Cannot edit the post, so here is an update: - I have rechecked and "Location sharing" is off by default, although "Share web & app activity" is on by default and it can include "searches and associated information, such as location and activity from sites, apps and devices .... like Chrome history, for instance..." - I might accidentally forget to turn off "Backup to Google Cloud" when registering because I had to retry the registration several times and was tired. This would explain why sync was enabled. But I don't remember it clearly.
