Most privacy extensions ask you to take “we don’t collect your data” on faith. You cannot check that. We built Shield so you can.
Symvek Shield is now live on the Chrome Web Store. A Firefox build is coming soon.
What it does, for free
- Gives every page an A to F privacy grade you can read at a glance
- Blocks 22,000+ third-party trackers using EasyList and EasyPrivacy
- Auto-rejects non-essential cookie consent banners
- Protects against browser fingerprinting
- Strips tracking parameters from the links you click
- Shows it all in a local dashboard: what got blocked, your scores, weekly trends
No account. No backend. No telemetry. Everything runs in your browser.
The part you can check yourself
The free tier makes zero network calls to us. You do not have to take our word for it. Open your browser’s developer tools, watch the network tab, and browse. You will not see a single request to a Symvek server. The scoring, the blocking, and the cookie rejection all happen on your device.
That choice costs us things most products rely on. We cannot see install counts, which features get used, or when something breaks. We decided that is the point. A privacy tool that phones home is a contradiction, so we removed its ability to phone home.
New in 1.3: the sites you trust are fully trusted
When you add a site to your whitelist, Shield now steps fully out of the way for it at the network layer. The pages you have chosen to trust load exactly as their authors built them, while every other site stays protected. Your trust is yours to grant, and now it means what it says.
Premium, and the one exception
The free tier is the full protection engine and stays free. Premium is $4.99 a month with a 7-day trial, and it adds the deeper tools: fingerprint-attempt alerts, a tracker network graph, 30-day history, site comparison, a printable privacy report, and a one-click GDPR, CCPA, and PIPEDA data-request generator. All of it runs locally.
Here is the one exception. Premium has to confirm you actually paid, so it makes one kind of network call: a periodic license check that sends a one-way hash of your key and a device id, and nothing about your browsing. No URLs, no page content, no identity. The free tier makes no such call at all. We would rather tell you this than have you find it and feel misled.
