Question 1

Is there an AirDrop for Windows and Android?

Accepted Answer

Cynth works like AirDrop but across Windows, macOS, iOS, Android, and Linux on one shared core. It transfers directly between devices, end-to-end encrypted, and — unlike AirDrop — also works across the internet, not only between devices in the same room.

Question 2

Does Cynth work across the internet like AirDrop over Wi-Fi?

Accepted Answer

Yes. AirDrop only works between nearby Apple devices. Cynth transfers on the same network at local speed, but also punches a direct path between devices behind different networks, and falls back to an encrypted relay when a direct path is impossible.

Question 3

Is Cynth as private as AirDrop?

Accepted Answer

Both keep files off the cloud. Cynth authenticates every connection with mutual TLS between per-device keys and encrypts end-to-end on every path; on the same network, traffic never leaves your network, exactly like AirDrop.
