FEATURE 01At-a-Glance Design
Disaster prevention and weather information are integrated with an easy-to-understand map interface, so you can find the information you need at a glance. On the home screen, information is automatically sorted according to importance.
-
FEATURE 02Useful for Daily Activities
Check the rain cloud radar and weather forecasts, as well as other useful daily information such as current temperature, wind speed and direction and volcanic ashfall forecasts.
-
FEATURE 03Unobtrusive by Nature
We won't send unnecessary push notifications such as advertisements or announcements. There are no advertisements or pop-ups in the app that interfere with operation. We only provide you with the information you need for disaster prevention. Learn more about our decision on the Supporters' Club page.
-
FEATURE 04Real-Time Updates
Real-time earthquake alerts that display the expected seismic intensity at your current location and the number of seconds until arrival, seismic intensity and tsunami information that is automatically updated while the screen is open, and lightning strike information that is updated every minute. Other frequently updated information is also immediately reflected.
Push Notifications for Important Information
Critical Alerts, Normal Notifications or Silent Notifications will be issued depending on the user’s location, the type of disaster information, and the level of urgency. If there is an imminent danger and the user must act quickly, like in the case of an Earthquake Early Warning or Tsunami Warning, Critical Alerts get the user’s attention by breaking through the phone’s Silent/Do Not Disturb/Focus modes and sounding at maximum volume.
※ Critical Alerts can be disabled at any time; [iOS] Settings > Notifications > Critical Alerts, or [Android] Settings > Notifications > Silent Mode Exception (Android 9.0 or later). When disabled, Critical Alerts will be treated as normal notifications.

Disaster Awareness Series
We created this series of commercials as a message of 'self-discipline' to ourselves. Japan is a country that experiences frequent natural disasters, so it's important that the message we wish to convey with this series, is that "so long as you're here, be prepared".

Introducing the NERV Disaster Response Vehicle Reflection means thinking about the future
-
The NERV Disaster Response Vehicle is a PHEV, a hybrid vehicle with power generation capabilities, that can be deployed to ensure that our information distribution activities can continue in the event of an accident or disaster that results in a prolonged power outage.
When we imagined what would happen if a blackout like the one caused by the 2018 Hokkaido Eastern Iburi earthquake were to occur in Tokyo, we could see ourselves helplessly regretting our lack of preparedness. As long as such events are possible, we want to be as prepared as possible.

In the aftermath of the Great East Japan Earthquake, when everything came to a standstill, the availability of information was the difference between life and death for many people. While some lives were saved by the information they had beforehand, others may have lost their lives because of it.
There must have been many lives that could have been saved if the information had been available immediately afterwards.
We, modern people, trust our lives to information.
Without information, action is delayed.
But when a disaster of that magnitude strikes, you have to use your intuition and act on your own before waiting for information.

Privacy
The NERV Disaster Prevention app prioritises user privacy and security. It only collects necessary data for functionality. Precise location data is processed entirely on-device for disaster prevention purposes and is never shared externally. Location information for push notifications is converted to an area code (like a post code) that is stored on the device. No location history is stored, ensuring your movements cannot be tracked.
-
Credibility
Certified for operational systems, equipment and technical suitability, we provide our Earthquake Early Warning service as a licensed operator for forecasting services (earthquake ground-motion), as provided by the Director General of the Japan Meteorological Agency (JMA). The Risk Distribution notification service was jointly developed with the JMA as a cooperating operator. Other disaster prevention and weather information is processed independently from JMA data.
-
System Reliability
Our information processing system is connected via a dedicated line to the Japan Meteorological Agency's main office in Tokyo, and the Meteorological Service Support Centre at the Osaka District Meteorological Observatory. This system is geographically redundant with multiple data centres based in Tokyo and Osaka, and is designed to be able to continue working in the event of a major disaster.

Privacy ※1
Acquired location information and registered area information is used only for displaying disaster prevention information and sending push notifications. Location information sent from the application to the server is converted into an area code or mesh code in advance, within the application (client side), and only those codes are sent over the internet. In other words, the user’s detailed location coordinates never leave your device.
-
Battery Consumption ※2
If the app's location setting is set to "Always Allow," the app will periodically retrieve your location in the background. This should have very little impact on your battery life. Also, when "Low Power Mode" is enabled, the app will not update your location in order to reduce power consumption.

※1. Gehirn Inc. is first and foremost an information security company. The security and privacy of our users is our highest priority. We take great care not to collect excessive amounts of information about our users through this application.
Acquired location and registered location information is used only for displaying disaster prevention information, and for sending push notifications. The location information that's sent from the app to the server is first converted to an area code. An area code is roughly equivalent to a zip code. Only that code is sent to the server, meaning the user's exact location is never sent to the server.
For example, if you were located in "Chiyoda-ku, Tokyo", it will be converted to a code that is used by everyone in Chiyoda-ku, so no one will ever be able to trace your exact location back to you. Additionally, the server doesn't store past area codes, so your movements cannot be tracked.
All data sent over the internet is first encrypted, and all data stored in the server's database is encrypted before being stored. If you ever set your location permissions to "Do Not Allow" or "Allow Only While Using", the registration information will be deleted from the server. Additionally, if the user ever uninstalls the app, the registration information will automatically be deleted from the server roughly one month after the app last tried to communicate with the server.
※2. In order to receive notifications about disasters related to your current location; [iOS] Set Location permissions to "Always Allow" and enable "Background App Refresh". [Android] Set Location permissions to "Always Allow".
When you set the app's location permissions to "Always Allow", the app will periodically retrieve your location in the background. This doesn't happen often, so the battery usage impact is negligible. Additionally, if "Low Power Mode" is enabled, the app will not update your location in the background in order to save power.
