Ciphergoat

With ciphergoat, you can protect your recovery seed phrase and other sensitive information from loss or compromise with the most secure open source encryption standards. Run the app offline in a secure environment, encrypt your data with a strong passphrase, and export/import it as a secure QR code (SeQR).
The SeQR code can be stored as an image and can be printed or engraved in metal.
Scan the SeQR code with ciphergoat, enter your passphrase to reconstruct your wallet recovery phrase or your secured notes anytime you need it. Ciphergoat operates offline and we highly recommend you disable your device’s internet connection while using the app.
