Browser Fingerprint Test
Trackers can identify you without cookies by combining dozens of browser signals. This shows your fingerprint and how unique — and therefore trackable — it makes you. Everything is computed locally.
🧩 What's combined
Canvas & WebGL rendering quirks, installed fonts, screen size, timezone, language, hardware concurrency, device memory, audio stack and more — together they're often unique.
🛡️ Reduce your fingerprint
- Use Tor Browser or Firefox with resistFingerprinting
- Brave's fingerprint randomization
- Avoid niche extensions/fonts
- Keep your browser updated & common
ℹ️ Bits of entropy
Each bit doubles the number of distinguishable users. ~33 bits is enough to single out one person on Earth.
Frequently Asked Questions
Is my fingerprint sent to Speedelly?
No. Everything — canvas rendering, WebGL strings, the SHA-256 hash — is computed in your browser and never transmitted. We don't store it.
What's a good (low) entropy score?
Lower is better for privacy. Under ~18 bits means you blend in with many others; above ~28 bits you're likely unique and easy to re-identify across sites without cookies.
