If you were wondering what kind of data Facebook has on you, its just a click away. Facebook has a timeline of every post and comment you wrote from the very first day you started using it. It has every file you’ve sent or received.

The information Facebook and Google store about you is staggering. Facebook stores lists of what it thinks you might be interested in based off the things you’ve liked, searched or posted.

Facebook has a list of everyone you’ve previously said you were in a relationship with and a list of ad categories it has associated with your account.

It also stores data about every time you have logged in to Facebook, from where and on which device. And there’s more.

Facebook announced that in the coming weeks it will expand the data it allows users to download to include likes, reactions, search history, and location history.

This will also a new tool called Access Your Information, which allows users to more easily view and delete old posts, reactions, comments, and search history.
