A game they build in, with the park hours built in.

Nobody talks to your kid.

Park Hours.

You set the daily time. The current ride always finishes, then the park closes.

Building, not scrolling.

Every minute is spent making something and then riding it.

Built with a kid, not in a boardroom.

It started with one kid asking for a loop.

Park Hours

You set the daily time in the grown-up dashboard. There's no countdown clock on screen while your kid plays — when time is up the current ride finishes, the coaster saves, and the park closes for the day. The limit comes from the game, not from you.

Questions

Is there chat?: No. There is no chat, no comments, and no friend discovery.
Can my kid talk to strangers?: No. Sharing is an outbound link only, and shared pages show no child identity.
What data do you collect?: The minimum needed to run your account: a parent email and the coasters your kid builds. No ad tracking, no data sale. Kid profiles are a nickname and a train color.
Does it work on iPad?: Yes — it runs in the browser. No download, no app store.
Can I cancel?: Anytime. Access continues until the end of the paid month.
Is it educational?: It's play. Kids pick up a lot of physics intuition, but we don't sell it as school.

Built with a kid, not in a boardroom.

CoasterLab didn't start as a business plan. It started with a question from a kid: can I build my own roller coaster and then ride it? So we built one. Then the kid wanted a loop. Then a launch. Then a faster launch.

That's still how CoasterLab gets made. A kid asks for something, we build it, and we watch whether it makes them yell.
