Optional

Help train Sensei.

Sensei learns from games. If you turn this on, matches you finish here are sent to us and used to make it play better. It is off unless you switch it on, and you can switch it off again at any time.

What gets sent

  • The tiles dealt and every move made, for each hand you finish.
  • What the AI's model calculated on each turn, so we can tell a bad model from a bad browser.
  • Which browser engine ran the model, and which version of the AI played.

What does not

  • No name, no email, no account — there isn't one to have.
  • Nothing from your camera. That is the app, and it never leaves your phone.
  • Nothing at all until you turn this on, and nothing from unfinished matches.
