Sync.com
Zero-knowledge cloud storage with a 5 GB free plan, files on demand for Windows and no family plan.
In short
- The free plan gives 5 GB for one user, with 30 days of version and deleted-file history2.
- Personal 1 TB lists at $12 a month on yearly billing, with a 50% discount in the first year only1.
- Personal Unlimited keeps file versions and deleted files for 365 days1.
- Every individual plan has one user; there is no family plan1.
- Sync says data is always end-to-end encrypted, with keys only you hold6.
Sync.com suits one person who wants private storage with files on demand and selective sync on Windows1,4. The paid plans keep history for 90 to 365 days and let you password-protect links1. The catch is the price: the first-year discount ends and 1 TB renews at $12 a month, and there is no family plan or lifetime option1.
Best for: People who want private storage for one account and a long deleted-file history.
