Symvek Shield: Privacy Score & Tracker Blocker автор Symvek Technologies Inc.

Shield gives every page you visit a privacy grade from A to F, blocks the
trackers behind that score, and catches something no other blocker can: the
moment a page sends what you just typed to another company.

WHAT SHIELD DOES

Privacy grade: an instant A to F score for every page, computed in your browser.

Tracker blocking: 92,000+ tracker domains from EasyList and EasyPrivacy.

Cookie banners: rejected automatically.

Fingerprint protection: canvas, WebGL, audio and font readings are randomised per site and per session, so the value collected differs every time.

Leak detection and blocking: Shield watches the email, phone and name fields you type into. If a page tries to send that value to a third party before you press
submit, Shield tells you who received it and offers to stop that company, on this
site or everywhere. The rule takes effect immediately on the page you're already
looking at, and one click undoes it.

Names the script that read your field: not "a tracker is present on this page",
which any blocker can say, but "this script read your email field four seconds
after you typed it, and you never pressed submit". A blocker that filters by
destination cannot see a read at all.

Data requests: generate an access or deletion request for any site, ready to send
from your own mail client.

ZERO DATA COLLECTED

The free tier makes no network calls of its own. Open the Network Monitor and
watch: Shield sends nothing, because there's nowhere for it to send anything.
No account, no sign-up, no analytics, no telemetry. Everything happens in your
browser and stays there.

Field contents are read on your device to notice when a page transmits them. The
values are never stored and never leave your machine, and password and payment fields are never inspected.

SHIELD PREMIUM

Protection is free and stays free. Premium is the record that accumulates: every
company Shield watched receive something you typed, every script that read one of your fields, across every site and month, plus a dated export you can attach to a data request. Built only from what your own browser saw.

Also included: import your Google or Meta data export to read the ad profile they
admit to holding, and a guided walkthrough for resetting it.
