Everything you need to write about it.

RelayPony sends files straight from one phone to another, encrypted end to end with the age protocol, with no server, no cloud, and no account.

RelayPony is a free, open-source app that sends files directly between two phones. On the same Wi-Fi the phones find each other automatically; with no shared network they connect directly. Every transfer is end-to-end encrypted with the age protocol. There are no accounts, no servers, and no tracking. It is out now for iPhone on the App Store and for Android on Google Play and F-Droid.

RelayPony is a free, open-source file-transfer app for iPhone and Android, built by NorseHorse, a solo independent developer. It sends a file directly from one phone to another instead of routing it through a cloud service. On a shared Wi-Fi network the two phones discover each other automatically using local network discovery; when there is no common network, RelayPony establishes a direct device-to-device link and transfers over that. Every transfer is end-to-end encrypted with the age protocol (X25519 and ChaCha20-Poly1305), the same crypto core used by its sibling app AgePony, and the encrypted stream is carried over a frozen, cipher-agnostic wire protocol. Phones pair by scanning a QR code on a trust-on-first-use basis, with each device identity held in the phone's secure keystore. There are no accounts, no analytics, and no server of any kind. The whole Android app and the complete iOS core are open source under Apache-2.0. RelayPony is out now for iPhone on the App Store and for Android on Google Play and F-Droid, where F-Droid builds the app directly from the public repository, and is part of a small family of privacy tools that also includes PGPony, AgePony, and QuorumPony.
