Features
File sync
Changes on one device appear on the others within seconds, with conflict handling for files edited in two places at once.
End-to-end encryption
Files are encrypted on your device before they are uploaded, so only you can read them.
Works everywhere
Native apps for Windows, macOS, Linux, Android and iOS, plus a command-line client for servers.
Version history
Every change is kept for up to a year on paid plans, so you can roll back a file or restore one you deleted.
