Frequently Asked Questions

When does Sonar-X alert me?

When does Sonar-X alert me?

Sonar-X will only alert you if: 

You were in the same location as a user who was infected with the Coronavirus

You interacted with a user who was infected with the Coronavirus

Your social distance is violated by another user

What happens if I self-report a positive test?

What happens if I self-report a positive test?

Anyone who was in the same location as you or who interacted with you directly will be notified that they might have contracted the virus, and may need to be quarantined for 14 days.

Does Sonar-X really work without needing personal information?

Does Sonar-X really work without needing personal information?

Yes. Privacy and security are incredibly important to us, so every user is assigned a random user ID, data is saved exclusively on the user's device, and alerts occur strictly on a peer-to-peer level.

What does Sonar-X know about me?

What does Sonar-X know about me?

Sonar-X knows nothing about you. We only maintain location and individual interactions in order to maintain your safety. Your data is never associated with a name, phone number, or email address

What does Sonar-X use the microphone for?

What does Sonar-X use the microphone for?

Your devices microphone is only used for receiving ultrasonic tones. It will never record, save, or transmit any data.

What is Ultrasonic Technology?

What is Ultrasonic Technology?

Ultrasonic means it is outside of the audible range for both humans and animals. SONARAX has harnessed the power of ultrasonic waves to create ultrasonic technology which is able to accurately measure the distance between two points in real-time.

Is Sonarax's ultrasonic-based app is more secure and accurate than Apple/Google's API?

Is Sonarax's ultrasonic-based app is more secure and accurate than Apple/Google's API?

Sonar-X’s Ultrasonic technology, harnesses the power of sound waves which are the only connectivity medium that can be contained within a defined location. This empowers the ability to detect the precise location of an audio signal and verifies its precise physical presence. Other wireless data communication mediums such as WiFi or BT use radio waves (RF) that cannot be contained, and easily travel through walls, dividers, ceilings, and floors. As such, the Sonar-X application is able to trigger alerts for a very precise radius (around 10 feet) which is much more in-line with the recommended social distancing parameters set forth by the CDC, WHO, and others, and will, therefore, result in much more accurate alerts and fewer false positives.


Sonar-X is totally anonymous, asks for no personal information, and it is completely disconnected from your phone number and email account. Sonar-X users are assigned a random user ID in order to identify them in the future in the case of infection alerts. Additionally, ultrasonic connectivity doesn’t provide an access channel to your device, it’s used by the application exclusively to communicate with other users.


Bluetooth Low Energy (BLE) has a radius of around 30 feet, which is far larger than the radius recommended by every global health organization. Additionally, BLE is able to travel through walls, and has no ability to detect anything other than connected or not connected.


If BLE technology were to be deployed on a large scale for the purposes of Contact tracing, the result would be incredibly high levels of false positives.


In terms of privacy and security, Apple and Google’s solutions are based around your personal apple and google accounts. This creates an inherent issue of separating your data from your account, or hoping that a malicious 3rd party doesn’t do it. There are also inherent vulnerabilities from having an open BLE channel potentially providing an attacker with access to your device. While Google and Apple have said they’ve employed a number of different protocols to protect user privacy and security, Contact Tracing is only useful if it achieves a critical mass, and we already know that users are wary of the tech giants from the perspective of privacy.

Does the app work in the background? Or does it need to be opened?

Does the app work in the background? Or does it need to be opened?

The Sonar-X application only needs to be opened initially, and then it will work in the background until it is actively closed by the user. Since it does not rely on and additional connectivity (BT, BLE, GPS, WiFi, Data, etc…) it will also work just as well if the user is using battery-saving applications that reduce the device connectivity while not in use.

Sonar-X is able to scale, at any rate of growth with no adverse effects?

Sonar-X is able to scale, at any rate of growth with no adverse effects?

Since all user data is stored on the user’s device, and communication happens strictly on a peer-to-peer level, there’s no chance of servers being overrun or being knocked offline. Additionally, the platform requires absolutely no connectivity (Data, WiFi, GPS, etc…), so again, in terms of scale, there’s no real difference, from a technology standpoint, between 5 users or a million users.

Even if all of the one million users were in a single room (which would not be recommended due to social distancing concerns), every device with the Sonar-X application installed would be assigned a unique combination of ultrasonic tones. The software is then able to filter out and ignore any ultrasonic tones or ambient sound that does not correspond to the Sonar-X algorithm, and the application would still work just as well as it would with 2 people in a room.

Finally, since every interaction between users is saved locally on the user’s device, it’s also important to mention the efficiency in storage space. Each interaction takes up only 100 bytes, so again, if you have a million people in a room, all of those interactions would only use 500 megabytes of storage space.

What is Sonar-X’s strategy for mass adoption?

What is Sonar-X’s strategy for mass adoption?

Clearly there is a need for mass adoption of contact tracing in order to enable it to be effective. By some estimations, the critical mass would be somewhere around 60% of the population, which is around 80% of total smartphone users.

Sonar-X’s strategy to achieve mass adoption would be through a grassroots movement through our consumer and business applications. These applications allow business owners and individuals to protect themselves, their customers, and their clients by simply installing and activating the application. Once activating, the application will run in the background on their device and keep them safe throughout the day.

Another way to achieve this that has been discussed in the media would be through a governmental mandate. When hearing this, we recognized how concerned many people would be with regards to privacy and security, which is why we designed our application to be totally anonymous. Our hope is to achieve a level of mass adoption prior to a governmental requirement coming into effect.
