Facebook is rolling out Activity Log to mobile, a privacy feature that was only available in your computer-bound account. The log lets users monitor and control what shows up on their Timelines.
This means you won't have to wait to delete automatically generated "stories" such as the dozen times you listened to "Call Me Maybe" on Spotify.
If you have the new log, you can find it on your Timeline profile page in the listing that includes About, Photos and Friends. (If not, be patient. You should see it soon.) From the mobile activity log, you can see the privacy setting associated with each action you took on the social network or with a Facebook-connected app. You can delete any of the activities in the list by clicking on the circle next to an item.
The mobile log is a stripped down version of what you'll find on your desktop. Located under your Timeline cover photo, the Activity Log lets you change each activity's privacy settings, rather than just delete items. Only you can see your Activity Log.
