Symvek Shield
A privacy browser extension that shows you exactly who is tracking you online and gives you the power to stop them. Built with WXT. Available on the Chrome Web Store and Firefox Add-ons.
What Shield does
Real protection, not privacy theater.
Tracker Blocking
Powered by EasyList and EasyPrivacy filter lists. Blocks ads, trackers, and fingerprinting scripts before they load. See a real-time count of what was blocked on every page.
Privacy Scoring
Every site gets a privacy grade from S (perfect) to F. Instantly understand how a site treats your data based on trackers detected, cookie behavior, and third-party requests.
Cookie Auto-Reject
Automatically rejects non-essential cookies on 100+ consent platforms. No more clicking through confusing dialogs designed to trick you into accepting everything.
URL Cleaning
Strips 60+ tracking parameters from URLs as you browse. UTM tags, Facebook click IDs, Google click IDs, and dozens more are removed automatically so your links stay clean.
Fingerprint protection
Browser fingerprinting identifies you without cookies. Sites probe your GPU, canvas rendering, audio processing, and installed fonts to create a unique ID that follows you across the web. Unlike cookies, you cannot clear a fingerprint. Shield detects and disrupts four fingerprinting techniques:
Canvas noise
Adds imperceptible noise to canvas pixel data before sites can read it. Your canvas fingerprint changes each session, breaking cross-site tracking.
WebGL spoofing
Returns generic GPU vendor and renderer strings instead of your real hardware info. Sites see the same GPU as millions of other users.
Audio disruption
Adds micro-noise to AudioContext output used for audio fingerprinting. The hash changes each session without affecting audio playback.
Font enumeration blocking
Detects rapid font probing and returns randomized width measurements, preventing sites from building a reliable list of your installed fonts.
