Health data you provide to Microsoft health-related products and services, such as fitness data, health history, and other health information, is used to provide those services and improve them. Microsoft has a separate Consumer Health Data Privacy Policy that governs the collection and use of consumer health data in applicable Microsoft products.
Health data is among the most sensitive categories of personal information, and its collection by a technology company through non-medical products creates risks around re-identification, secondary use, and exposure to law enforcement requests that may not be present with traditional healthcare providers.
Microsoft collects a wide range of personal data — including location, voice recordings, search queries, browsing history, and content you create — across all its products and uses this data for advertising personalisation, AI training, and product improvement. Users with a Microsoft account have rights to access, correct, delete, and export their data, and can opt out of interest-based advertising, but many data uses are bundled under broad legitimate interest or contractual necessity grounds that cannot be individually declined. You can review, download, and delete your personal data, and adjust advertising and diagnostic data settings, by visiting the Microsoft Privacy Dashboard at account.microsoft.com/privacy.
