Sam Soft Privacy ShieldHow to stop browser fingerprinting in Chrome
Even with cookies blocked, sites can identify you by "fingerprinting" your device — quietly reading your canvas, WebGL, audio, screen and fonts to build a unique ID. Here's how to shut that down.
What fingerprinting is
Instead of storing a cookie, a tracker asks your browser to render an invisible image or process audio, then hashes the tiny hardware-specific result. That hash is stable enough to follow you across sites — no cookie needed, and clearing your history won't stop it.
How to stop it
- Install fingerprint protection. Add Sam Soft Privacy Shield (free).
- Leave Fingerprint Protection on. It's on by default — it adds imperceptible noise to canvas, WebGL and audio readings and normalises screen/fonts, so your device looks different on every site while pages still work.
- Verify it. Check browserleaks.com/canvas or coveryourtracks.eff.org — your fingerprint should read as randomised/protected.
The engine is built to be undetectable: patched APIs report as native code, so anti-fingerprinting-detection scripts can't tell it's active.

Will this break websites?
The noise is below human perception and pages render normally. If a site ever misbehaves, you can Pause protection on that site with one click.
Is randomising better than blocking?
For fingerprinting, yes — you can't "block" a canvas read the way you block a request, so the fix is to make each read slightly different so the hash never matches.
