As the article mentions, there appears to be only a small number of people who would need and benefit from this"Haven" app, but these few people could possibly avoid some serious threats by using the app. This app brings to mind the more than a few scenes from movies and tv where someone looks at another persons phone for pictures, texts, etc. in order to confirm suspicions about the phone owners activities, and this app may come to play in such situations for better or for worse. As also mentioned in the article it could help people who are victims of domestic violence. Seems to me terrorists could also use it, as well as Putin's enemies.
