I stumbled across Diode whilst looking for ways to do secure off-site backups (to my own equipment at another house) and it feels like a paid-for TOR (Ok, there is a free option)

I'm looking for any real experience as the site has too much marketing lingo in it:

Every Client is secured with a public/private key self-custody identity

And this doesn't seem very dynamic if I want to change something:

Diode’s Blockchain Name System can be used for Client friendly names

And somewhere on the site it infers unlimited storage...!

So, is the free option worth me looking into, or is it a waste of time?
