Duey App

Duey protects your financial data with zero-knowledge encryption. Your vault is encrypted on your device before it ever reaches the cloud. We cannot read it. Nobody can. ZERO-KNOWLEDGE VAULT Your passphrase never leaves your device. Duey uses AES-256-GCM with PBKDF2 key derivation (600,000 iterations), the same standards used by banks and security professionals. Even if our servers were breached, your data would be unreadable. Choose a local vault that never syncs at all, or enable cloud sync. Either way, only you hold the key.
