Self-custody backup

Encrypt your recovery phrase on this device — and nowhere else.

Type or paste your 12 or 24 words, lock them with a passphrase only you know, and download an encrypted file. The words never touch a server. There is no account, no database, no admin who can read them.

This passphrase is the only key to the backup. If you lose it, the file cannot be recovered by anyone — including us. Store it separately from the file.

Your phrase is encrypted before leaving your device — the server only sees ciphertext.

Encrypted backup downloaded. Keep the file on an offline drive and your passphrase somewhere separate. Test it now in the Restore tab before relying on it.
