Securely store verifiable purchase credentials and generate Zero-Knowledge Proofs for reviews. VERA Vault is a secure digital vault that allows you to prove you purchased a product and leave verified reviews without ever revealing your identity! VERA Vault for Google Chrome — Private, Anonymous, Secure Store your digital receipts right inside Chrome — no tracking, no personal data sharing, and nothing uploaded to a central server. Everything happens on your own device. Built with cutting-edge cryptography, VERA Vault gives you the power to fight fake reviews and build trust online, while keeping the one-click simplicity people love. Whether you're a privacy-conscious shopper leaving feedback, a buyer protecting your email from spam, or just someone who values digital autonomy, VERA Vault gives you everything you need to authenticate your purchases — privately and securely. WHAT YOU CAN DO • Securely store digital receipts from participating e-commerce merchants locally in your browser. • Prove you actually bought an item when leaving a product review. • Keep track of your verified purchases all in one clean, minimal interface. ZERO-KNOWLEDGE VERIFICATION (THE MAGIC) This is the big one. When you go to leave a review, your VERA Vault looks at your digital receipt and generates an Anonymous Verification Pass using advanced Zero-Knowledge Proofs (ZKPs). This mathematically proves your receipt is authentic and matches the exact product you are reviewing, but strips away your real name, email, and order number entirely. ZERO PERSONAL DATA SHARED Protect your privacy. Your name, email, payment details, and raw receipts stay strictly inside your local Chrome extension. Only a cryptographic proof and your review text are sent to the merchant. It is mathematically impossible to reverse-engineer this anonymous proof back to your identity. SEAMLESS E-COMMERCE INTEGRATION Shop normally. When you checkout at supported merchants, your digital receipt is sent directly to your extension. Weeks later, when you decide to leave a review on the merchant's site, simply click the "Verify Anonymously with VERA" button right inside the review form. The extension automatically pops up and handles the complex math behind the scenes. YOUR SECURE RECEIPT LIBRARY Every digital receipt you receive is kept privately on your device until YOU delete it. From your built-in vault, you can view your verified purchases, check credential statuses, and manage your stored data at any time. PRIVATE BY DESIGN VERA Vault requests a deliberately minimal set of permissions and does not collect or monetize your data. All cryptographic proofs are generated locally on your machine. There's no account to create on our servers and no cloud you're forced into — your shopping data stays yours.
