One graph, two sides.
Clubs, coaches, facilities, leagues, and tournament directors run their businesses in Duna. Players and parents use Duna to learn, find, book, compete, connect, and carry their history. Every verified match makes the network more useful; every player makes the operators stronger.
Built for the shape of this sport.
Doubles ratings, partner claims, work teams, weather holds, purse payouts, public-court pickup, minors safety, and offline scoring are not add-ons. They are the architecture.
The operating system for sand. The network for everyone who plays on it.
