Also identify any privacy practices mentioned: In carrying out these purposes, we combine data we collect to give you a more seamless, consistent and personalized experience. For example, Cortana can use the favorite sports teams you add to the MSN Sports app to provide information relevant to your interests, or Windows Store can use information about the apps and services you use to make personalized app recommendations. However, to enhance privacy, we have built in technological and procedural safeguards designed to prevent certain data combinations. For example, we store data we collect from you when you are unauthenticated (not signed in) separately from any account information that directly identifies you, such as your name, email address or phone number."}, {'role': 'assistant', 'content': 'This clause is unfair.
