Files should just go across.

Why RelayPony exists

Handing a file to the person standing next to you should not mean uploading it to someone's cloud, signing into an account, or handing over your contacts. Yet most "share" buttons quietly route your file through a server you don't control, and the one tool that does it directly, AirDrop, only talks to other Apples.

RelayPony does the obvious thing instead: it sends the file straight from one phone to the other, encrypted the whole way with the age protocol. On the same Wi-Fi the two phones find each other automatically. When there is no shared network, they link up directly. Nothing is uploaded, nothing is stored, and there is no account anywhere in the picture.

How it's built

RelayPony is native Android, Kotlin and Jetpack Compose, over the same carefully verified age crypto core that powers AgePony. There is no shared backend, because there is no backend at all. The transport runs a frozen, cipher-agnostic wire protocol so the format stays stable as the app grows. The whole thing is open source under Apache-2.0.

It is in closed testing on Google Play now. An iPhone version is planned, further out than Android.

The Pony family

RelayPony has siblings, all the same one person, all the same principles:

• PGPony does the full OpenPGP world: GnuPG-compatible keys, hardware smartcards, on-card key generation.
• AgePony brings the age protocol to the phone for encrypting and signing files.
• QuorumPony splits a secret into cards, where any few rebuild it and one alone reveals nothing.

All four sit together on the family page.

The rules

• No accounts. Nothing to sign up for.
• No tracking. No analytics, no telemetry, no ad IDs.
• No server. Your files never touch a machine anyone else runs.
• Free. No in-app purchases, no subscriptions.
