Sync.com

Storing, syncing and sharing files — much like Dropbox, but with zero-knowledge end-to-end encryption switched on by default, so only you can read your data. That makes it a natural fit for privacy-conscious individuals and small teams who want the familiar Dropbox-style workflow without handing readable files to the provider. You get synced folders across devices, protected share links with access controls and file recovery, all under encryption that Sync.com itself cannot see through.

Paid plans start at US$8/mo on annual billing for generous terabyte-class storage, with a 5 GB free plan to get you started. That puts it among the cheapest fully encrypted options in this comparison — you are getting zero-knowledge end-to-end encryption at a price close to mainstream, non-encrypted clouds. Watch that the headline rate applies to annual billing, and note that data is stored in Canada rather than Australia.

Yes. Zero-knowledge end-to-end encryption is on by default, which means Sync.com technically cannot read your files — the keys stay with you. It is a Canadian company (Toronto, founded 2011), storing data under Canada's strong privacy laws.

Sync.com Inc. is independent — founded in Toronto in 2011 and still privately held by its founders. There is no big-tech parent; the business runs on subscriptions rather than on monetising your data.

Yes — there is a genuine 5 GB free plan with the same zero-knowledge encryption as the paid tiers, and you can expand it through referrals. It is fine for testing the service or keeping a folder of essential documents safely encrypted.

These are the trade-offs of an encryption-first design. There is no block-level sync, so a changed file re-uploads in full — noticeable on Australian upload speeds with large documents. There are no third-party app integrations, the desktop and mobile apps are workmanlike rather than slick, and your data lives in Canada rather than Australia. None of that undermines the security; it is the practical cost of keeping everything zero-knowledge, and for most privacy-minded users it is a fair exchange.
