When you use Bing Desktop, you can choose to participate in the optional Bing Desktop Experience Improvement Program that collects information about your computer, searches, addresses of websites you go to, and how you use Bing Desktop. This information helps us to improve the quality and performance of our products and services and to help prevent spam and phishing scams from reaching your inbox. While Bing Desktop is enabled, we collect information to improve search ranking and relevance and the performance of Bing services.
To help protect your privacy, we don't use any of the information collected through this program to identify, contact, or target advertising to you, and we store this information separately from any account information we might have that directly identifies you, such as name, email address, or phone numbers. We anonymize or delete the information collected through this program at eighteen months.
When you install Bing Desktop, you can opt in or out of participating by selecting or clearing the Improve my experience through the collection of how I use Bing Desktop check box before you click Finish to complete the installation.
