Terms of Use

Last updated: October 23, 2026

These Terms of Use (the “Terms”) set out the conditions for using CLI Campus (the “Service”), provided by Reed Craft (“we”). By using the Service, you agree to these Terms. This English version is provided for reference; if it differs from the Japanese version, the Japanese version prevails.

The Service

The Service is a free workbench for practicing command-line tools in your browser. No sign-up or login is required. Commands you type change only a virtual environment inside your browser. They are never run on your computer’s operating system or on real servers, and network commands such as curl, ssh, and docker pull do not reach the internet.

About the practice environment

• Each course is a simplified model of the real tool. Supported options, output, and error messages can differ from the real tools
• Before running a command on a real computer or server, check the tool’s official documentation and your own environment. We are not responsible for the results of commands run outside the Service

Saved progress

• Only which missions you have cleared is stored in your browser. The commands you type and the virtual files are kept in the page while it is open, and are lost when you reload or close it
• Progress can also be lost when you clear browser data or close a private window. Lost progress cannot be recovered, and we keep no copy

Prohibited conduct

The following are prohibited:

• Using the Service for illegal purposes
• Putting excessive load on our servers or network, unauthorized access, or anything else that interferes with the Service
• Copying, republishing, redistributing or selling the Service’s text or software beyond private use
• Infringing our rights or the rights of others

Do not type passwords, access keys, or personal information into the workbench.

Rights

Rights in the Service’s text, software and other content belong to us or their rightful owners. Product names that appear in the courses are trademarks of their respective owners.

Disclaimer

• For damage arising from use of the Service, except where caused by our intent or gross negligence, our liability is limited to direct damage that would ordinarily arise
• We are not responsible for progress lost because of the state of your browser or device
• We do not guarantee the continuity or quality of the Service

Maintenance and support

• We make no explicit promise about how often updates come, or what they contain
• We do not guarantee support for future browsers or devices
• We respond to bug reports and inquiries where we can, but cannot promise a reply or a fix

Changes and termination

We may change features of the Service or end it without prior notice.

Changes to these Terms

We may change these Terms when needed. Revised Terms take effect when posted on this page. Significant changes will be announced on this site in advance.

Governing law and jurisdiction

These Terms are governed by the laws of Japan, and disputes concerning the Service are subject to the jurisdiction of the courts of Japan.
