ChargeGuardian sits between you and the payment button. Nothing changes about how you shop — you just get a final checkpoint.
ChargeGuardian intercepts your click on any payment button — Buy Now, Confirm and Pay, Place Order, you name it.
A confirmation dialog appears showing the detected payment method — credit card, PayPal, whatever it found on the page.
Only proceeds if you say yes. Accidental clicks, surprise charges, and unauthorized purchases are stopped cold.
Everything runs locally in your browser. No accounts, no cloud, no tracking. Just honest protection.
Detects credit cards, PayPal, Stripe, Google Pay, and saved payment methods automatically. No configuration needed.
Install it and it works. No setup, no account, no forms. Just protection.
No data leaves your browser. No tracking, no analytics, no cloud. Everything stays local.
Whitelist your favorite stores to skip the confirmation. One click, no nagging.
Local log of every intercepted payment. Know exactly when and where you confirmed a charge.
Works in English and Spanish. More languages coming soon.
...and any site with standard payment buttons
