Journal and Expert tabs, can brokers pull the data there off my account?

 
Hi. I am working on developing my first EA, just applying what I learned so far, and I was paying attention to the Journal and Expert tabs on mt4. I was wondering, can the broker pull this data off my account if they wants to? Because these tabs clear out when I login from a different device on the same account 

just for general knowledge.

Thank you
 
Thank you for your reply 

Also, if my expert advisor takes market orders, does the broker know whether it was a manual trade or EA that opened the trade?
