Facebook today revealed that the Cambridge Analytica data leak affected 87 million people, most of whom reside in the US. Previously, it was believed that the leak impacted 50 million.

On Monday, April 9, Facebook plans to start adding a link to the top of News Feed showing a list of the apps and websites connected to your account, and the data those services have access to. From that link, you'll be able to remove any apps you no longer want connected to your account (something you can already do via App Settings).

"As part of this process we will also tell people if their information may have been improperly shared with Cambridge Analytica," Facebook Chief Technology Officer Mike Schroepfer wrote in a blog post.

Facebook also today proposed updates to its terms of service and data policy in an effort to make them easier to understand. Users can review the updated documents and provide their feedback for the next seven days. Once finalized, Facebook will publish the documents and ask users to agree to them.

"These updates are about making things clearer," Facebook Chief Privacy Officer Erin Egan and Deputy General Counsel Ashlie Beringer wrote in a blog post. "We're not asking for new rights to collect, use or share your data on Facebook. We're also not changing any of the privacy choices you've made in the past.

Meanwhile, Facebook CEO Mark Zuckerberg is headed to Capitol Hill next week to testify before the House Energy and Commerce Committee about the data leak.
