In simple English
This program runs your own private cloud storage on your own hardware. You can store your files, contacts, and photos there, and reach them from any phone or computer. It keeps your data out of public cloud services and under your physical control. The software is free to download and run, but you need a server or a computer that stays powered on. It takes time to set up and regular maintenance to keep secure.
