When you fire up the Brave browser, it pings Google's servers and starts collecting your data. google doesnt give away multimillion dollar software applications without the ability to capture data with them.

The only way to surf/search without Google identifying you is to use a cloudbrowser. Because you are using a VM and a disposable browser, any search engine is getting incorrect info about you and your searches. It makes Google a private search engine. www.tracefree.com
