We may also use public APIs (which allow two applications to talk to each other) to obtain data from public websites, for example, Twitter and YouTube (part of Google, and whose data is not used towards YouGov Signal's daily Sentiment aggregation). Much of this information is non-personal, but it may include social media handles, and associated public posts or comments (but never private posts or account information).</li> <li> <b>Acquisition partners:</b> if you decide to register with an organisation to receive opportunities from companies like YouGov, that organisation will pass your name and contact information to us so we can contact you about joining YouGov.</li> <li> <b>Our clients:</b> who may ask us to combine your data, such as your survey responses, with information they already hold, so they can use the combined data to perform more detailed analysis. We will only agree to do this if we are sure that our clients will not be able to identify you from the combined dataset, or if you have given your consent to be identified.</li> <li> <b>Segmentation partners:</b> we may purchase data from companies which help us to categorise our members’ data into groups or ‘segments’ based on a classification of consumers devised by the segmentation partner.
