Games built by Britt Poplin (aka ylempoint at ylem's ink) do not intentionally store or transmit your personal data although I use Unity and Google services. The games do store high score and game save information in the user preferences of the device that the game is loaded onto.

NOTE: The free version of the games do use Unity Ads and/or Google AdMob to serve ads. Stack and Bomb Free may allow third parties to collect Non-personal data through their own embedded technology in order to deliver ads to you via a unique cookie or similar technology for non-personally identifiable information.
