Military-Grade Encryption

Your security is our top priority. By setting a Master Vault Password (MVP), your entire credential database is encrypted locally using the native Web Crypto API (AES-GCM).

Without your password, the data is just mathematically unreadable gibberish. We never see it, and Google never sees it.
