ChargeGuardian

ChargeGuardian stops you from getting scammed at checkout — before you click pay. Works in English, Spanish, German, and French — it detects your language and warns you in your own words. WHAT IT DOES (FREE) - Warns you before you complete a suspicious checkout - Detects hidden subscription traps and free-trial catches - Flags known scam websites - Works on most checkout pages - Free, no account required WHY IT MATTERS Online checkout pages are designed to move fast — sometimes too fast. Scam sites, fake invoices, and shady subscription terms rely on you not reading the fine print. ChargeGuardian reads it for you, and steps in with a plain-language warning when something looks off. OPTIONAL PRO UPGRADE Pro adds deeper protection: - Warnings about lookalike sites that imitate well-known brands - Crypto scam warnings - Fake invoice and payment-hold phishing warnings - Warnings when a seller pushes bank-transfer-only payment - A check for very new websites - Scam link warnings in WhatsApp Web Pro is a paid upgrade purchased and activated at chargeguardian.io/pro (one-time or subscription, shown at purchase). No separate extension to install. PRIVACY ChargeGuardian does not collect your card numbers, and it never sells or shares your browsing history. Preferences are saved in your browser's extension storage, which Chrome may sync across your devices if you have Chrome sync turned on. Free features run entirely in your browser. Pro's domain-age check looks up only the website's hostname in public domain registries (RDAP). Pro license checks send only your license key to ChargeGuardian's license server (cg-license-api.vercel.app), which verifies it with our payment provider, Whop. Built by someone who got tired of surprise charges and wanted a real answer.
