Privacy Architecture
No analytics. No tracking. No selling. Here's the honest breakdown of what runs where.
Checkout confirmation, brand/crypto patterns, and WhatsApp scanning all run locally in your browser.
Uses public RDAP registry lookups for the domain only — cached ~24h. Not your full browsing history.
Domain-age lookups are limited and Pro-only. Everything else is clearly labeled. We don't pretend "nothing ever leaves the device" when it does.
Install and you're protected. No sign-up, no cloud accounts, zero configuration required.
Straight Answers
Any extension that touches checkout pages deserves extra scrutiny — including this one. Here's exactly what we ask for, and why.
ChargeGuardian asks to run on every site. That sounds broad, and it's a fair thing to question. Here's the reason: scams and surprise charges don't only happen on big, known stores. They happen on small merchants, brand-new domains, and checkout pages we've never seen before. To catch a wrong charge or a spoofed checkout anywhere, the extension has to be able to look anywhere.
Having permission isn't the same as constantly watching. ChargeGuardian stays dormant until it detects a checkout or payment flow. It's not logging your browsing, building a profile, or recording what you read.
Checkout interception and core scam checks run locally in your browser. Your card numbers and payment details are never collected, stored on our servers, or sold.
Only the Pro domain-age feature uses the network — for public RDAP registry lookups on the domain being checked. That's it. No other features phone home.

ExploringThe Person Behind It
ChargeGuardian isn't a faceless security company. It's an independent project started by one person, Jason Taylor, after watching people lose hundreds of thousands — even millions — to preventable scams. The question behind every feature is the same: does this help people stay safe without getting in their way?
Being small and independent is a fair thing to ask about, so here's the honest version:
"I have seen friends and cohorts lose hundreds of thousands, even millions, to scams. With so much of this happening these days, more protection is needed. Every feature starts with one question: does this help people stay safe without getting in their way? Payments. Messages. Crypto. If something feels off, we flag it. That's the job."
