SeedCrypt encrypts your mnemonic phrases with AES-256 and stores them on your own media — USB key, external disk. Zero cloud. Zero network. Zero compromise.
Mnemonic phrase
Password
Storage
Your seed phrase gives full access to your crypto wallet. Storing it in plain text — on paper, in a text file, in your notes — is an unnecessary risk.
Fire, water damage, tearing. One incident and your wallet is inaccessible forever.
iCloud, Google Drive, Notion… One account compromise and your seed is exposed.
Automatically synced to your photo backups. Accessible from any connected device.
Military-grade encryption with key derivation resistant to brute-force attacks.
No data ever leaves your device. SeedCrypt blocks the network during all sensitive operations.
Store on USB key, external disk or local folder. Manage multiple locations with automatic detection.
Export your encrypted seeds as QR code or printable PDF for a secure physical backup.
A native app on both platforms. Your encrypted seeds are interoperable between devices.
Progressive lockout after failed attempts. Your seed stays protected even if the device is stolen.
Type your 12 or 24 words directly into the app. SeedCrypt never sends them anywhere — input is local and the network is cut.
This password is the only key to decrypt your data. It is never stored — keep it carefully.
Select your USB key or disk. The encrypted file is saved. Nobody but you can read it.
No subscription. Pay once, use for life.
