Also identify any privacy practices mentioned: Comcast may also share Web Log Data, Preference Data, and Your Data with its affiliates that help it operate the Comcast Web Services, solely to provide you with the Comcast Web Services, other cross-platform products and services, advertising, and promotional offers it thinks may be of interest to you. For example, Comcast will share your Registration Data with an affiliate, so that affiliate can provide you with online access to content from premium networks that are part of your XFINITY TV subscription if you have signed up for that service, and to make you aware of other Comcast products and services it thinks may be of interest to you. This sharing occurs when you sign up for and use these other services, and may be necessary for us to provide them. If you do not want Your Data shared with a specific service, then you may choose not to sign up for that service or stop using it at any time if you have already signed up for it."}, {'role': 'assistant', 'content': 'This clause is fair.
