Our verdict: Sync.com is a straightforward choice if you want cloud storage the provider cannot read, with a Windows app that works like Dropbox. The free 5 GB plan is usable but tight: three share links, no media streaming and no Office previews. There is no Linux desktop app.
About Sync.com
Sync.com stores your files with end-to-end encryption, so only you and the people you share with can read them. The Windows app creates a Sync folder that syncs in real time, and CloudFiles keeps rarely used files online only to save disk space. Vault archives files in the cloud without syncing them to every device, and version history lets you restore older or deleted files.
The free plan includes 5 GB of storage, the desktop and mobile apps, Vault, CloudFiles, camera uploads and file history, on up to 5 devices. Free accounts can have 3 active share links with 20 downloads per link per day and 3 team shared folders, and cannot stream video or preview Office files in the browser. Paid Personal and Pro plans add from 1 TB of storage and longer file recovery; they come with a 30-day free trial.
