Facebook, for instance, is alerted every time a person opens the app, essentially signaling to the social media company how often we were going to a “session” and when we booked our appointments. (To confirm Facebook’s retention of this information, we downloaded personal data from Facebook and identified the associated records from Better Help.) During a session with a therapist, we found that metadata from every message, though not its contents, was also sent to the social media company, meaning that Facebook knew what time of day we were going to therapy, our approximate location, and how long we were chatting on the app.
