Terms of Service Privacy Policy Cookie Policy Refund Policy Support
This Copyright & DMCA Policy explains who owns the material on ActiveBook (the website at activebook.ai and the ActiveBook apps, together the “Service”, operated by Linus Publications, Inc.), how third-party material is credited, and how to report or contest a copyright complaint. It is part of our Terms of Service.
1. Ownership of the Service and its content
- The Service itself — its software, design, interface, logos, and the “ActiveBook” name and marks — is owned by Linus Publications, Inc. or its licensors.
- Books and learning materials on the Service (“Content”) are owned by their respective authors, publishers, or other rights holders, who license them to us for distribution through the Service.
- Reviews, notes, and annotations remain the property of the users who create them, licensed to us as described in the Terms of Service.
2. Author warranties
Authors and instructors who publish on ActiveBook warrant that they own, or are licensed to use and distribute, everything they upload — including text, images, figures, data sets, exercises, and interactive or embedded materials — and that their Content does not infringe any third party’s rights. Authors are responsible for securing permissions for any third-party material their Content incorporates.
3. Third-party materials, sources, and attribution
- Content may lawfully incorporate third-party material — for example quotations, excerpts, figures, photographs, open-licensed works (such as Creative Commons material), and interactive HTML embeds or simulations supplied by third parties.
- Such material remains the property of its respective owners. Where a license requires it, source credits and attribution notices appear alongside the material or in the book’s credits/sources section, and those notices must not be removed.
- Interactive embeds run inside the reader in a restricted environment and are provided as part of the book they belong to. Their inclusion does not imply the owner’s endorsement of ActiveBook.
- If you believe an attribution is missing or incorrect, contact legal@activebook.ai and we will review it with the author.
4. AI-assisted content
Some Content, or portions of it, may be created with the assistance of artificial-intelligence tools. Authors remain responsible for AI-assisted material they publish, including its accuracy and its compliance with copyright law. AI-assisted material is subject to this Policy and to the takedown procedure below in the same way as any other material on the Service.
5. What you may and may not do with content
- Purchasing Content gives you a personal license to read and use it through the Service, as described in the Terms of Service. Personal, non-commercial use — including study, coursework, and brief quotation with attribution as permitted by law (for example fair use) — is welcome.
- You may not copy, scrape, download, redistribute, republish, sell, or publicly display Content from the Service, and you may not remove copyright or attribution notices or circumvent content-protection measures.
6. Reporting copyright infringement (DMCA notice)
We respect the intellectual-property rights of others and respond to notices submitted under the U.S. Digital Millennium Copyright Act (DMCA) and equivalent laws. If you believe material on the Service infringes your copyright, send a written notice to our designated agent:
Copyright Agent, Linus Publications, Inc.
Email: dmca@activebook.ai
Your notice must include:
- your physical or electronic signature;
- identification of the copyrighted work you claim is infringed (or a representative list);
- identification of the allegedly infringing material and information reasonably sufficient for us to locate it on the Service (for example, the book title and chapter, or a URL);
- your contact information (name, address, telephone number, and email address);
- a statement that you have a good-faith belief that the use is not authorized by the copyright owner, its agent, or the law; and
- a statement, under penalty of perjury, that the information in the notice is accurate and that you are the copyright owner or authorized to act on the owner’s behalf.
On receiving a valid notice we will remove or disable access to the identified material promptly, notify the user who posted it, and take reasonable steps to forward them a copy of the notice. Knowingly making a false claim of infringement can expose you to liability under 17 U.S.C. § 512(f).
7. Counter-notification
If material you posted was removed and you believe the removal was a mistake or misidentification, you may send a counter-notification to dmca@activebook.ai including: your physical or electronic signature; identification of the removed material and where it appeared; a statement under penalty of perjury that you have a good-faith belief the material was removed by mistake or misidentification; your name, address, and telephone number; and a statement that you consent to the jurisdiction of the federal court for your address (or, if outside the United States, any judicial district in which we may be found) and that you will accept service of process from the person who filed the original notice. Unless the original claimant files a court action, we may restore the material in 10–14 business days.
8. Repeat infringers
We will, in appropriate circumstances, suspend or terminate the accounts of users or authors who are determined to be repeat infringers.
9. Trademarks
“ActiveBook”, the ActiveBook logo, and related names and marks are trademarks of Linus Publications, Inc. You may not use them without our prior written permission, except to accurately refer to the Service. Other names and marks appearing on the Service belong to their respective owners.
