Response from developer

JustRenisfine, thank you for your constructive comments. Like you, we are concerned about data privacy. We do not collect/mine any data ourselves (except for game scores so they can be shown in Game Center, and crash logs to fix bugs), though our ad partner, Google, does. You can limit data collection by turning off tracking under Settings->Privacy & Security->Tracking on your device. We are two hobbyists who have spent hundreds of hours refining this little app over several years as a very part-time effort. It's quite surprising how much time it takes to develop a quality app. We thought ad revenue would help support further development for this app and other app ideas we have. Unlike most game apps, we took a very conservative approach to ads: The app only displays one ad after completing each game. We also limit ads to the most restrictive "general audience" level and block sensitive ad categories. It's no surprise then that our ad revenue has been very low. We cannot quit our day jobs just yet :) Since ads really haven't helped much, and with increasing privacy concerns these days (rightfully so), we will be removing ads completely in an upcoming update. Instead, the app will offer some limited level of daily play for free, and an in-app purchase for unlimited play. So please stay tuned and watch for updates. Again, we appreciate your comments and welcome any other feedback. And thank you for playing!
