Pick your files
Choose files in RelayPony, or share into it from any other app's share sheet.
Pair by QR
Point one phone at the other's RelayPony QR code. They recognize each other from then on.
Send over Wi-Fi
The file streams straight across your Wi-Fi, encrypted with age. No shared Wi-Fi? It links the phones directly.
It lands
The file shows up in the other phone's Inbox and can save straight to your device.
Built to move files, not collect them.
Every choice points the same way: your files stay yours, and they never touch anyone else's computer.
True peer-to-peer
The file goes directly from one phone to the other. No server sees it, no cloud stores a copy.
End-to-end encrypted
The age protocol encrypts the transfer between the two devices, the same crypto core as AgePony.
Finds devices for you
On the same Wi-Fi, nearby phones appear automatically through local network discovery.
No shared Wi-Fi? Still works
When there is no common network, RelayPony connects the two phones directly.
Share from anywhere
Send straight from RelayPony, or share into it from any other app you already use.
Open source
Apache-2.0, with a frozen, cipher-agnostic wire protocol. Read it, audit it, build on it.
What stays on your phone, stays on your phone.
RelayPony is built so there is nothing to leak. There is no server holding your files and no account tying them to you.
- No server in the path. Files move device to device, never through a machine we run.
- age encryption end to end. X25519 and ChaCha20-Poly1305, pinned to reference behavior.
- Keystore-backed identity. Each device's identity lives in the phone's secure keystore, with trust on first use.
- Honest permissions. Camera for QR scanning, nearby-Wi-Fi for discovery, storage only to save to Downloads.
- No accounts, no telemetry. Nothing to sign into, nothing phoning home.
- Open to inspection. The Android app and the complete iOS core are public under Apache-2.0.
