Tracking you across apps
You are agreeing to let Meta combine data from third-party partners about your offline and external online activity to tailor advertisements shown to you.
“We’ll use information that advertisers, businesses and other partners provide us about activity off the Meta Company Products that we have associated with you to personalize ads... whether or not you’re logged in or have an account”
What that means: Advertisers and partners can track your online behavior even when you are not logged into Meta, creating a detailed profile of your interests.
Meta tracks your activity on websites and apps outside of its own ecosystem using data from partners to build a profile of you for advertising purposes.
