In November, the groups teamed up with the Colombian activism group Movilizatorio to conduct a trial with social justice activists—a group that's been the target of dozens of assassinations over the last year, in the fallout of tense negotiations between guerrilla groups and the country's government.
Movilizatorio founder Juliana Uribe Villegas says the app provided a key reassurance that month, for a group of 60 testers, that government or criminals agents weren't breaking into their homes to plant surveillance equipment or, far worse, to kidnap or physically harm them.
Of course, any device that takes pictures and records audio clips in your home or office and sends them over the internet might sound more like an intolerable privacy violation than a security measure, especially for someone as privacy-sensitive as Snowden, who hasn't even carried a mobile phone since he first became a fugitive from the US government in But Haven takes some serious measures to prevent its surveillance mechanisms from being turned against a phone's owner. It integrates the encrypted messaging app Signal, so that every alert, photo, and audio clip it sends to the user is end-to-end encrypted.
As another safeguard, users can also configure Haven to work with the Android app Orbot, which has an option to turn your phone into a so-called Tor Onion Service —essentially, a server on the darknet. That means the Haven phone's event log can be accessed remotely from your desktop or another phone, but only over Tor's near-untraceable connection.
In theory, that means no eavesdropper can break in to access those audio and photo snapshots of your sensitive spaces. He notes that despite his personal avoidance of carrying a smartphone, even he has used Haven in hotel rooms while traveling and at home, albeit only with some additional precautions that he declined to fully detail.
In WIRED's initial tests of Haven's beta version, the app successfully detected and alerted us to any attempts to approach a laptop on an office desk, reliably sending photos of would-be evil maids over Signal. If anything, the app was too sensitive to saboteurs; it picked up and alerted us to every stray office noise. The app's accelerometer detection was so hair-triggered that even leaving the phone on top of a computer with a moving fan inside created hundreds of alerts.
You can set thresholds for the audio, but it was tricky choosing a level that wouldn't trigger false positives. Freitas says the developers are still working on fine-tuning those controls, but that users may have to experiment. Snowden acknowledges that Haven can't stop an intruder bent on physically harming someone.
But by simply detecting and recording their presence, it might just make them think about the consequences of that intrusion's documentation, and give victims a significant tool they haven't had before.

We designed Haven for investigative journalists, human rights defenders and people at risk of forced disappearance to create a new kind of herd immunity. View our full Haven App Overview presentation for more about the origins and goals of the project. We are announcing Haven today, as an open-source project, along with a public beta release of the app. We are looking for contributors who understand that physical security is as important as digital, and who have an understanding and compassion for the kind of threats faced by the users and communities we want to support.
We also think it is cool, cutting-edge and making use of encrypted messaging and onion routing in whole new ways. We believe Haven points the way to a more sophisticated approach to securing communication within networks of things and home automation system. Haven was developed through a collaboration between Freedom of the Press Foundation and Guardian Project. Haven only records when triggered by sound and motion and stores everything locally on the device.
Receive secure notifications of intrusion events instantly or access logs remotely later. The following sensors are monitored for a measurable change, and then recorded to an event log on the device:. The application can be built using Android Studio and Gradle. It relies on a number of third-party dependencies, all of which are free, open-source, and listed at the end of this document. If you are an Android developer, you can learn more about how you can make use of F-Droid in your development workflow, for nightly builds, testing, reproducibility and more here: F-Droid Documentation.
