After your purchase, you'll receive a license key by email instantly. Install (or open) the ChargeGuardian extension, click the shield icon, go to Settings, paste your key, and click Activate. Pro features unlock immediately — no account or login required.
Check your spam folder first. If it's not there, email support@chargeguardian.io with the email address you used at checkout and we'll resend it.
One-time. $19 gets you lifetime access — no subscriptions, no recurring charges, no hidden fees.
Pro adds the checkout confirmation overlay, scam & phishing detection (including on Shopify and MercadoLibre), a subscription tracker that finds hidden recurring charges, auto-filled dispute letters, spending insights, and the Guardian AI assistant (English & Spanish, runs on-device).
Only if you enable it. Pro can optionally scan WhatsApp Web and Google Messages to flag SMS scams and phishing. This runs entirely on your device — your messages are never sent to us. You can turn it on or off any time in Settings. See our Pro Privacy Policy for details.
If Pro isn't working for you, email us within 14 days of purchase and we'll make it right.
Visit the Chrome Web Store, search for "ChargeGuardian," and click "Add to Chrome." The extension installs automatically.
No. ChargeGuardian never collects, transmits, or stores your credit card numbers or payment details. Your financial data stays on your device. See our Privacy Policy for the full breakdown of what is and isn't stored.
Nothing. The transaction simply isn't processed — it works like a safety gate. You stay in complete control of whether a charge goes through.
ChargeGuardian works on any site that uses standard web payment forms — it detects checkout pages automatically. It's tested on Chrome, Brave, Edge, Opera, and DuckDuckGo.
