Take yourself off the market

You can't sell what
you can't collect.

Jammit blocks trackers, sends legal opt-out signals, and scrambles your fingerprint — so data brokers are left with nothing worth selling.

How it works

Three ways to disappear

Most tools stop at blocking ads. Jammit attacks the data-broker supply chain from three directions at once.

🚫

Block the trackers

150+ trackers, ad exchanges and data brokers — Google, Meta, TikTok, Criteo, LiveRamp, Oracle and more — blocked before they load. No data collected means nothing to sell.

⚖️

Opt out, legally

Jammit attaches Global Privacy Control and Do-Not-Track to every request. Under CCPA/CPRA and similar laws, businesses that receive GPC must treat it as an opt-out of selling your data.

🎭

Break your fingerprint

Can't be tracked by cookies? They fingerprint your device. Jammit feeds them a consistent-but-fake identity across canvas, WebGL and audio — and lets you reset it anytime.

📊

Honest numbers

Every stat — trackers blocked, pages protected — reflects a real event in your browser. No invented figures, no fake "value" counters. Ever.

Data brokers make money on coverage. Every person who blocks, opts out, and goes unfingerprintable removes one more profile from the market. Enough of us, and the well runs dry.
