📝 What Can a Website See About Your Computer
August 13, 2026
Every website you visit can access a limited, deliberate set of information that your browser shares. This is a normal part of how the web works, not spying.
What is visible
Operating system and browser type, screen resolution, language settings, time zone, a rough sense of hardware capacity (core count, RAM), and a general estimate of connection speed.
What is not visible
Your files, your passwords, your screen contents, your camera or microphone (unless you grant permission), and low-level hardware temperatures are never exposed to a website.
