Data transferred to the US may be subject to US government surveillance laws that do not provide the same protections as EU law, and invalidation of transfer mechanisms — as has occurred previously — could disrupt services and expose Meta to regulatory penalties.
Meta's policy authorizes collection of an exceptionally broad range of personal data — including location, biometric features, financial information, browsing history across third-party sites, and sensitive inferences about health and political views — primarily to serve targeted advertising. Non-users who have never created a Meta account are also subject to data collection when they visit sites using Meta's tracking tools such as the Meta Pixel. You can review and limit off-platform tracking by visiting Facebook Settings > Your Facebook Information > Off-Facebook Activity and clearing or restricting that data.
