By ‘offline’ they mean not connected to the internet. So peer to peer communication via wifi or bluetooth or USB or whatever else.

BitChat comes to mind.

Copy files onto Micro SD cards. Smuggle them out of the country or to a contact who has Internet access.

peer to peer RF like bluetooth or IEEE 802.15.4
