Remove any queries on startup browser

[23rd]

Hi.
I decided to sniff trafic on startup of browser and I found out that CentBrowser is sending queries.
I tested same thing in ungoogled chromium and it was pretty clear startup.
Here is an illustration: https://puu.sh/x8dcX.mp4
"Check updates" is disabled.
Can you say what are these queries and can I remove it somehow? 
It said "Privacy Protection" on home page, but it looks like CentBrowser is sending information somewhere.

Thanks.
