Grattr was a weekend project to enable individuals to publicly identify with demographic characteristics -- your "Globally Recognized Attributes".

By attaching these attributes to email addresses, Grattr allows demographic analysis to be performed on any group of emails, including conference registrants, college applicants and company employees.

We don't keep anything except the attributes that you've made public. If the choices for attributes seem odd, it's because we've used the Bermuda 2010 census as our base. Please feel free to post in the comments any attributes that you would like to add or raise a PR to our repo: https://github.com/cactus-bm/grattr-webapp

Sign up is easy: https://app.grattr.org/

Attributes are publicly accessible via an API: https://bba96qwn33.execute-api.us-east-1.amazonaws.com/prod/attributes/{email}

Examples for myself and my co-founder James:
