Where do the questions come from?  Where do the answers go?

The questions and answers come from and are sent to an Azure service in the Cloud.

How are my answers stored?

Your specific answer is not stored.  Rather a tally is kept for each contender.  Your answer is added to the total people who favored your chosen contender by region and gender.

How is my region determined?

Your phone is configured for a certain language and country.  The Cloud service uses your country to look up the containing region.

Why do I have to specify my gender?

You do not have to specify your gender; however, you cannot see how people judged by gender unless you do.
