You must not use data obtained from us to provide tools that are used for surveillance, including but not limited to, providing tools to track, monitor, or profile individuals based on their online activity.
This clause protects users from having their Facebook data turned into a surveillance instrument — for example, it prohibits building tools that track activists, journalists, or individuals based on their Facebook activity.
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.
