Question 1

Does Microsoft use my data to train AI models?

Accepted Answer

Yes. Microsoft's policy states it may use your data to develop and train AI models across its products. For Copilot specifically, conversation data is used to train generative AI models in certain markets — but an opt-out is available in the product and on the Privacy Dashboard. For other Microsoft AI systems, the opt-out path is less clear and requires checking product-specific documentation.

Question 2

Can my employer see my files and emails in Microsoft products?

Accepted Answer

Yes, if you are using a work or school Microsoft account. Your employer or school administrator can access and process the contents of your files, emails, and communications within Microsoft products associated with that account. If you leave the organisation, you may lose access to content you created. For personal Microsoft accounts, this does not apply.

Question 3

Does Microsoft share data with LinkedIn?

Accepted Answer

LinkedIn is a Microsoft affiliate. The Microsoft privacy statement permits data sharing with affiliates and subsidiaries for business operations and advertising purposes. The statement does not specify which data flows between Microsoft products and LinkedIn — users are directed to LinkedIn's separate privacy policy for LinkedIn-specific practices.

Question 4

How do I opt out of Microsoft personalised advertising?

Accepted Answer

Visit Microsoft's opt-out page (linked from the privacy statement under 'Control the use of your data for personalized advertising') to disable personalised ads across Microsoft properties and the Xandr ad network. You can also adjust ad settings in the Microsoft Privacy Dashboard. Opting out stops behavioural targeting but does not remove ads entirely.

Question 5

Is Windows collecting data about me in the background?

Accepted Answer

Yes. Windows continuously collects diagnostic and usage data as part of its cloud-based operation. The type and volume depends on the diagnostic data level you select in Windows Settings (Basic or Full on Windows 10; Required or Optional on Windows 11). Per-app privacy controls in Settings allow you to restrict access to your camera, microphone, location, and contacts on an app-by-app basis. The full detail of what is collected at each level is in Microsoft's separate 'Data collection summary for Windows' document.

Question 6

How does Microsoft's privacy policy compare to Apple or Google?

Accepted Answer

Microsoft's privacy posture sits between the two. Apple's privacy model is more restrictive — it collects less data and has stricter third-party tracking limits — and earns a higher grade on Privacy Decoded. Google collects extensively across its ecosystem but provides granular controls. Microsoft's challenge is the sheer breadth of its product surface: practices vary significantly from Windows (extensive telemetry) to Azure (enterprise-grade data processing agreements) to Xbox (entertainment data), and the umbrella policy obscures these differences.
