@jpthuot03 @mike @tchambers @stevetex @Vivaldi @jon it's a shame, but my search engine led me to reddit:

https://www.reddit.com/r/privacy/comments/kkpb34/does_chromium_send_data_to_google/

In short Chromium (the browser) yes, but for other Chromium-based browsers, it might not be the case

Anyone any better source?
