In my interpretation, the sentence about "there is no sync model" only means "files are only downloaded to the client device when the client attempts to open() or read() them". I guess means that files will not take any disk space on your device. In my interpretation, files are stored on keybase servers. Is that correct? I agree that the "sync" sentence in the article is confusing and maybe a bit misleading.
