Snowden's new app protects you from kidnappers. Or maids

Finally, an app to protect you from "evil maid attacks."

Edward Snowden, the whistleblower who exposed National Security Agency spying on American phones, has a new Android app to protect your personal security too. It's designed to be a "'safe room' in your pocket, or way to defeat 'evil maid' attacks," according to its designers. 

Haven, an app made by Freedom of the Press Foundation (Snowden is president and a board member of the group) and the Guardian Project, turns any Android phone into a "motion, sound, vibration and light detector, watching for unexpected guests and unwanted intruders." 

The app works by saving images and sound when a motion or noise triggers it to turn on, essentially. Then it stores everything it captures on the device. It will also send secure notifications of intrusions as soon as they occur, and it allows you to access logs remotely anytime.

"We designed Haven for investigative journalists, human rights defenders, and people at risk of forced disappearance," the makers said on the app's Github listing. "Haven prevents the worst kind of people from silencing citizens without getting caught in the act."
