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. By combining the array of sensors found in any smartphone, with the world’s most secure communications technologies, like Signal and Tor, Haven prevents the worst kind of people from silencing citizens without getting caught in the act.
Haven was developed through a collaboration between Freedom of the Press Foundation and Guardian Project. Prototype funding was generously provided by FPF, and donations to support continuing work can be contributed through their site.
Safety through Sensors
Haven only saves images and sound when triggered by motion or volume, and stores everything locally on the device. You can position the device’s camera to capture visible motion, or set your phone somewhere discreet to just listen for noises. Get secure notifications of intrusion events instantly, and access logs remotely or anytime later.
The following sensors are monitored for measurable change, and then recorded to an event log on the device:
- Accelerometer: Motion and vibration of phone
- Camera: Motion in the phone’s visible surroundings from front or back camera
- Microphone: Noises in the environment
- Light: Change in light from ambient light sensor
- Power: Detect device being unplugged or power loss/shutdown
NonFreeDep: The application depends on a non-free application (e.g. Google Maps) - i.e. it requires it to be installed on the device, but does not include it.
