SAN FRANCISCO — Facebook has built an extensive network of tracking technology outside of its core social network to bolster its targeted advertising business. That has allowed the company to collect information about its users’ browsing habits, even when they were not using the social network.

On Tuesday, Facebook said it was changing its practices related to that data — kind of.

The company introduced a new tool that lets people better see and control the information that Facebook has gathered about their browsing habits outside the social network.

The tool, Off-Facebook Activity, allows users to view the hundreds of sites and apps that share data and customer information with Facebook. They can disconnect the data from their account if they want.

“This is another way to give people more transparency and control on Facebook,” the company said in a blog post. It added that people generally had more than 80 apps on their phones and used about half of them every month, making it difficult to know which ones had collected personal information and how the data was being used.
