Access data saved on iCloud.

Hi,

I am trying to view what is backed up on iCloud. I pay for the lowest TB plan because I thought I could, at the very least, access my information and, at most, delete items in bulk much easier than via my iPhone OR save things to my PC. I am specifically looking to access my messages tonight.

What is the point of messages on iCloud if not for the ability to access them on another device? And why have iCloud the app when it is iUseless? (Joke, I love my iPhone but this is pretty ridiculous.)
