We manage huge chunks of our life online these days, which means there is a mass of personal data entrusted to a range of different companies. You probably already use Apple privacy tools like App Tracking Transparency, Hide My Email, and iCloud Private Relay, but none of that helps with data that is already out there publicly exposed on the internet.
Even things as seemingly innocuous as our hobbies and interests can be valuable data when it comes to those who want to try to sell us things or – worse – to scam us.
