HushOS vs OneDrive
OneDrive comes with Windows and Office. Microsoft can read what is in it; the Personal Vault adds a lock screen, not encryption you hold.
Side by side
| HushOS | OneDrive | |
|---|---|---|
| Can the company read your files? | No, never. Every file and its name is locked on your device before upload. We cannot read either. | Yes. Files are encrypted on Microsoft’s servers with Microsoft’s keys. Personal Vault asks you to verify your identity again; it does not change who holds the keys. |
| Your password | Never sent to us. Checked on your device with OPAQUE. | Your Microsoft account password is sent to Microsoft to sign in. |
| Sharing | With people, by wrapping the folder key for them on your device under X25519 and ML-KEM-768 together, so it stays shut to a quantum computer later; or by a link with an optional password and expiry. Stopping a share changes the keys. | With people or by link, with passwords and expiry on Microsoft 365 plans. Microsoft can read what you share. |
| Free storage | 2 GiB, and more for every friend you invite. | 5 GB. Personal Vault holds three files on the free plan. |
| Open source | Yes, all of it: the app and the server, under the AGPL. You can read it or run it. | No. |
| Run it yourself | Yes, for free, with a Docker Compose guide. | No. |
| Apps | Web app that installs on any phone or computer. Desktop and mobile apps coming very soon. | Built into Windows; apps for Mac, Android and iOS; Office opens files in place. |
| How it is paid for | None. Paid for by people who buy more storage, and by nothing else. | Microsoft 365 subscriptions and storage plans. |

Moving from OneDrive
Your OneDrive folder is in File Explorer. Drag what you want onto your HushOS Drive in the browser. Large uploads run in the background and resume if you close the tab.
