Copyright Policy

Effective Date: April 1, 2026 · Last Updated: April 1, 2026

Theostack is a theological research platform operated by Lordhill Digital LLC. Our library is curated for pastors, and we take the intellectual property of authors and publishers seriously. This page explains how we approach copyrighted material, how rights holders can raise concerns, and how we handle formal takedown requests under the Digital Millennium Copyright Act (DMCA).

Our Approach to the Library

Theostack's theological library is hand-curated, not scraped from the internet. Every work in the library is reviewed before inclusion, and each document is evaluated for both theological quality and copyright status.

The library is built on three categories of content:

Public domain works. The majority of the library consists of works whose copyright has expired, including writings by the church fathers, the Reformers, the Puritans, and other historical theologians. These works are freely available and form the foundation of the library.

Confessional and creedal documents. Historic confessions of faith, catechisms, and creedal statements are included as foundational reference material.

Companion research documents. For works that remain under copyright, Theostack does not serve the original text to users. Instead, we generate original companion research documents that summarize, contextualize, and interact with the ideas in a given work. These companion documents are Theostack's own derivative content. They attribute the original author and title so that users know where the ideas originate, but the text itself is original to Theostack. This approach is designed to respect the rights of living authors and active publishers while still allowing pastors to discover and engage with relevant scholarship.

We do not host, distribute, or make available for download any copyrighted books, articles, or publications in their original form. Theostack is a research tool, not a file-sharing service. Our goal is to help pastors find the right sources for their work, and in doing so, to drive readers toward the original works and their publishers.

For Authors and Publishers

We understand that seeing your work referenced in an AI-powered platform can raise questions. We welcome those questions, and we would rather hear from you directly than learn about a concern secondhand.

If you are an author or publisher and you have questions about how your work appears in Theostack, here is what we want you to know:

We are reachable and responsive. You can contact us at hello@theostack.com with any questions or concerns about how your work is represented. We aim to respond within five business days.

We can show you what we have. If you want to know whether a specific work is in our library and how it is being used, we are happy to share that information with you directly.

We can adjust how your work is handled. If you are not comfortable with how a particular work is represented in the library, we have several options available. We can convert the entry to a companion research document if it is not already in that format. We can adjust the attribution or metadata. We can remove the work from the library entirely. We will work with you to find a resolution that respects your rights and serves our users well.

We value the work of theological authors. Theostack exists because we believe that what pastors read and cite matters. We have no interest in undermining the authors whose work we are trying to surface. If a pastor discovers a book through Theostack that they would not have found otherwise, that is a win for the author, the publisher, and the pastor.

Formal DMCA Takedown Process

If you are a copyright owner or an agent authorized to act on behalf of one, and you believe that content hosted on Theostack infringes your copyright, you may submit a formal takedown notice under the Digital Millennium Copyright Act (17 U.S.C. Section 512).

How to Submit a DMCA Notice

Your notice must include all of the following:

  1. A physical or electronic signature of the copyright owner or a person authorized to act on their behalf.
  2. Identification of the copyrighted work you claim has been infringed. If your notice covers multiple works, you may provide a representative list.
  3. Identification of the material you claim is infringing, with enough detail for us to locate it within the Service (for example, the title, author, and a description of the content you believe infringes your rights).
  4. Your contact information, including your name, mailing address, telephone number, and email address.
  5. A statement that you have a good faith belief that the use of the material in the manner complained of is not authorized by the copyright owner, its agent, or the law.
  6. A statement, made under penalty of perjury, that the information in the notice is accurate and that you are the copyright owner or are authorized to act on the copyright owner's behalf.

Where to Send Your Notice

DMCA notices should be sent to our designated agent:

Lordhill Digital LLC
Attn: DMCA Agent
PO Box 450, Glen Rose, TX 76043
Email: hello@theostack.com

What Happens After We Receive a Valid Notice

Upon receiving a complete and valid DMCA notice, we will:

  1. Acknowledge receipt within two business days.
  2. Review the claim and investigate the identified content.
  3. If the claim is substantiated, promptly remove or disable access to the infringing material.
  4. Notify the user who posted the material (if applicable) and provide them with a copy of the notice.

We aim to resolve valid claims within ten business days of receipt.

Counter-Notification

If you are a user of Theostack and you believe that content you uploaded or contributed was removed in error, you may submit a counter-notification. Your counter-notification must include:

  1. Your physical or electronic signature.
  2. Identification of the material that was removed and the location at which it appeared before removal.
  3. A statement under penalty of perjury that you have a good faith belief the material was removed as a result of mistake or misidentification.
  4. Your name, address, and telephone number, and a statement that you consent to the jurisdiction of the federal court in your district (or, if outside the United States, any judicial district in which Lordhill Digital LLC may be found) and that you will accept service of process from the person who submitted the original notice.

Counter-notifications should be sent to the same address listed above for DMCA notices.

Upon receiving a valid counter-notification, we will forward it to the original complaining party and restore the removed material within 10 to 14 business days unless the complaining party notifies us that they have filed a court action.

Repeat Infringers

Theostack maintains a policy of terminating the accounts of users who are repeat infringers, in appropriate circumstances and at our sole discretion.

Questions

If you are unsure whether your concern requires a formal DMCA notice or if you simply want to have a conversation about how your work appears on Theostack, we encourage you to reach out informally first. Most concerns can be resolved with a simple email.
