Have you linked one or more Google digital identity (account) to your PKM? Have you already swiped on the switch applying to Google Ad Targeting privacy setting? Have you realized that the ON/OFF switch commands how Google sells you as a ‘targetable’ audience? Be mindful of the implications. If you turn the switch ON (Green) Google can make money from you. If you turn the switch OFF (Red) it means Google cannot make money from you. Or if it wants, it needs to ask your express consent.
