Power Up Castle
Online chess platform for kids with a focus on privacy and safety.
At Power Up Castle, you knock on a moonlit door and wait for torches to answer before your first move. Lanterns glow, a wind chime hangs by the gate, and the Hall of Champions sits blank, waiting for a name.

How it was built
BUILT BY A DAD FOR HIS DAUGHTER Power Up Castle started because Ada wanted to play chess online with her friends — but every "chess for kids" site I found leaked personal info, public chat, ads, or all three. So I built the castle she'd actually want to live in. Every feature you see here is something Ada (or one of her test players) asked for at the kitchen table.
