Is it also deleted from brave servers when I manually clear my browser history?
So brave collects our history !!!
Your browser history is just that: your browser history. Brave doesn’t keep a copy of this on their servers so Brave has nothing to delete. Be aware though that your ISP probably will keep a history of the IP addresses you access through their network.
Please tell me more about what you said. I mean, what you said about ISP.
Brave does not collect that information.
