nameservers and proxy for file sharing app

[remote dome]

I can use cloudflare's nameservers and proxy for a file sharing app built in express.js, i asking this question because Google bard said cloudflare don't allow file sharing platform.

Cloudflare's doesn't unless you store the files in something like R2

I use a SFTP server, is it allowed?

[lament viper]

No

Can't even use nameservers?

[lament viper]

Nameservers are okay, just no proxy
