Delete Agreement created by the free Acrobat Reader

I used the free Fill & Sign feature of the free Acrobat Reader DC to sign an agreement and send a read-only link to someone else to read the signed agreement.  Now the agreement is accessible via this Adobe website for anyone with the link.  I don't want that document to be available anymore. I want to delete it completely from Adobe and the Internet.  How can I do that? 

The only option is to "Hide" but that's not sufficient for me.  I don't want Adobe to continue to have a copy of the agreement, which contains sensitive information.  I've never signed up for Adobe Sign and I don't plan to.  So, I can't login to Adobe Sign.  This is agreement is only a result of the free Fill & Sign feature of the free Acrobat Reader.

Please help.  Thanks.
