Developed and published by Arj Global Ltd, a UK software development company.
BattleBrain uses AI technology to help validate and check some of the facts and comparisons used in the game.
This AI-powered validation uses Anthropic’s Claude platform and API.
BattleBrain is designed for fun and general discovery.
BattleBrain is designed so children can play without entering their name, email address, phone number, school or other unnecessary personal information.
Game preferences and scores, such as Your Best, may be stored locally on the player’s device.
Like any online service, our hosting and online providers need to process basic technical request information (such as IP address and device type) to deliver the game and keep it secure.
BattleBrain is currently free to play. It started as a fun father-and-son project and we want children and families to enjoy it.
Running BattleBrain involves ongoing costs such as hosting, infrastructure, AI services and platform fees. If BattleBrain grows significantly, we may introduce optional paid features or pricing in the future to help cover the cost of running and improving it. Any future pricing will be clearly communicated before a user is charged.
