Terms

Use OBO to learn, explore and write about physics. Do not use it to break the law or to interfere with anyone else's use of it.

Your account is yours to keep or close whenever you like. Accounts used to attack the service or other people can be closed without notice.

Simulations are teaching and exploration tools. They are built carefully and cite their sources, but they are not a substitute for peer review, and results should be checked before they are relied on.

The service is provided as it is, with no guarantee that it will always be available or free of faults. These terms may change; material changes will be announced in the app first.

A plain-language summary of intent, not a lawyer-reviewed document. Replace it with a real one before the lab takes payment or operates in a regulated market.
