What are some red flags to look out for when reviewing the privacy policies and terms of service of mobile health apps and online symptom trackers to ensure the protection of personal health data?

When reviewing the privacy policies and terms of service of mobile health apps and online symptom trackers, some red flags to look out for include vague language around how personal health data is collected, used, and shared. Additionally, be wary of apps that do not clearly outline how they secure and protect sensitive health information from unauthorized access. Another red flag is apps that require excessive permissions or access to other unrelated data on your device. Lastly, be cautious of apps that do not provide a clear process for users to request the deletion of their personal health data.
