Privacy Policy & Terms of Conditions


Thank you very much for using the “HUSH CITY” App. 

Your privacy is important to us. Please review this Privacy Policy carefully. 

This Privacy Policy informs users as to how their information will be collected, stored, disclosed, used and shared by Dr. Antonella Radicchi, in her capacity of inventor of the “HUSH CITY” App.

By pressing “Accept” you agree to our Privacy Policy and Terms and Conditions to use the App.

1. Introduction 

With this app, you are an active part of worldwide research to map quietness in cities. 

Our cities have become increasingly noisier by the hour. Only in Europe, over 125 million people are affected by noise pollution from traffic every year, and apparently, quietness is becoming a luxury available only to a few of us. By using this mobile app, you will contribute to making quietness available for all those who appreciate it.

This app will help you map and find the quiet spots in your neighbourhood where you can relax, enjoy time with your kids or simply have a peaceful conversation.  Enjoy slowing down!

Additionally, this app will inform you about noise pollution, our need for quietness and the “open source soundscape” approach. 

The information was provided in the frame of the research projects “Beyond the Noise: Open Source Soundscapes” and “Hush City Mobile Lab”, which were developed by Dr. Antonella Radicchi, in her capacity of inventor of the App. More information can be found in the info part of this app and at www.opensourcesoundscapes.org.

Please be informed that this Privacy Policy does not apply to the practices of third parties that we do not own or control, including but not limited to the hosting provider  Host Europe GmbH based in Welserstr. 14, 51149 Köln. VAT (ID: DE187370678, Commercial register number: HRB 28495, Website: https://www.hosteurope.de/).

The information collected will be used to compile worldwide maps of the quietness of our cities, which is the goal of this citizen science project.

2. What Information do we collect and how we use it

2.1 Personal Identifiable Information

Your personally identifiable information, including but not limited to, name and email address, may be required to start and run the App.

You acknowledge that this information may be personal to you, and by providing them, you allow us to identify you and therefore you may not be anonymous. The Personal Information we gather enables our system to generate a personal and unique user-ID, which will be needed to use the App.

Personal Information (including the IP addresses) will never be published and will only be accessible to the system administrator.

2.2 Location data and time periods

For the measurements and for compiling the maps on quietness, your precise location is needed. We use various technologies to determine your location, including IP address, GPS, and other sensors that may, for example, provide us with information about devices on Wi-Fi access points and on cell towers nearby.

The location data collected will be used for the survey as specified in the above section 1. “Introduction”, since scientists need to know both your location and the time at which you made the survey. Thus, this app needs to access your GPS to transmit the exact location of your survey.

The collected survey will be part of the citizen science project “Hush City”  (www.opensourcesoundscapes.org).  

The collected survey be stored with a randomly generated, anonymous ID number into the host provider HostEurope  (https://www.hosteurope.de/) and made available anonymously on the Internet and through publications in international journals and public presentations at conferences, symposia, and dissemination events in general. In this latter event, while we can guarantee that the collected surveys will be made available anonymously, we cannot foresee how and where such surveys will be disclosed.

2.3 Email communications

We may occasionally send you email and other communications. In particular, we may use your contact information and send you an email if we notice something peculiar about your measurements.

Please note that you could always opt out of receiving our communications by sending an email to the following address: info@opensourcesoundscapes.org.

2.4 Other Information Collected 

We may collect non-personal identifiable information when you use our App, including your urban soundscapes’ audio records and pictures, and answers to the surveys, which could be made public exclusively anonymously and for research purposes.

However, while we can guarantee that we will not disclose the user identity, we can not guarantee, despite our effort to control as much as we can the data uploaded, that the data (pictures, audio records and so on) uploaded by the users do not infringe any third parties rights.

Therefore, “HUSH CITY” App will not be liable for any data uploaded by users.
