Encrypted before it leaves your device
File contents and even file and folder names are encrypted on your device with keys only you hold. Our servers store ciphertext and nothing else.
End-to-end encrypted cloud storage
Your cloud. Your keys. Nobody else's.
StorageSync encrypts your files on your device before they upload. Even file names. We store ciphertext and could not read it if we wanted to.

Everything you expect from cloud storage, without the trust fall
Sync that just happens
Drop a file into your sync folder on the Mac, or onto the StorageSync window, and it shows up on your iPhone, iPad and in the browser within seconds.
Feels like a local folder
Files app integration on iPhone and iPad, Finder badges on the Mac, and a full web app for any computer.
Camera backup and memories
New photos and videos upload automatically over Wi-Fi, with cellular optional, and the app tells you plainly when backup is paused and why. A Photos timeline on the web, and On this day memories on your phone, from dates only your devices can read.
Albums with everyone's photos
Make one link for a wedding or a trip and everyone adds their photos from any browser, no account needed. On the Family plan, share an album with the family: it's encrypted to each member and grows as you add photos.
Someone you trust can get in
Name up to three people who can unlock your account if you can't. You choose the waiting period, you can say no at any time, and your key is wrapped to theirs on your device: we never hold it.
A vault for the things that matter most
A folder behind its own PIN, even on a signed-in device, with your two-factor codes and saved logins inside it. Codes are computed on your device; the server sees only encrypted bytes.
Share with a link
The decryption key travels inside the link, never through our servers. Add a password and an expiry, and revoke it any time.
Never lose work
Conflicts keep both versions. Version history keeps 30 days on Free and six months on Plus, and the newest three versions of every file stay however old they are. Every transfer is hash-verified.
Works offline
Keep working in your sync folder without a connection. Changes sync in order when you are back online.
Add devices without typing passwords
Approve a new device from one you already trust. Sign in with Apple or Google if you prefer; your keys stay on your devices.
A link that only you can unlock
The decryption key lives in the part of the link browsers never send to a server. Add a password and an expiry, and revoke the link any time.
Deleted doesn't mean gone
Trash and version history come with every plan, and a conflict keeps both versions, so a mistake on one device doesn't cost you the file. On Plus, Rewind puts your whole account, or one folder, back the way it was at any moment in the past six months, and you can undo it. Compare plans →
Built for the Mac, too
A native Mac app with a menu bar status, Finder badges and drag and drop. Everything in your sync folder stays up to date on its own, with version history and Trash behind it. It's in testing and coming soon to the Mac App Store.
Honest limits
iOS does not allow an always-on background sync. While the app is open it syncs in real time; in the background it catches up when nudged and the next time you open it. And because only you hold the keys, if you lose both your password and your recovery code, nobody can recover your files. That is the point.
Treated like a customer, not a suspect
We can't see what you store, so we don't scan it, and no algorithm can lock your account. If we ever have to act on a report, a person decides, tells you why, hears your side and gives you at least 30 days to download your files. We never delete an account for being quiet. Read the terms →
Over your storage? Nothing is deleted
If you go over your plan, uploads simply wait until you free up space. Your files stay put, and your own sync and downloads keep working.
