 # About Haven
 
-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.

 ## 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 the logs remotely or anytime later.

 ## Why no iPhone Support?
 
-While we hope to support a version of Haven that runs directly on iOS devices in the future, iPhone users can still benefit from Haven today. You can purchase an inexpensive Android phone for less than $100, and use that as your "Haven Device", that you leave behind, while you keep your iPhone with you. If you run Signal on your iPhone, you can configure Haven on Android to send encrypted notifications, with photos and audio, directly to you. If you enable the "Tor Onion Service" feature in Haven (requires installing "Orbot" app as well), you can remotely access all Haven log data from your iPhone, using the Onion Browser app.

 ## Usage
 
-Haven is meant to provide an easy onboarding experience, that walks users through configuring the sensors on their device to best detect intrusions into their environment.  (The current implementation has some of this implemented, but we are looking to improve this user experience dramatically.)

 ### Main view
 
-Application's main view allows the user to select which sensors to use along with their corresponding levels of sensitivity. A security code must be provided, which will be needed later to disable monitoring. A phone number can be set, to which a message will be sent if any of the sensors is triggered.
