Facebook unveils long-promised tool to limit what data it receives from third-party apps and websites. But will not allow users to delete info.
Facebook unveiled its long-awaited feature allowing users to limit businesses, apps, and other groups that collect data about them on the Web and pass that information to the tech giant — a move that may disappoint people who thought they would be able to delete that information from Facebook in full. The social media giant said the new tools to control “Off-Facebook Activity” are designed to “shed more light” on a form of online tracking — around shopping habits, web-browsing histories and other activities — that determines some of the ads people see on Facebook.
