Why GreenZone?

We developed GreenZone in accordance with our mission to change how people own and manage their digital identity and data. We are very concerned with the apps now being deployed by Governments and companies globally. They embed personal tracking mechanisms that may never be removed. Assurances made today respecting personal data may not survive when government officials change. GreenZone lets individuals periodically self-report any symptoms they may have from volunteered locations. Our app measures how many people say that they are well in their local community. Our goal is simply to reduce the fear and anxiety arising from not actually knowing if anyone has symptoms in a specific apartment building, office, factory or neighborhood.

Why GreenZone ?

GreenZone is developed by Human Rights Experts and Technology Professionals for the Bluenumber Foundation, a registered charity in New York State (NYS Office of the Attorney General) and recognized by the IRS as tax-exempt under Internal Revenue Code (IRC) Section 501(3)(c).

Our Foundation’s mission to enable you to own and manage your digital identity and data. We are very concerned with the apps now being deployed by Governments and companies globally. These embed personal tracking mechanisms that may never be removed. Even if assurances are made today to respect your personal data these may not survive when thecurrent government officials change.

Green Zone crowdsources data for you to support and revive activity in your local area.

Frequently Asked Questions

No, it is not. GreenZone does not use Bluetooth or ‘handshake’ with any other devices you may be near to. It does not track your location or map where you have been over any period of time.

GreenZone allows you to give ‘safety and comfort’reviews to places, facilities and businesses in local area. If you want to give a rating the app will ask for a GPS reading of where you are to present a list of all places, facilities and businesses within 100m of your location. Your GPS allows an accurate local list to be presented to you. Your GPS data is not retained or stored. If you make a review about the place you choose from the list, the review will be tagged with the GPS of the place (not you).

You can only review places within 100m of your actual location. The review you give must be based on what safety measures you actually see being taken (or not) at those places.

You own your own data. Always.

Your data is stored in the Bluenumber Foundation Cloud hosted by Amazon Web Services (AWS). Your data is kept for 21 days, then it is overwritten – i.e. the report you submit on Day 22 will erase and replace the data from Day 1. There will be no record kept of that data.

If you wish to keep a copy of your own data you can download it into your personal cloud service (for example Google Drive, iCloud, Dropbox, etc.). This feature will be available within 14 days.

GreenZone gathers (i) the number of your mobile device to send an OTP; (ii) the GPS location of ‘pins’ you select around which you choose to do reviews; (iii) survey questions of your observations at places you choose to review; and (v) the GPS location of the place, facility or businessyou review.

NB – GreenZone does not ask you for your name or any personal identification. GreenZone does not track your movements or who you have come into contact with.GreenZoneonly works if you choose to tag yourself to a place, facility or business already listedin the Google Maps.

GreenZone uses a star rating to show what safety measures place, facility or business has taken to ensure your comfort in being there. GreenZone measures seven (7) variables: Social Distance, Signs, Spacing, Surfaces, PPE (for Staff), PPE (of Visitors) and Disinfecting. A 1-star rating means only ‘Minimum and basic requirements’ (Social Distance and Signs) are in place. 2-stars means the business has spacing and disinfected surfaces to assure customers the physical environment offers free movement and hygiene. 3-stars means all staff wear protection equipment such as masks (always) and gloves (for food service). A place gets 4-stars if it influencesvisitors to adopt good practices by requiring that they wear masks to come in. a 5-star rating is given if that place continuously disinfects equipment that customers or clients must use such as trolleys (in a supermarket) or computers (in an office).

Your data is yours. You can share it if you wish according to features or other apps you may have on your device. GreenZone allows you to share data for one day (‘today’) or for a 14-day period. Please do not share your data unless you know and trust those you are sharing with!

Please don’t. GreenZone relies on your honesty. As much as you want to be safe, so do those around and near you. An honest report will help a business get better if they are lacking in some areas..GreenZone shows reviews dynamically – all reports reset after 3 days so visitors and customers can be confident of the current measures being taken by places.
