Uninstalling Chrome does not always remove your Chrome profile…you must choose to delete your browsing data during the uninstallation process to remove it from your computer. If you are signed into a Google Account and syncing your data, some profile information will remain on Google’s servers. To fully remove profile data from your machine, you must select the option to delete browsing data during Chrome’s uninstallation, or manually delete the Chrome profile folder on your computer’s hard drive.
