On Three

Who runs this

On Three is run by DOPPO, a small company in Tochigi, Japan.

What we keep

  • The room code, the two names you enter, the questions you played, your answers and the results.
  • Rooms are deleted 30 days after they are created. No sign-up, no email, no location.
  • Your list of past games stays on your own device.

House rules

  • Don't put anything private in an answer, like a full name or address.
  • No answers meant to hurt someone, and no one else's personal details.
  • The matching is an automatic guess that forgives spelling and spacing. You two get the final say.
  • The service may change or stop without notice.

Paid unlock

  • Unlocking every topic costs US$4.99, charged once by card through Stripe. There is no subscription.
  • It works on the device you bought it on, and in any room you are in. Your purchase code moves it to another device.
  • Purchases are not refundable, but if something on our side kept it from working, write to support@kampetimer.com.
