Rex respects the intellectual property rights of others and expects its users to do the same. This policy explains how copyright owners can notify us of allegedly infringing material that a user has stored or published on Rex, how users can respond, and how we handle repeat infringers. We follow the notice-and-takedown process set out in the Digital Millennium Copyright Act, 17 U.S.C. § 512 ("DMCA").
1. What this policy covers
Rex lets users create study boards and publish interactive charts, quizzes, and other materials to the Rex community store, where other users can discover and use them. Those materials are created and uploaded by users, not by Rex. This policy applies to that user-generated content, and to any other material stored on our systems at the direction of a user.
If you believe material on Rex infringes a copyright you own or are authorized to act for, you may send us a takedown notice as described below. We will respond expeditiously to notices that substantially comply with the DMCA.
2. Where to send a notice
Send copyright notices to:
Email is the fastest and preferred route, and is all we require — you do not need to mail us a physical copy. We monitor this address and treat copyright notices as a priority.
3. Submitting a takedown notice
To be effective under 17 U.S.C. § 512(c)(3), your written notice must include substantially all of the following:
- A physical or electronic signature of the copyright owner, or a person authorized to act on the owner's behalf.
- Identification of the copyrighted work claimed to have been infringed. If multiple works at a single site are covered by one notice, a representative list of those works.
- Identification of the material claimed to be infringing, with enough detail for us to locate it — for a published chart, include its exact title and, where possible, the creator's username and the in-app link or chart identifier.
- Your contact information: name, mailing address, telephone number, and email address.
- A statement that you have a good-faith belief that the disputed use is not authorized by the copyright owner, its agent, or the law.
- A statement that the information in the notice is accurate, and, under penalty of perjury, that you are the copyright owner or are authorized to act on the owner's behalf.
Notices that are incomplete may not be actionable. Under 17 U.S.C. § 512(f), a person who knowingly and materially misrepresents that material is infringing may be liable for damages, including costs and attorneys' fees. If you are unsure whether the material infringes your copyright, or whether it is protected by fair use, you should consult a lawyer before sending a notice.
4. What we do when we receive a notice
- We review the notice and, where it substantially complies with the DMCA, expeditiously remove or disable access to the identified material. Published charts are hidden from the community store.
- We take reasonable steps to notify the user who posted the material, and provide them a copy of the notice.
- We inform the user that the material has been removed and that they may submit a counter-notice.
- If a notice is clearly deficient, we may ask you for the missing information before acting.
We aim to acknowledge notices within 2 business days and to complete our review promptly thereafter.
5. Counter-notification
If your material was removed and you believe the removal was the result of a mistake or misidentification, you may send a counter-notice to the agent listed above. Under 17 U.S.C. § 512(g)(3), it must include:
- Your physical or electronic signature.
- Identification of the material that was removed and the location at which it appeared before removal.
- A statement under penalty of perjury that you have a good-faith belief the material was removed or disabled as a result of mistake or misidentification.
- Your name, address, and telephone number.
- A statement that you consent to the jurisdiction of the U.S. District Court for the judicial district in which your address is located (or, if your address is outside the United States, any judicial district in which Rex may be found), and that you will accept service of process from the person who submitted the original notice or their agent.
If we receive a valid counter-notice, we will forward it to the person who submitted the original notice. Unless that person notifies us within 10 business days that they have filed an action seeking a court order to restrain the allegedly infringing activity, we may restore the material in not less than 10 and not more than 14 business days after receiving the counter-notice.
Under 17 U.S.C. § 512(f), knowingly and materially misrepresenting that material was removed by mistake or misidentification may also result in liability for damages.
6. Repeat-infringer policy
In accordance with 17 U.S.C. § 512(i), Rex has adopted and reasonably implements a policy of terminating, in appropriate circumstances, the accounts of users who are repeat infringers.
- Each takedown notice we act on is recorded against the account that posted the material.
- An account that accumulates repeated substantiated infringement claims will lose publishing privileges and may be terminated.
- We may terminate an account immediately, without prior warning, for a single instance of severe or willful infringement.
- Strikes may be withdrawn where the associated notice is retracted, successfully countered, or determined to be invalid.
7. Trademark and other rights
To report content that misuses your trademark, impersonates you or your organization, or violates rights other than copyright, email rexstudyapp@gmail.com with a description of the right you hold, the content at issue, and your contact information. These reports are handled under our Community Guidelines rather than the DMCA process.
8. Rex's own content
The Rex app, its name, logo, mascot, design, code, and Rex-authored charts and materials are owned by or licensed to Rex and are protected by copyright and trademark law. Nothing in this policy grants you any right to use them. See section 9 of our Terms of Service.
9. Changes to this policy
We may update this policy from time to time. The "last updated" date above reflects the most recent revision. Material changes will be noted in-app or by email.
