This is one of the most direct protections for Facebook users — it means that in theory, apps using Facebook login cannot monetize your data by selling it to data brokers or advertisers.
Meta's Platform Terms directly affect consumers because they determine what third-party apps and developers can do with personal data obtained from Facebook or Instagram, including profile information, friend lists, and activity data. The terms prohibit developers from selling platform data or using it for surveillance, but enforcement depends on developer compliance rather than Meta directly protecting users. You can review and remove third-party apps that have access to your Facebook account by visiting Facebook Settings, then 'Apps and Websites', to revoke permissions for any app you no longer trust or use.
