Sync.com

Sync.com is end-to-end encrypted on every plan and priced around the terabyte rather than the gigabyte. Personal 1TB keeps 90 days of file history, three times the 30 days on Dropbox Plus, and Pro Solo 5TB stretches that to 180 days. The headline prices are first-year promotions. In the US, Personal 1TB starts at $9 a month billed annually, then renews at $12 a month, so plan around the second figure. It suits someone who wants a private, recoverable copy of a working folder more than slick real-time collaboration.
