Copyright, DMCA, and Takedown

1. Factual Data Versus Protected Content

Most of what we present, such as masses, distances, temperatures, and orbital figures, are facts and public-record measurements, which are generally not protected by copyright. However, real photographs and certain other materials are subject to copyright and are used under third-party licenses, for example images from ESO, ESA/Hubble, NASA, the Event Horizon Telescope, or Wikimedia Commons under public-domain or Creative Commons terms, with attribution. This policy applies to such protected materials.

2. Reporting Claimed Infringement (DMCA Notice)

If you are a copyright owner or authorized agent and believe content on the Service infringes your copyright, please send a written notice to our designated contact (below) that includes:

• identification of the copyrighted work you claim has been infringed;
• identification of the material you claim is infringing, with enough detail for us to locate it, including the URL on the Service;
• your name, mailing 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;
• a statement, made under penalty of perjury, that the information in your notice is accurate and that you are the copyright owner or authorized to act on its behalf; and
• your physical or electronic signature.

3. Where to Send Notices

Designated contact: email support@gravityfinder.com (please put “DMCA Notice” in the subject line). Mailing address: 137 Finder LLC, 30 Brown Bear Xing, Uxbridge, MA 01569, United States.

4. Our Response

Upon receiving a valid notice, we may remove or disable access to the material in question and take other action we consider appropriate. We may also notify the party who provided the material, where applicable.

5. Counter-Notification

If you believe your material was removed or disabled in error or misidentification, you may send a counter-notice to the contact above that includes:

• identification of the material that was removed and the location where it appeared before removal;
• a statement, under penalty of perjury, that you have a good-faith belief the material was removed as a result of mistake or misidentification;
• your name, mailing address, and telephone number, and a statement that you consent to the jurisdiction of the federal court for your district, or, if outside the United States, the federal court in Massachusetts, and will accept service of process from the complaining party; and
• your physical or electronic signature.

6. Repeat Infringers

In appropriate circumstances, we will limit access for, or bar, users who are repeat infringers. This applies primarily to user-submitted content; the current version of the Service does not host user submissions.

Photographs on the Service are used under their stated licenses with attribution. If you believe an image is mislicensed, misattributed, or should be removed, email support@gravityfinder.com with the page URL and details and we will review it promptly.

8. Misrepresentation

Under Section 512(f) of the DMCA, you may be liable for damages if you knowingly materially misrepresent that material is infringing or was removed by mistake.
