QuorumPony Desktop 1.0.0

QuorumPony splits a secret into a set of printable recovery cards. You choose how many cards to make and how many are needed to rebuild the secret, so a 3-of-5 backup survives losing two cards and still cannot be read from any two of them. The math is Shamir Secret Sharing. The cards are yours to print, store, and hand out.

This is the first desktop release. It runs on macOS, Windows, and Linux, with a layout built for a desktop window.

What it does

  • Split. Enter a passphrase or import a file, pick your K-of-N, and get one card per share. Each card carries a QR code and a printed code, and you can export the whole set as a PDF to print.
  • Recover. Gather enough cards back together and rebuild the original secret, then copy it or save it to a file.
  • Check. Confirm a single card is intact and see which backup it belongs to, without rebuilding the secret. This lets you audit a stored card without exposing anything.

Add a card by importing an image or PDF, scanning its QR with a webcam, or typing the printed code. Importing is the most reliable path. Webcam scanning works but depends on your camera. The window uses a two-column layout when it is wide enough and stacks on a narrow one, and you can drag a card file straight onto it.

The app ships in six languages and includes a quorumpony command-line tool for the same split, recover, and check operations.

Privacy

QuorumPony makes no network requests. There are no accounts, no telemetry, and nothing leaves your machine. The one exception is an update check, which is off by default. If you turn it on, it contacts quorumpony.com only to compare version numbers.
