Does metaquotes log our trade data?

 

I was wondering if they have access or monitor our trades since we use their platform.

Also, I was using the Time and sales in their DOM in mt5 and my trades weren't even showing up on it. I am using futures so the DOM is live, but haven't seen any of my orders show up even when the market is very quiet. The broker says it's metaquotes that needs to answer to this.

 
Why would they? You trade with a broker, and MQ is not one.
