Facebook Marketplace

Facebook Marketplace data can support Meta product improvement, personalization, ads, and AI-related experiences.

Meta documents privacy settings and data controls across Meta Products.

Meta can use activity that other businesses send to Meta to personalize Facebook and Instagram experiences and AI responses.

Users can limit this through the Activity from other businesses setting where the rollout is available.

Meta already uses off-platform activity for ads and is expanding related personalization to feeds and AI responses.

The Activity from other businesses control can stop this data from being used for ads, feeds, and AI-response personalization in supported regions.

Retention depends on account state, public/shared content, safety, legal duties, backups, and business records.

Meta provides access, transfer, deletion, and account-management tools.

Cross-product defaults and social sharing can make privacy outcomes difficult to reverse.

Users can manage privacy settings, ads, activity, sharing, and account deletion.
