; (II) how any user-specific data used by the algorithm is collected or inferred about a user of the platform, and the categories of such data; (III) any options that the online platform makes available for a user of the platform to opt out or exercise options under subparagraph (B), modify the profile of the user or to influence the features, inputs, or parameters used by the algorithm; and (IV) any quantities, such as time spent using a product or specific measures of engagement or social interaction, that the algorithm is designed to optimize, as well as a general description of the relative importance of each quantity for such ranking. (B) The online platform enables users to easily switch between the opaque algorithm and an input-transparent algorithm in their use of the platform. (2) Rule of construction Nothing in this subsection shall be construed to require an online platform to disclose any information, including data or algorithms— (A) relating to a trade secret or other protected intellectual property; (B) that is confidential business information
