| 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 Google’s servers with Google’s keys. Client-side encryption exists only on some Workspace business plans, set up by an administrator. |
|---|
| Your password | Never sent to us. Checked on your device with OPAQUE. | Sent to Google to sign in, as with any Google account. |
|---|
| 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 viewer, commenter and editor roles. Google can read what you share. |
|---|
| Free storage | 2 GiB, and more for every friend you invite. | Up to 15 GB, shared across Drive, Gmail and Photos. |
|---|
| 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. | Web, Windows, Mac, Android and iOS, with Docs, Sheets and Slides built in. |
|---|
| How it is paid for | None. Paid for by people who buy more storage, and by nothing else. | Storage plans, and Google’s advertising business more broadly. |
