Symvek Shield: Privacy Score & Tracker Blocker

Privacy scores for every site you visit. Blocks 22,000+ trackers, auto-rejects cookies, detects fingerprinting. Zero data collected.

Every website is watching you. Now you can see exactly how much. Symvek Shield gives you an instant A-F privacy grade for every page you visit. It blocks over 22,000 trackers, automatically rejects cookie consent banners, and shows you a real-time dashboard of your privacy: all without sending a single byte of your data anywhere. This is not just another ad blocker. Symvek Shield makes the invisible visible. PRIVACY SCORE ON EVERY PAGE Every website gets an instant A-F privacy grade displayed right on the extension icon. The score is based on: - Number of third-party trackers detected - Whether the connection uses HTTPS - Cookie consent behavior - Overall data collection footprint Click the icon to see the full breakdown: your grade, the exact number of trackers blocked, connection security status, and a list of every tracker found on the page. TRACKER BLOCKING (22,000+ TRACKERS) Symvek Shield uses EasyList and EasyPrivacy, the same trusted filter lists used by Brave, Opera, and Vivaldi, to block trackers across four categories: - Advertising trackers (ad networks, retargeting pixels) - Analytics trackers (page analytics, session recorders) - Social media trackers (share buttons, embedded widgets) - Fingerprinting scripts (canvas, WebGL, font enumeration) Blocking runs through Chrome's declarativeNetRequest API for maximum performance and minimum battery drain. No background page constantly running: just fast, efficient rules that Chrome enforces natively. AUTOMATIC COOKIE REJECTION Stop clicking "Reject All" on every website. Symvek Shield detects and auto-dismisses cookie consent banners from the major consent management platforms used across the web, so you do not have to interact with them yourself. By default, only strictly necessary cookies are accepted. Everything else (analytics, advertising, social) is rejected before you even see the banner. FINGERPRINT PROTECTION Beyond blocking known fingerprinting scripts, Symvek Shield actively defends the browser APIs sites use to identify you. It adds subtle, randomized noise to canvas, WebGL, audio, and font readings, so the signature sites try to build keeps changing and cannot be used to track you across the web. This runs by default, for free, on every site (whitelist the ones you trust). Premium does not add the protection. Premium shows you who tried. PRIVACY DASHBOARD Open the full-page dashboard to see the bigger picture: - Weekly tracker count: how many trackers were blocked this week - Sites visited with per-site privacy grades - Average privacy grade across all your browsing - Cookies auto-rejected count - Top trackers: a bar chart of the most frequently encountered tracking domains - Recent site history with grades, tracker counts, and timestamps The dashboard auto-refreshes so you always see current data. THE MIRROR: SEE WHO IS WATCHING YOU, RIGHT NOW The Mirror is Shield's live counter-surveillance layer, and it is free. It shows you, in the moment, who is trying to profile you and what Shield did about it. - Session-replay detection: some sites record everything you do, every keystroke, mouse move, and scroll, and stream it to a replay vendor for playback. Researchers have caught these tools leaking passwords and card numbers. Shield recognizes 16 of them (FullStory, Hotjar, Microsoft Clarity, LogRocket, and more), names the one recording you, and can block the upload so the page still works but your session never leaves your browser. - Fake-reject alerts: when you reject a cookie banner, some trackers fire anyway. Shield rejects consent for you, then catches the trackers that ignore your choice and names them. SETTINGS AND CONTROL You are always in charge: - Toggle tracker blocking on or off globally - Toggle cookie auto-rejection on or off - Whitelist specific sites that you trust or that break with blocking enabled - All preferences stored locally in your browser HOW IT WORKS 1. Install Symvek Shield: no account needed, no setup 2. Browse normally. The extension icon shows an A-F grade on every page. 3. Click the icon to see tracker details and your weekly stats. 4. Open the dashboard for a full privacy overview. 5. Adjust settings if you want to whitelist sites or toggle features. All scoring, blocking, and analysis runs inside your browser. No analytics, no cloud, no telemetry. Your browsing data never leaves your machine. ZERO DATA COLLECTION, VERIFY IT YOURSELF Symvek Shield collects none of your browsing or personal data. The free tier has no backend, no analytics, no telemetry. Every computation happens in your browser. Your browsing history never leaves your machine. Check for yourself: on the free tier, open DevTools and watch the network tab. You will see zero requests to our servers. That is our proof. (Premium adds one thing: a periodic license check that sends a hashed key and device id to confirm your subscription, and nothing about your browsing.) PREMIUM ($4.99/MONTH, 7-DAY FREE TRIAL) Symvek Shield Premium is the layer that does something about what the Mirror shows you: rebuild the ad profile the platforms have built on you, erase it, keep it erased, and go deeper on the analysis. Every premium feature analyzes your data locally in your browser. The only thing Premium sends to our servers is a periodic license check (a hashed key and device id) to confirm your subscription, never your browsing. - Shadow Profile: import your own data export from Google or Meta, and Shield rebuilds the ad-targeting profile each platform admits to holding, in plain language. It is the profile they confess to, a floor and not a ceiling, and Shield tells you so. - Reset your ad profile (starve and wipe): a guided way to reset your own ad profile at Google and Meta. Turn off further profiling, and clear the interests and advertiser lists they already built. Every step links to your own account settings, the same clicks you could make by hand, sequenced for you. - Maintenance reminders: Google and Meta rebuild your ad profile over time, so a one-time reset fades. Shield remembers when you last reset it and flags when it is due again, on a cadence you choose. It only stores the date; it never acts for you. - Mirror history: a running record in your dashboard of who profiled you over time and what Shield did about it. - Fingerprint detail: the free tier already protects you from fingerprinting; Premium shows you exactly which sites tried and which methods they used (canvas, WebGL, AudioContext, font enumeration), all factored into your privacy score. - Tracker Network Graph: interactive visualization showing which companies track you across sites. See how Google, Meta, and others follow you across the web. - 30-Day Trends: extended analytics showing how your privacy improves over time. Daily snapshots, trend insights, and sparkline charts. - GDPR/CCPA/PIPEDA Request Generator: one-click data access and deletion requests, pre-addressed to the right privacy contact for major data collectors, with a fallback for any site. Opens directly in your email client. No server involved. - Site Comparison: see your best and worst privacy sites side by side. - Privacy Report Export: generate a printable privacy audit of your browsing. Your data, your report, your choice who to share it with. The free tier is the full protection engine, the live Mirror feed, and fingerprint protection. Premium is the act-on-it layer: rebuild and erase your ad profile, keep it reset, and analyze the surveillance over time. It never paywalls the protection itself.
