This is for sharing, with no account/password required. The uploaded data is made available at a web page. If you choose “public”, it will be included in a public index; the only other option right now is “unlisted”. Unlisted pages aren't in the public index, but are available to anyone who has the link.

For very sensitive data, that you would want to password-protect, don't upload it right now. We may offer accounts and/or password-protected data in the future.

Thanks!

I assume you didn't ask that question for images posted to imgur, plaintext files posted on pastebin or comments posted on HN.

A business model that might work for enterprises (assuming they find the tool useful)
