What steps can individuals take to monitor and track who has access to their personal health data when using health tracking apps and wearable devices?

Individuals can start by carefully reviewing the privacy policy and terms of service of the health tracking apps and wearable devices they use to understand how their personal health data is being collected, stored, and shared. They should also regularly check the permissions granted to the app or device on their smartphone or other connected devices to ensure they are only providing necessary access. Additionally, individuals can set up alerts or notifications for any changes in privacy settings or data sharing practices, and consider using additional security measures such as two-factor authentication to protect their personal health data.
