Copyright and DMCA Notices

Designated agent

This designation is also on file with the United States Copyright Office and can be verified in the DMCA Designated Agent Directory.

Sending a notice of claimed infringement

To be effective, your notice must include all of the following. This is what the statute requires, and a notice missing one of these elements may not be actionable:

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 claimed to have been infringed. Where several works are covered by a single notice, a representative list of them.
3. Identification of the material claimed to be infringing, with enough detail to let us locate it. For a share link, the full URL is enough.
4. Contact information for you: address, telephone number, and email address where available.
5. A statement that you have a good faith belief that the use is not authorized by the copyright owner, its agent, or the law.
6. A statement that the information in the notice is accurate, and, under penalty of perjury, that you are authorized to act on behalf of the owner of the right claimed to be infringed.

Please be aware that 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.

What we do with a notice

On receiving a notice that substantially complies with the requirements above, we will expeditiously remove or disable access to the material and make a reasonable attempt to notify the person who posted it. Share links can be disabled individually, and shared files are in any case deleted automatically 90 days after they are created.

Counter-notice

If you believe your material was removed by mistake or misidentification, you may send a counter-notice to the same agent. It must include:

1. Your physical or electronic signature.
2. Identification of the material 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 consenting to the jurisdiction of the Federal District Court for the judicial district in which your address is located (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 or their agent.

If we receive a valid counter-notice we will forward it to the person who sent the original notice. Unless that person notifies us that they have filed an action seeking a court order to restrain the activity, we may restore the material in 10 to 14 business days.

Repeat infringers

It is our policy, in appropriate circumstances, to disable access for and terminate the accounts of users who are repeat infringers. We keep a record of the notices we receive and the material they concern, and we take that record into account in deciding whether a person is a repeat infringer.

Reporting other problems

For material that is not a copyright matter (for example content that is unlawful or that discloses someone’s confidential information), use the report link on the shared page itself, or write to [email protected].

Use of the 3D viewer is also governed by its Terms of Use.
