Black SealOwn your
digital life.
Not the cloud.
A hardware vault for your passwords, documents, private notes, and final instructions. Air-gapped and fully in your control.
A vault for everything that matters.
Passwords, secret notes, and recovery instructions for your family. All kept offline, encrypted, and entirely under your control.
Passwords
Banking, social, crypto, work. All locked behind one 8-digit PIN, encrypted with AES-256-GCM on the device itself.
Documents
Sensitive documents, account numbers, and important records in a vault that never connects to the internet.
Private Notes
Encrypted notes for recovery instructions, personal messages, and anything meant for your eyes only.
IDs & Records
Passport numbers, insurance details, and identification records stored offline where they can't be breached remotely.
Wills & Legacy
Digital legacy instructions for your family. Recovery phrases, account access, and final messages, sealed until needed.
Crypto & Wallets
Seed phrases, private keys, and exchange credentials kept entirely offline. Air-gapped from every browser and hot wallet.
Set up once. Use it for life.
Onboarding takes under five minutes. After that, daily use is just a PIN and a scroll.
First boot, one time
Power on, write down a 24 word BIP 39 phrase, set an 8 digit PIN. The seed never leaves the screen. Once recorded, it's only ever stored as a derived key inside the device.
Save what matters
Add passwords, secret notes, and instructions for your family directly on the device. Everything is sealed with AES 256 GCM the moment you hit confirm. No keyboard, no clipboard, no leaks.
Unlock to read
Eight digit PIN unlocks the vault for daily access. Three wrong tries wipes the device clean. Two minutes idle and it locks itself again.
Backup, only if you want
Optional encrypted backup to a Solana PDA you control. Lose the device? Enter your seed on a new one and restore. Only you can decrypt it.
Under the hood.
Every cryptographic detail, verified and transparent.
Try it yourself.
A full hardware vault simulation in your browser. Real BIP 39 seeds, real AES 256 GCM encryption, real Solana devnet backups. No install, no signup, no tracking.
