What is PaperVault.xyz?

PaperVault.xyz is a free, open source tool for creating secure offline vaults for your passwords, 2FA codes, crypto keys, and other sensitive data. Everything happens in your browser - we never see your data. The entire application is available under the MIT License at github.com/boazeb/papervault.

How it Works

  • All encryption happens in your browser (client-side)
  • We never have access to your vault contents or keys
  • You get printable QR codes for offline storage
  • Uses threshold cryptography for social recovery
  • Works completely offline once downloaded

Your Responsibilities

Since PaperVault.xyz works offline and we can't access your data, you're responsible for:

  • Backup your vaults: Print and store your QR codes safely
  • Distribute key shares: Give shares to trusted people according to your threshold
  • Test recovery: Make sure you can unlock your vaults before storing important data
  • Legal compliance: Only store content that's legal in your jurisdiction
  • Security: Keep your printed materials secure and private

What We Cannot Do

We cannot recover your data. This is by design for your security. If you lose your vault backups and key shares, your data is gone forever.

Open Source License

PaperVault.xyz is released under the MIT License. This means you can:

  • Use it for any purpose (personal, commercial, etc.)
  • Modify the code however you want
  • Distribute your own versions
  • Run your own instance of PaperVault.xyz

The only requirement is to include the original license notice. See the full license at github.com/boazeb/papervault/blob/main/LICENSE.
