Did or did not he mentioned about what happen to already analyzed data ?

What I meant is facebook actually create a kind of DNA per user by analyzing behavior.

If I choose to delete my history did it delete my DNA data too ?

And what about data analyzed by third-party which installed by one of my friend and have access to my data. Did this feature(delete) will target above problem too ?

My understanding is it will not going to be an easy task and if it actually delete all your data what happen to advertisement business ?
