OpenAI has revised its privacy policy to include the sharing of limited user information with third-party advertisers to promote services like ChatGPT and Codex. This update allows OpenAI to track user interactions and measure the effectiveness of its advertising efforts. However, the company assures that user conversations will remain private and not shared with marketing partners. Users were notified of this change via email, and it currently applies to those in the United States. To opt out of ad tracking, users can navigate to the settings in the web version of ChatGPT and disable marketing tracking. The policy clarifies that OpenAI will only share identifiers such as cookie IDs or device IDs, not personal conversations. The move aligns with industry trends, as competitors like Google are also exploring ad placements in their AI products.
