Haven: Keep Watch

HAVEN

Haven is for people who need a way to protect their personal spaces and possessions without compromising their own privacy. It is an Android application that leverages on-device sensors to provide monitoring and protection of physical spaces. Haven turns any Android phone into a motion, sound, vibration and light detector, watching for unexpected guests and unwanted intruders. We designed Haven for investigative journalists, human rights defenders, and people at risk of forced disappearance to create a new kind of herd immunity.

StalkScan

StalkScan is a tool that shows all public information for a given Facebook profile. 
It doesn't involve any hack or hacking, it just displays public info from Facebook's official graph search.
Please be aware that results depend on privacy settings: if information is set to 'friends only' it will only show up for Facebook friends.
The website itself is ment for a personal privacy checkup, not for stalking.
