Daak

Daak (डाक, "post") moves photos, files, and text between your own devices over your local network. Nothing goes through the internet. Nothing goes through a server. You do not create an account.

Pair two devices once. Scan a QR code and check that both screens show the same number. After that, pick an item and send it.

Features

End-to-end encryption between paired devices.

Local network only. No account and no internet relay.

Files of any size. Daak sends 1 MiB chunks, so memory use stays low.

Send text and photos as well as files.

Works with Daak on macOS and iOS.

Permissions

Camera: scan the QR code when you pair a device.

Local network and Wi-Fi multicast: find your paired devices.

Notifications: show the result of a transfer.

Daak receives files only while the app is running.
