"We may share aggregated, non-personally identifiable information publicly"

When lots of people start searching for something, it can provide very useful information about particular trends at that time. For example, research has shown that certain search terms are good indicators of flu activity. So with Google Flu Trends we use aggregated Google search data to estimate current flu activity around the world in near real-time and share the information publicly. We hope that our up-to-date influenza estimates may enable public health officials and health professionals to better respond to seasonal epidemics and pandemics. Learn more.
