DMCA and copyright policy

Last updated: November 9, 2026

GN Math respects the rights of creators. Every game on this site is open-source software that we host under the license its author chose, with credit on the game page and on the credits page. If you believe something here infringes your copyright, we want to hear about it and will act quickly.

How to send a takedown notice

Email contact@gnsmath.com with the subject "DMCA notice" and include:

  1. Your name, address, phone number and email.
  2. A description of the copyrighted work you believe is infringed.
  3. The exact page address(es) on GN Math where the material appears.
  4. A statement that you have a good-faith belief the use is not authorized by the copyright owner, its agent or the law.
  5. A statement, under penalty of perjury, that the information in your notice is accurate and that you are the copyright owner or authorized to act for the owner.
  6. Your physical or electronic signature.

What happens next

We review every complete notice promptly. If the claim is valid, or while we check a game's license with its author, we remove or disable the material and let you know. Because each game here is published under an open license, it helps to tell us whether your claim concerns the code, the art, the sound or the game's name.

Counter-notices

If you are the author of a game that was removed and you believe this was a mistake, email us a counter-notice with your contact details, the removed page address, a statement under penalty of perjury that the removal was a mistake or misidentification, and your signature. We may restore the material if the original claimant does not respond as described by law.

Repeat or bad-faith claims

Sending false claims can carry legal consequences. Please make sure the work is yours and is not already shared under an open license that allows this use. You can check each game's license on its page.

Other requests

Corrections to credits, license details or game descriptions do not need a formal notice. Just write to us through the contact page. See also our terms of use.
