BROWSER EXTENSION
YOUR SURVEILLANCE RECEIPT,
GENERATED AUTOMATICALLY
The extension watches which domains you visit, identifies the surveillance companies
behind them, and calculates what your data was worth — in real time, as you browse.
Click the icon at any time to see your receipt.
↯ Zero data leaves your device.
All processing runs locally. No account. No server.
HOW IT WORKS
01
Install once. The extension runs silently in the background, recording which domains your browser contacts as you browse.
02
Click the icon. Any time you want to see your receipt — after reading the news, after shopping, after anything — click the TunnelMind icon in your toolbar.
03
See the invoice. Every surveillance company that extracted value from your session, what they took, what it was worth, and the exact formula used to calculate it.
04
Clear and repeat. Hit "Clear Session" to reset. Start a fresh session for any site or category of browsing.

COMMON QUESTIONS
Does it upload my browsing history anywhere?
No. The extension stores domain names in your browser's local storage only. Nothing is transmitted. The tracker database (38,000+ domains) is bundled with the extension — no network requests needed to generate your receipt.
How are the dollar values calculated?
Each domain is matched against an industry CPM benchmark (cost per thousand ad contacts), multiplied by a category weight based on the type of data collected, then divided by 1,000 per contact. We always round down — never overstating. Full methodology is shown inside every receipt.
What does "net surveillance profit" mean?
It's the estimated value surveillance companies extracted from your session minus the per-session cost of a TunnelMind subscription ($7/month ÷ 120 avg sessions). When it's negative, you cost them more than they made.
Can I use it without paying?
The extension itself is free to install. Unlimited receipt generation requires a $7/month subscription. There is no trial period, no tricks, cancel any time.
