But even if you aren’t an Android user, Facebook has an archive of data that it's been gathering about your interests. Thisincludes every like, comment, photo, etc., since you first started using Facebook.
This content is then used to target advertisements toward you.
Here's what you need to do to download that data:
Go to the drop down menu in the upper right hand corner.
Select “Download a copy of your Facebook data."
Click on the green button that says “Start My Archive”
Be aware that it is probably a massive file since it will likely contain years worth of data.
