We collect information about the ads on the Netflix service that you view or interact with, device information (such as resettable device identifiers), IP addresses, and information provided by Advertising Companies (such as information about your likely interests they have collected or inferred from your visits to other websites and apps). We use this information to support Advertisements (including behavioral advertisements in accordance with your preferences).
This means your activity outside of Netflix — on completely unrelated websites — can influence the ads you see on Netflix, raising significant cross-context tracking concerns.
Netflix collects a wide range of personal data including viewing history, device identifiers, payment information, and behavioral data inferred from your activity on third-party websites and apps, particularly for users on the ad-supported plan. Users have rights to access, correct, delete, and export their data, and can control certain advertising preferences, but the policy's vague retention language and broad third-party data sharing create residual privacy risk. You can manage your advertising and data preferences by visiting your Netflix account settings at netflix.com and navigating to 'Privacy and Data Settings'.
