Question 1

What is browser fingerprinting?

Accepted Answer

Browser fingerprinting is a tracking technique that identifies users by collecting unique device data including screen resolution, installed fonts, browser version, GPU information, and system configuration. Unlike cookies, fingerprints persist across private browsing and don't require consent.

Question 2

How does canvas fingerprinting work?

Accepted Answer

Canvas fingerprinting renders text or graphics using the HTML5 Canvas API, converting the result into a unique hash. Variations in font rendering, anti-aliasing, and GPU processing across devices create distinctive outputs that can identify individual browsers.

Question 3

Can VPN protect against browser fingerprinting?

Accepted Answer

VPN masks your IP address but does not prevent browser fingerprinting. Your device characteristics, fonts, GPU data, and system information remain exposed. Effective anti-fingerprinting requires privacy extensions, GPC/DNT signals, and privacy-focused browsers like Firefox or Brave.

Question 4

How is the privacy score calculated?

Accepted Answer

Privacy score starts at 30 points and adjusts based on protections and risks. Active protections like ad blockers (+15), WebRTC protection (+15), and Global Privacy Control (+10) add points. Actual risks like WebRTC IP leaks (-15) subtract points. The system rewards protections rather than penalizing defaults.

Question 5

Is my data stored or transmitted?

Accepted Answer

No. All analysis happens locally in your browser. Your fingerprint data is never stored or sent to any server. You can verify this by checking the network requests in your browser developer tools.

Question 6

How can I protect against browser fingerprinting?

Accepted Answer

Protect against fingerprinting by enabling an ad blocker (uBlock Origin or AdGuard), using privacy-focused browsers (Firefox or Brave), enabling Global Privacy Control and Do Not Track, disabling WebRTC IP leaks, and using a VPN with WebRTC leak protection.
