Disabling / Uninstalling FaceBook are good questions.
After the 14-day wait-period, I am FB free.
You may be free but I imagine they still keep all your data.
Did you download your Facebook file? I did before I deleted my account and finally looked at it the other night, I was blown away by all the information they had collected on me.
If you have Facebook on your phone, regardless if it is Android or IOS, if you don’t alter the permissions, the default is that they record every call and text sent or received, access to your address book, your camera and the the microphone in your phone. They record everything they can.
