Terms of Use
Last updated: 2026-09-23
The Japanese version of this page is the authoritative text. Other languages are provided for reference; if they differ, the Japanese version prevails.
These terms set out the conditions for using Putt Break Lab ("this site"), provided by GreenEngineer ("we", "us"). By using this site you are deemed to have agreed to these terms.
Article 1 (Scope)
These terms apply to the use of all content and tools provided by this site.
Article 2 (Status of the calculated results)
- The calculator on this site displays the result of a physical model based on the conditions you enter. It is not equipment for striking a ball, and it has no capability to measure a struck ball.
- The calculation rests on a number of simplifications, including treating the green as a single uniform plane at the average gradient. Real greens are affected by complex undulations, uneven turf, wind and temperature, so the calculated result will not match how the ball actually rolls.
- The results are reference information only. We make no warranty as to their accuracy, completeness or fitness for any particular purpose. Use them at your own risk, including for decisions in competition.

When using this site you must not:
