Terms of service

Updated 5 November 2026. These terms describe use of Pushing Tin over Grafton, operated by Grafton Machine Shed.

Playing and learning

The service is an air traffic control game for play and learning. All aircraft, radio exchanges and airport systems are simulated. The game does not control or communicate with real aircraft or airport equipment.

In ChatGPT lessons, you give decisions through conversation and your tutor sends your instructions to the simulator. Watch is a read-only display. The separate browser workstation offers direct mouse and keyboard control. Tutor explanations and game outcomes are part of the learning experience; they are not a professional qualification.

Use of the service

You can play without a game account or signing up. A valid Watch link lets someone view the associated simulation, so share it only with people you want to invite. Do not disrupt the service, bypass access controls or attempt to access another player's private records. Follow the rules of the AI platform you use to connect.

Game records

Playing creates records of the exercise, information shown during the session, actions and outcomes. Lessons can also record answers and teaching text sent by your tutor. We retain game records indefinitely for internal AI training and do not publish them. Read the privacy policy for the information recorded, service providers, analytics and available controls. Avoid putting personal or sensitive information in learner answers or game instructions.

Availability

The simulator is being developed and may change. Capacity limits, maintenance, faults or connection loss can interrupt a game. A run may need to be restarted. Contact us about problems or questions at admin@grafton.ai.
