The information you provide when you sign up, or when you participate in a survey, is for research purposes only. When you sign up, we collect only limited identifying information that we need to invite you to participate in our surveys -- such as your name (so we can personalize our messages to you), email address, and postal code. This information is never sold or given to outside individuals or organizations. When you complete our surveys, we may collect additional demographic information from you such as age, gender, race, and income (in broad categories). This information is used only to classify and compare responses to survey questions and not to identify you individually. We maintain a strict privacy and confidentiality policy in accordance with established standards of ethical survey research.
