TermsTerms of use

Last updated September 26, 2026. These terms cover this website. They do not cover the software. Every package Fusion publishes is MIT licensed, and the LICENSE file in the repository is the complete agreement for the software. The site is provided as is The site contains reference material and articles. We do not promise that it is complete, current, or correct. Nothing on the site is advice, so check it before you act on it. If a page and the code disagree, the code is correct. We may change or remove any part of the site at any time. Nothing on the site is an offer, and reading it does not create a relationship between you and us. We agree terms for paid work separately, in writing. The sandbox runs your code in your browser /helix/sandbox and /helix/theme run the code you type into them. Your code runs inside an iframe with sandbox="allow-scripts allow-forms". The iframe does not have allow-same-origin, so the document runs with an opaque origin. It cannot read our cookies or storage, call our origin, or reach any of our systems. It is your code, running in your browser. This has two consequences: We do not receive what you type. The source you edit is never sent to a server, so we cannot keep it, and we do not. We are not responsible for what your code does in your own browser. Do not paste a secret into the sandbox, for the same reason you would not paste one into a browser console: you have no way to confirm that we do not read it. What you may not do Do not use the site to: attack the site or anyone else break the law present yourself as us Do not scrape the site in a way that slows it down for other people. The documentation is also published as plain Markdown beside every page and as llms.txt, which is the cheaper way to read it for both of us. Liability We provide the site without warranties of any kind. To the extent the law allows, Fusion Development Group is not liable for any loss that arises from your use of the site. We are a small company, and this is the limit of liability we can stand behind. Governing law and changes to these terms The law of the State of Delaware, United States, governs these terms. When we change them, we update the date at the top, and the previous wording stays in the repository's history, where anyone can read it.
