SafeVault: Offline Storage

Your seed phrase. Impenetrable.
SafeVault is the most secure offline vault for your BIP-39 seed phrase. No cloud. No servers. No internet required for seed generation, encryption or decryption.
How it works
Your seed is encrypted with AES-256-GCM — the same open encryption standard used by banks, governments and military worldwide — and a key derived from your Master Password using PBKDF2 with 1.2 million iterations. A password meeting the minimum requirements has over 539 quintillion possible combinations. At 1.2 million calculations per guess, even 1,000 high-end GPUs running simultaneously would take over 2 billion years to brute-force it. Since the encrypted vault only exists on your physical QR Code or SafeVault Card — never on any server — without physical access to one of them, there is nothing to brute-force in the first place. The Master Password never leaves your device and is protected by Face ID and the Secure Enclave.
Secure your vault
Export your encrypted vault as a QR Code to print or save offline, or write it directly to a SafeVault Card via NFC — a physical, reusable encrypted storage card. Without the physical component of your secure vault there is nothing to attack online.
Emergency Recovery
Recover your seed phrase anytime using your encrypted QR Code or SafeVault Card. Without the correct Master Password, the data is mathematically unrecoverable.
Vault Integrity Check
Periodically verify your backups to ensure your seed phrase is always recoverable when you need it most.
No cloud. Ever.
SafeVault never connects to the internet for encryption or storage. Your seed phrase never leaves your device to servers — unencrypted or encrypted.
SafeVault Card
A physical NFC card that stores your encrypted vault. Works as a hardware-backed backup — even if you lose your phone, your seed is safe.
