AeroFS

AeroFS encrypts your data end-to-end, and only shares your files with those who you invite. Files are never stored in the public cloud. AeroFS lets you sync all the data on your devices. Because AeroFS does not depend on the public cloud, data syncs directly between devices at the maximum speeds possible. That means that AeroFS works incredibly well not only over the internet, but on a LAN as well. With AeroFS you and your team can sync as much data as you need, for free. Whether it's 10GB, 100GB, or 1TB, AeroFS lets you sync all the data, to all of your devices. No caps, no file size limits.
