DMCA policy

Respect for copyright matters to us, and we respond to proper notices about material on percentage-increase-calculator.org. 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

To be effective, your written notice needs to contain all of the following:

1. A physical or electronic signature of the copyright owner or of someone authorised to act on the owner's behalf.
2. A description of the copyrighted work that you claim is infringed (for several works, a representative list is enough).
3. Identification of the material on percentage-increase-calculator.org that you claim is infringing, with enough detail for us to find it, ideally the full address of each page.
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

Send notices by email to [email protected], with “DMCA notice” in the subject line. We handle notices promptly, and if a notice is valid, the material is removed or access to it is disabled. If something is missing, we may ask you for it before we can act.

Counter-notification

If you believe material was removed in error, you can respond with a counter-notice to [email protected] that includes:

• your signature, physical or electronic;
• a description of the removed material and the location where it appeared;
• 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, 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.

Once we receive a valid counter-notice, we may restore the material within 10 to 14 business days unless the complainant informs us that they have gone to court.

Before you file

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 not sure whether a use infringes, perhaps because it could be fair use, it may be wise to get legal advice first.

Repeat infringement

Although the site does not host user uploads or accounts, in appropriate circumstances we will block access for repeat infringers.
