Copyright policy

Last updated October 2, 2026

Draft: this page still needs review by a lawyer and isn’t final legal advice.

Chaos lets people share lessons, courses, quizzes, flashcards and files. This page explains what you may share, how credit works, and what happens when someone reports a copyright problem. Questions: khomod14@gmail.com.

1. Share only what you have the right to share

• Upload or publish material only if you made it, you have permission, or the law or its licence allows you to share it.
• Uploading something to Chaos doesn’t transfer its copyright. You keep whatever rights you had, and so does the original owner.
• Publicly available doesn’t mean public domain. A page, slide deck or video you found online usually still belongs to someone.
• Private lessons and source files still need to respect copyright; private only limits who can see them.

2. Credit and attribution

• Keep the source and its author when you use someone else’s work. Lessons have a Sources panel and citations for this.
• When you copy a public lesson or quiz to your library, Chaos records where it came from and keeps the original author credited. Don’t remove or hide that credit.
• A copy of someone else’s quiz doesn’t include their answer key. If you republish a copy, the material in it must still be yours to share.

3. Reporting a copyright problem

If you believe material on Chaos infringes your copyright:

• Use Report on the lesson, course or comment and choose Copyright, or email khomod14@gmail.com.
• Include a link to the material, what work you believe it copies, and how we can contact you. Say whether you own the rights or act for the owner.
• Only report material you believe in good faith is infringing. False reports can lead to restrictions on the reporting account.

4. What happens next

• We review each report. While we do, we may temporarily hide or restrict the material.
• We tell the creator what was reported, without sharing the reporter’s private contact details unless the law requires it.
• If the report holds up, the material stays hidden or is removed. If it doesn’t, we restore it.

5. If your material was restricted

Creators can respond or appeal by replying to our message or emailing khomod14@gmail.com. Explain why you have the right to share it, for example your own work, a licence or permission. We’ll review the appeal and tell you the outcome.

6. Repeated problems

Accounts that repeatedly share material they don’t have the right to share may have content removed, publishing limited, or the account suspended.
