Edward Snowden wants to help protect your privacy with an app designed to transform any Android phone into a sensor for detecting intrusions.
According to Wired, the app, called Haven, is designed to be installed on a cheap Android burner, using the phone’s cameras, microphones and even accelerometers to monitor for any motion, sound or disturbance of the phone.
For example, you can leave the app running in your hotel room so it can capture photos and audio of anyone entering the room when you’re not there, such as the maid. It will then instantly send pictures and sound clips of those visitors to your primary phone. Haven even uses the phone’s light sensor to trigger an alert if the room goes dark, or if an unexpected flashlight flickers.
