Signing in to Microsoft account: When you sign in to your Microsoft account, we create a record of your sign-in, which includes the date and time, information about the product you signed in to, your sign-in name, the unique number assigned to your account, a unique identifier assigned to your device, your IP address, and your operating system and browser version. Here are a few snippets from their statement:Ĭreating your Microsoft account: Some data you provide, such as your display name, email address, and phone number, can be used to help others find and connect with you within Microsoft products. We mentioned the wording of the Microsoft Privacy Statement regarding Cortana earlier, and the wording of their Microsoft Account section isn't much better. The service started life as a cloud-based storage solution, but its list of features has grown exponentially, and it now offers Microsoft Account users a lot of benefits that extend beyond instant access to their files. Using a Microsoft Account on Windows also unlocks the full potential of OneDrive.

Scary, huh? We'll come back to that later. On iOS and Android devices, Cortana only works when you sign in.

If you don’t sign in, or if you choose to sign out, your experiences will be more limited and they won’t be personalized with your Cortana data. If you choose not to sign in to Cortana in Windows, you can still chat with Cortana and search the web, as well as documents and emails stored in Microsoft services like OneDrive, and Outlook, and on your Windows device. You’re in control of how much data you share with Cortana.

To provide you with personalized experiences, Cortana learns from certain data about you, such as your searches, calendar, contacts, and location. As Microsoft writes on its own website, the reason Cortana currently needs you to use your account is because:Ĭortana works best when you sign in and allow the use of data from your device and from Microsoft services, as well as from third-party services and skills you choose to connect. The catch is that Cortana needs you to use a Microsoft Account for it to function.
