The best private iCloud alternative for a Mac
If you are leaving iCloud in 2026 and want privacy that holds, pick a provider that encrypts on your Mac and never holds the keys. That is beebeeb — zero-knowledge on every tier, hosted in Falkenstein, Germany, open-source clients — with Proton Drive, pCloud and Sync.com as the strongest runners-up.
Why are people leaving iCloud?
iCloud is not a bad product. It is the path of least resistance on a Mac, and Apple earned that. The friction is specific.
The encryption is opt-in. By default iCloud runs Standard Data Protection, which means Apple holds keys that can decrypt your photos, Drive files, Notes and backups. End-to-end encryption exists only if you switch on Advanced Data Protection (ADP) yourself, set up a recovery contact or key, and accept that Apple can no longer help you recover the account. Most people never flip it. And in February 2025 Apple removed ADP for new UK users after a secret order under the Investigatory Powers Act demanded backdoor access. An opt-in feature can also be a withdrawn one — that is the part the marketing never mentions. Our side-by-side on iCloud's encryption model walks through exactly what ADP does and does not cover.
The ceiling is 12 TB. iCloud+ tops out there, at $59.99/month. A photographer with a decade of RAW files hits that wall and has nowhere to go inside Apple.
You pay monthly, full price, forever. Apple offers no annual billing, so there is no 16–17% discount the way Google One, OneDrive and Dropbox give you for paying yearly.
Concede the obvious: at small tiers iCloud is genuinely cheap. $0.99 for 50 GB and $2.99 for 200 GB undercut almost everyone. If you store a phone backup and some photos and you turned ADP on, stay. This is for the people it stopped being enough for.
Is there a private cloud that works like iCloud on a Mac?
Close, with one honest caveat. A truly zero-knowledge provider decrypts on your device, which makes iCloud's server-side conveniences — datacenter photo search, instant cloud thumbnails, OS-level Optimize Storage — harder to copy, because the server cannot read your data to do that work. That is the real trade, not a footnote. What you get back is a provider that mathematically cannot read your files, hand them to a government, or lose them in a readable breach.
On the Mac specifically: beebeeb runs in any browser and ships the bb CLI today, which gives you WebDAV access and scriptable sync. A native macOS app with Finder integration is coming soon, not shipped — said plainly so you can decide now. pCloud has the most polished Mac virtual-drive feel of this group. Sync.com and Proton both ship working Mac desktop apps today.
The four alternatives, compared
| Provider | Zero-knowledge by default | Open-source clients | Jurisdiction | Storage ceiling | Mac desktop app |
|---|---|---|---|---|---|
| beebeeb | Yes — every tier incl. Free | Yes (clients) | Netherlands / data in Falkenstein, Germany | Up to 99 TB self-serve, quote beyond | Coming soon (web + CLI today) |
| Proton Drive | Yes — every tier | Yes | Swiss (publicly weighing a move over a proposed surveillance law) | ~3 TB (Family) | Yes |
| pCloud | No — Crypto is a paid add-on | No | Switzerland / EU | 10 TB (lifetime) | Yes (mature) |
| Sync.com | Yes | No | Canada (PIPEDA) | 6 TB+ (business) | Yes (no Linux) |
| iCloud (reference) | No — ADP opt-in | No | USA (Apple) | 12 TB | Native |
beebeeb — zero-knowledge as the default, not a setting
The structural difference from iCloud is the default. You do not opt into encryption; there is no other mode. Files are encrypted client-side with AES-256-GCM. At login and recovery your key is stretched with Argon2id at a 256 MiB memory cost (that cost is the login/recovery key-stretch, not a per-file tax). Sharing uses X25519 per-share key wrapping, login is OPAQUE so your password never reaches the server, and recovery is a BIP39 phrase you hold — keys are zeroized from memory after use. Pricing is one flat rate: €10.99 per extra TB up to 99 TB self-serve, custom quote beyond, so the math stays legible at any size. The product clients are open source, which makes those crypto claims checkable rather than asserted. An independent audit is planned and its findings will be published; until then, read the code. Live today: encrypted sharing with expiry and revocation, file requests, file versioning with configurable retention, TOTP 2FA and passkeys. Native Mac and mobile apps are coming soon. How beebeeb's encryption works covers the full key model. The Free tier is 5 GB and zero-knowledge if you want to test the workflow before moving anything across.
Proton Drive — the closest peer on principle
Credit where it is due: Proton matches beebeeb on the two things that matter most, zero-knowledge by default and open-source clients. If you already live in Proton Mail and Calendar, Drive is the obvious move, and the Mac app is real today. The honest limits are storage and jurisdiction — the Family plan caps around 3 TB, so heavy archivers hit a ceiling, and Proton is Swiss — and has publicly discussed moving infrastructure out of Switzerland over a proposed Swiss surveillance law. For most Mac leavers, Proton and beebeeb are a genuine toss-up. Pick on the storage ceiling and which jurisdiction you prefer.
pCloud — best Mac drive feel, read the encryption fine print
pCloud Drive is the most iCloud-like thing here: a virtual disk in Finder that streams files without filling your SSD, and the lifetime plans (2 TB around $399, 10 TB around $1,190 one-time) are compelling if you hate subscriptions. The catch a Mac switcher must not miss: pCloud is not zero-knowledge by default. Client-side encryption requires the paid pCloud Crypto add-on — roughly $49.99/year or about $150 as a lifetime fee. Without it, pCloud holds your keys, which is the exact posture you are leaving iCloud to escape. Excellent drive app; encryption is an upsell.
Sync.com — solid zero-knowledge, narrower platform reach
Sync.com is zero-knowledge by default on every plan, with a working Mac app and straightforward pricing (2 TB around $96/year). It is Canadian, governed by PIPEDA rather than GDPR, which some EU buyers will weigh. The notable gaps are no native Linux client and a few sharing restrictions that surprise people who skip the fine print. For a Mac-only household it is a reasonable, private choice.
What does leaving iCloud actually involve?
The migration is the part nobody warns you about. iCloud Photos, iCloud Drive and Apple's app data live in formats that do not all export cleanly. Pull Photos via the desktop Photos app or icloud.com, move iCloud Drive contents out of the synced folder before you disable it, and keep both systems running in parallel for a week so nothing falls through a gap. With an open-source client and a flat per-TB price, "you can always leave again" stays verifiable instead of promised — the same property that made iCloud's lock-in worth escaping. The full switching walkthrough lives in our iCloud alternatives guide.
Be clear-eyed about one thing: Apple's ecosystem stickiness is real. Handoff, the unified Photos library, automatic device backups — a third-party cloud will not reproduce all of it. The trade you are making is that convenience, for files only your devices can read.
