The NERV Disaster Prevention App is a smartphone service that provides users with real-time earthquake, tsunami, volcanic eruption, and emergency warnings, as well as weather-related disaster prevention information. The app utilizes proprietary technology to deliver the fastest information distribution in Japan by receiving data directly from the Japan Meteorological Agency. Users can access a wide range of disaster prevention information, including weather forecasts, earthquake alerts, tsunami warnings, and landslide information. The app also features a map that allows users to zoom in on their location or view the entire country to see cloud cover, typhoon forecast areas, and earthquake intensity. The app aims to provide users with the most relevant and timely disaster information. The home screen displays the latest information based on the user's location, ensuring that they have the most important updates at their fingertips. Push notifications are sent out based on the device's location and the urgency of the information. For critical situations, such as imminent danger or time-sensitive disasters, a 'Critical Alert' is sent to alert the user, even if the device is in silent or do not disturb mode. The app also features a barrier-free design, with color schemes and fonts that are accessible to people with color blindness and easy to read for all users. To support the development and operational costs of the app, the NERV Disaster Prevention App offers a voluntary membership scheme called the Supporters' Club. Users can contribute to the app's development by becoming a member and paying a monthly fee. The app prioritizes user privacy and takes precautions to collect minimal information. The exact location of users is never known, as all location information is converted to an area code. The server does not store past area codes, ensuring that user movements cannot be tracked. More information about privacy can be found on the app's website.
