Copyright & DMCA

Sumiyomi respects the rights of authors, artists and publishers. If you believe content on Sumiyomi infringes your copyright, tell us and we will remove it or disable access to it promptly.

How to send a notice

Email [email protected] with the subject line Copyright notice. Under the U.S. Digital Millennium Copyright Act (DMCA), a notice must include:

  1. your physical or electronic signature, as the copyright owner or a person authorized to act on their behalf;
  2. a description of the copyrighted work you believe is being infringed;
  3. the exact address (URL) of each page on sumiyomi.com where the material appears;
  4. your name, postal address, telephone number and email address;
  5. a statement that you believe in good faith that the use is not authorized by the copyright owner, its agent or the law;
  6. a statement that the information in your notice is accurate and, under penalty of perjury, that you are the copyright owner or authorized to act on their behalf.

Notices from outside the United States are welcome too: please include the same information.

What happens next

We review every complete notice. When a notice is valid, we remove the material or disable access to it, and reply to let you know what we did. Incomplete notices can slow things down, so please include everything listed above.

If you think something was removed by mistake

If you believe material was removed because of a mistake or misidentification, email us with the subject line Counter-notice. Say which material was removed and where it appeared, explain why you believe it was a mistake, include your contact details, and state, under penalty of perjury, that you believe in good faith the material was removed by mistake.

Repeat infringement

We remove material that is repeatedly found to infringe, and we may block people who repeatedly post infringing content in comments.

False claims

Please make sure the material really infringes your rights before sending a notice. Under Section 512(f) of the DMCA, anyone who knowingly makes a material misrepresentation in a notice or counter-notice may be liable for damages.
