❓ Frequently Asked Questions
What information does my browser reveal to websites?+
Your browser reveals your OS, screen resolution, timezone, language, installed plugins, GPU model, battery level, network type, and more — often enough to uniquely identify you.
Can websites see my battery level?+
Some browsers expose the Battery Status API, which reveals your battery percentage and charging status. This has been used as a tracking vector. Firefox removed this API for privacy.
How can I limit what websites learn about me?+
Use Tor Browser or Firefox with strict privacy settings. Disable JavaScript to block most fingerprinting APIs. Use extensions like uBlock Origin and NoScript for additional protection.
