Recommendations
Independent, privacy-first picks that — unlike Dropbox's core sync — encrypt your files so the provider itself can't read them. Choose by your own priorities; each links to a full Dropbox-vs head-to-head.
Dropbox holds the keys to your files, sits under U.S. jurisdiction, and has a long documented incident record. If those are dealbreakers, here are privacy-first options that — unlike Dropbox's core sync — encrypt your files so that the provider itself cannot read them. This is independent editorial comparison, not paid placement; pick by your own priorities (privacy, ecosystem, price, platform support).
The closest like-for-like Dropbox replacement that genuinely can't read your files.
It is the cleanest answer to the central Dropbox criticism in this archive: because Sync.com is zero-knowledge, it cannot hand readable files to a government, an attacker who breaches it, or its own staff — the exact opposite of Dropbox's server-side-key model. It also moves your data out of U.S. jurisdiction.
Zero-knowledge storage inside a Swiss privacy ecosystem (Mail, VPN, Calendar).
Audited, open-source, zero-knowledge, and Swiss — it inverts every structural Dropbox concern (provider-held keys, U.S. jurisdiction, closed source, opaque audits) and lets you verify the claims rather than trust them.
Must stay on Dropbox? Encrypt your files before they ever reach it.
It doesn't replace Dropbox — it neutralizes Dropbox's biggest weakness. By encrypting locally before upload, Cryptomator means a Dropbox breach, a government demand, or AI/data-scanning yields only ciphertext, restoring the zero-knowledge guarantee Dropbox itself doesn't offer.
Zero-knowledge storage built for regulated businesses (ISO 27001, HIPAA).
For organizations bound by HIPAA/GDPR, Tresorit delivers zero-knowledge encryption plus the certifications and data-residency control Dropbox's server-side-key model can't match — so a breach or legal demand can't expose readable client files.
Zero-knowledge storage with the most generous free tier.
Same zero-knowledge guarantee as the others — the provider can't read your files — with the biggest free allowance, making it an easy no-cost way to stop trusting a provider with your decryption keys.
Open-source, zero-knowledge storage — verify the privacy yourself.
Everything Dropbox isn't on transparency: the entire stack is open-source and zero-knowledge under EU law, so you can verify — not just trust — that the provider cannot read your files.
Lifetime storage with optional zero-knowledge — read the fine print.
Only partly: lifetime pricing beats Dropbox's subscriptions, but on privacy pCloud is Dropbox-like by default — you must buy and use the Crypto folder to get the zero-knowledge protection Sync.com/Proton give you everywhere.
