Microsoft does not share your name or email address with our advertisers. When we deliver a search result or an ad to you, we will send data like your search query, IP address, location, ad configuration, and device identifiers to our advertising partners. We also share aggregate data with our advertising partners.
Even without sharing your name, the combination of search queries, location, device identifiers, and IP address shared with advertising partners can enable re-identification and detailed behavioural profiling by those third parties.
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.
