You must provide users with clear and prominent notice, and obtain their explicit consent, before collecting, using, or sharing their data in ways that are not reasonably expected by users based on the context in which the data was originally shared.
This provision requires genuine, informed consent from users before their Facebook data is used in new or unexpected ways, which is a meaningful protection against covert data repurposing.
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.
