RESPONSIBLE ANALYSIS

In DrawIQ, “hot” and “cold” describe past frequency only. They do not mean a number is more or less likely in the next fair drawing.

DrawIQ is an educational randomness-audit tool. It does not sell tickets, recommend wagers, identify numbers that are due, or claim to predict winning numbers.

PRIVACY

DrawIQ has no account system, advertising, behavioral tracking, or third-party analytics. Validated drawing history and analysis settings are stored on the device. The app connects to public NY Open Data endpoints when a user requests a data refresh. Calendar access is optional and is used only to manage next-draw events in a calendar selected by the user.

DATA SOURCES

Mega Millions and Powerball history is provided by the New York State Gaming Commission through NY Open Data. Dataset coverage is not presented as the complete national history of either game.
