Is my health data secure?

Yes. We use industry-standard security practices including encryption in transit and at rest, access controls, and regular security audits. We never sell your personal information to third parties. Your data is only shared with trusted service providers necessary to operate the app (like database hosting and analytics) - never for advertising. If we use data for research or product development, it's only in anonymized or aggregated form. You have full control: you can access, correct, or request deletion of your information anytime. To delete all your data, go to Profile and tap "Delete account".
