This app is intended for entertainment purposes only and does not provide true date of death functionality.
The guess of your date of death is done using some rough estimates based on minimum data provided by the user via Facebook. You should definitely not take this info too seriously and data shown is not collected anywhere remotely.
This version of the app uses the following data to guess your date of death:
1. Your birthday *
2. The country youre living in *
3. Life expectancy for countries data provided at http://en.wikipedia.org/wiki/List_of_countries_by_life_expectancy. Recent data from 2012 by the CIA are used.
* Facebook login is required, we ask for the minimum profile permissions just to grab your birthday and the country you live.
