Also identify any privacy practices mentioned: With some challenges, promotions and surveys, we may ask questions so we can conduct market research. Sometimes we will ask questions that we know our business partners are interested to learn. Other times, we will ask questions on behalf of our business partners. In these cases, we may share your responses with these business partners for their own market research and communication purposes. For example, we may ask whether you prefer coffee or tea in the morning, and share your response with our coffee company partner.
