Key points: contact syncing is optional for finding friends using OpenAI services, ads may appear for Free and Go plan users while Plus, Pro, Enterprise, Business, and Education plans remain ad-free, ads are clearly labelled and do not influence ChatGPT responses, advertisers never see chats or personal details and only receive aggregated data like clicks or views, and age prediction helps provide safer experiences for younger users.
