常见问题

Are teams truly balanced?

The list is shuffled with a Fisher-Yates algorithm using crypto.getRandomValues(), then distributed round-robin — teams differ by at most one member.

Does my data leave my device?

No. The entire operation runs in your browser. Names are never sent to a server.

Does it work on mobile?

Yes — the layout adapts for mobile with large touch targets and readable results.
