Voice recordings and typed content can contain highly sensitive personal information including passwords, private conversations, and confidential business data — their collection for product improvement purposes creates meaningful privacy risk.
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.
