 Healthcare companies are sending your data to big tech. A Bloomberg News analysis says people signing up for accounts at UnitedHealth's pharmacy benefit division might have had part of their social security numbers sent to an Adobe marketing service. Websites for units of CVS Health allowed an analytics company, Quantum Metric, to read social security numbers, passwords, and dates of birth. Trackers from Facebook were able to access your birth dates and phone numbers on a website for Cigna's pharmacy unit.
