Your personal behavior, interests, location data, and social connections are continuously analyzed by Meta's systems to build an advertising profile that is the commercial engine of the entire platform.
Meta's Terms of Service grant the company an extremely broad license to use everything you post — photos, videos, text — for commercial purposes including advertising, and this license persists even if you delete content that others have already reshared. Meta retains the right to suspend or remove your account, restrict content visibility, and modify these terms with as little as 30 days' notice, meaning the rules governing your account can change materially over time. You can review and adjust your advertising data preferences by navigating to Facebook Settings > Ads, and EU/UK users can exercise additional rights including data access, deletion, and objection to processing via the Facebook Privacy Center.
