Meta is using private AI chats for ads — what you can do

Meta is using users' interactions with its AI chatbot, Meta AI, to personalize ads and content across Facebook, Instagram, and WhatsApp as of December 2025. The change applies in nearly every region, with exceptions in the EU, the UK, and South Korea, where privacy regulations such as the EU's GDPR remain in place. The article says in-app ad preferences are limited and do not fully stop behavioral targeting, and it recommends steps such as turning off personalized ads, separating Meta accounts, and sending an opt-out request. It also promotes Proton's Lumo assistant as a privacy-first alternative.
