Your files.
Their device.
No one in between.
OneSpace sends files from your device to theirs, end-to-end encrypted. Nobody in between can read them, not even us. Subscribe monthly or yearly, or buy the lifetime license once.
Privacy isn’t a setting. It’s the architecture.
End-to-end encrypted, all the way
Files are locked on your device and only open on theirs. On the way, our servers only route them to the recipient in encrypted form, so there is no readable file to breach, subpoena, or scan. A readable copy exists in exactly two places: yours and theirs.
Your keys, your control
Encryption keys are generated on your device, and our servers only ever hold them sealed. OneSpace cannot read your files, and neither can anyone who asks us to. Not a policy promise, a mathematical one.
Every platform, one license
Windows, macOS, iOS and Android: one license covers them all. Send from your desk, receive on your phone, and keep the same private line across every device you own.
Watch a file take the private line.

Nobody in between can read it. Not even us.
Everything you’d want to check before trusting a transfer tool.
End-to-end encrypted
Your file is locked on your device and only unlocks on theirs. On the way, our servers only route it to the recipient in encrypted form.
Zero-knowledge keys
Keys are created on your devices, and our servers only ever hold them sealed. We couldn’t read your files if we wanted to. We built it that way on purpose.
No cloud locker
No readable copy on our servers. Ever. Files only pass through in encrypted form, so there’s no readable file anywhere to breach, subpoena, or leak.
Every platform
Native apps for Windows, macOS, iOS and Android. One license covers every device you own, mixed however your life works.
Unlimited transfers
No size caps, no monthly quota, no throttling. Send the whole project, not a compressed shadow of it.
Pay the way you prefer
Subscribe monthly or yearly, or buy the lifetime license once and never renew.
Want a feel for it first? Try the browser demo.
The web demo encrypts a file in your browser and hands it over through our broker, and the link expires after 24 hours. It’s a taste of OneSpace. The full product goes further: contacts, groups and sync, with the same end-to-end encryption.
