Offline Entropy Manual

Offline Entropy Manual ships printable entropy / seed backup guides as PDFs so you
can create BIP39 entropy without relying on a website or a phone app for randomness.

Pick what you have at hand (dice, coins, playing cards, D8/D16, or a printer and
scissors), follow the matching guide, and keep your seed offline.

The last word of a BIP39 seed (12th or 24th) is a checksum. This app does not
calculate it. Finish that step on a hardware wallet or another airgapped device
you trust. Never enter your seed into a website or a normal phone app.

Bundled documents keep their original authors' terms; app code is MIT.
