Macs find each other over Bonjour on your own network. Nothing is announced to the internet.
Clips travel directly, peer to peer. They never pass through — or rest on — a server we run.
Every transfer is encrypted between the two Macs. Only your devices hold the keys.
There's nothing to sign up for. No email, no Apple ID sharing, no profile tied to your clips.
No. Discovery and transfer both happen on your local network. If your Macs can't see each other locally, nothing syncs — by design.
AirCopy honors the macOS "concealed" clipboard flag and can ignore password-manager fields entirely — turn it on in Settings → Privacy.
Pairing is explicit and transfers are encrypted end to end, so a new Mac has to be approved before it can send or receive anything.
