities — detected instantly from your browser without sending any data to our servers.
Modern web browsers expose a range of hardware and device information through JavaScript APIs. This information is used by websites to optimise content delivery, detect device capabilities, and provide tailored experiences. The key device properties detectable via browser APIs include: CPU logical core count (via navigator.hardwareConcurrency), approximate device memory in GB (via navigator.deviceMemory), touch screen support and maximum touch points (via navigator.maxTouchPoints), the platform string (via navigator.platform), and GPU renderer information (via the WebGL API).
The combination of device hardware information, browser details, screen resolution, and timezone creates a highly unique "fingerprint" that can be used to identify you across websites even without cookies. This technique is known as browser fingerprinting.
Browser fingerprinting is a tracking technique that collects various browser and device attributes — such as your user agent, screen resolution, installed fonts, CPU cores, GPU renderer, and timezone — and combines them into a unique identifier. Unlike cookies, fingerprinting does not require any data to be stored on your device.
Studies suggest that browser fingerprints can be unique to 1 in 286,777 browsers, making them an effective tracking tool. Privacy-focused browsers like Firefox, Brave, and Tor Browser include anti-fingerprinting measures to reduce the uniqueness of your fingerprint.
