When you teleport a folder with KeibiDrop, anyone in the middle sees two devices exchanging encrypted data, and that's all. File names, contents, the folder layout and the size of each file stay inside the encryption.
Only the parts someone opens move, so even the amount of data shows how much was opened, and says nothing about how big your files are. Your internet provider, the Wi-Fi owner and our relay all see the same thing: two devices, when they talk, and how much encrypted data went between them.
Full version, with the limits and the method: Teleport a folder and nobody in the middle sees what's in it
