VaultWallah is built with one non-negotiable principle: your sensitive credit cards, debit cards, and identity documents belong to you and no one else.

All card and document data is encrypted strictly on your physical device using the Web Cryptography API (AES-GCM 256-bit with PBKDF2 100,000 rounds). No card numbers, CVVs, expiry dates, document numbers (Aadhaar, PAN, Passport, Voter ID, Driving License, Insurance, LPG), or master PINs/passwords are ever transmitted to our servers, any cloud provider, or any third party.
