Meta is set to update its privacy policies to start using users’ interactions with its AI tools to personalize ads on Facebook and Instagram.
Starting December 16, 2025, conversations with Meta AI – whether voice or text – will influence the ads and content that users see in their feeds. This change aims to provide more relevant ads based on users’ real-time interests expressed during AI chats.
Meta AI Ad Targeting 2025: How Meta’s New Ad Targeting Works

- Meta AI chat data will add to existing data like likes, follows, and clicks to better understand user preferences.
- If users talk about a topic, such as hiking, Meta may show related content or ads for hiking gear and groups.
- Sensitive topics like religion, health, sexual orientation, or politics won’t be used for ad targeting.
- Users in the UK, EU, and South Korea won’t experience this change initially due to local privacy laws.
- The update is announced via in-app notifications and emails starting October 7, 2025.
- There is no opt-out option; users must accept new terms to continue using Meta AI features.
- This change helps Meta monetize its expensive AI services through improved ad revenue.
