DMCA

Concrete Calculator respects the intellectual property of others and expects visitors to do the same. If you believe something on the site infringes your copyright, this page explains how to notify us under the Digital Millennium Copyright Act, 17 U.S.C. §512.

Filing a copyright notice

Please make sure your notice includes each of these elements, as required by 17 U.S.C. §512(c)(3):

1. A physical or electronic signature of the copyright owner or of someone authorised to act on the owner's behalf.
2. Identification of the copyrighted work you believe has been infringed, or a representative list if one notice covers several works.
3. Information that lets us locate the material you object to, such as the exact URL of each page on calculator-concrete.org.
4. How to reach you: your name, address, telephone number and email.
5. A statement that you believe in good faith that the use is not authorised by the owner, the owner's agent or the law.
6. A statement that the information in the notice is accurate and, under penalty of perjury, that you are the owner or authorised to act on the owner's behalf.

Contact for notices

Please email your notice to [email protected] and put “DMCA notice” in the subject. We review notices promptly. When a notice is complete and valid, we remove or disable access to the material and let you know. If something is missing, we may ask you for it before we can act.

Responding to a removal

If material you provided was removed and you believe this was a mistake or a misidentification, you may send a counter-notice to the same address. It must include:

• a physical or electronic signature;
• a description of the removed material and the location where it appeared;
• a statement under penalty of perjury that you believe in good faith that the removal was due to a mistake or misidentification;
• your name, address and telephone number, a statement that you consent to the jurisdiction of the federal district court for your address (or, if you are outside the United States, any judicial district in which the service provider may be found), and that you will accept service of process from the person who sent the original notice.

Following a valid counter-notice, the material can be put back after 10 to 14 business days, unless we hear that the complainant has started legal proceedings.

Misrepresentation

Be aware that 17 U.S.C. §512(f) makes a person who knowingly and materially misrepresents infringement, or a mistaken removal, liable for damages, including costs and attorneys' fees. If you are unsure whether a use is infringing, for example because it may be fair use, consider seeking legal advice before you send a notice.

Repeat infringement

calculator-concrete.org has no user accounts or uploads, but where it applies, we will, in appropriate circumstances, cut off access for anyone who repeatedly infringes copyright.
