Is Hub Protect end-to-end encrypted?

I am interested in the Hub Protect service for backups but only if my data is end-to-end encrypted (client-side, with Hubitat cloud not having the key). I've searched the forums and read the docs and have been unable to determine if this is the case. I don't think it is. Just wanted to confirm.

Thx

Yes and I think you can even set a password....

Optional cloud backup password:
