OpenAI updates U.S. privacy policy to formalize data-sharing with advertisers and marketing partners

OpenAI updated its U.S. privacy policy on April 30 to formalize data-sharing arrangements with advertisers and marketing partners, explicitly acknowledging that it receives purchase data from advertisers to measure ad effectiveness and shares user information with marketing partners for third-party targeting. The updated policy renames OpenAI's vendor disclosure category to include “marketing partners” and marks a shift from its prior stance that it would “never sell” user data, though an OpenAI spokesperson told Adweek that “nothing about our policy of not sharing people's conversations or other private user content with advertisers has changed” and that it shares only limited identifiers like cookie IDs or device IDs.
