Most “free” kids’ apps aren’t. They’re free until the coins run out, and then they’re a conversation at bedtime about a membership.
Nobel Games makes desktop games for ages 5–11 with zero ads, zero in-app purchases and zero tracking. You pay $14.99 once, it installs on your computer, and that’s the last time money or data comes up.
Why we can say this and most apps can’t: we don’t run a server. There is no analytics pipeline, no ad SDK, no account system. You can verify it in thirty seconds with Little Snitch or any network monitor — launch the game, play a round, watch nothing happen.
