Terms and Conditions

WHY. We are a small, independent publisher founded by a math teacher and his wife. We believe in the value we bring to teachers and schools, and we want to keep doing it. We keep our prices low so all teachers and schools can benefit from our products and services. We ask that you help us in our mission by complying with these Terms & Conditions.

PLEASE, NO SHARING. We know it’s nice to share, but please don’t share your membership content or your login or validation info. Your membership is a Single User License, which means it gives one person – you -- the right to access the membership content (Answer Keys, editable lesson files, pdfs, etc.) but is not meant to be shared.

Please do not copy or share the Answer Keys or other membership content.
Please do not post the Answer Keys or other membership content on a website for others to view. This includes school websites and teacher pages on school websites.
You can make copies of the Answer Keys to hand out to your class, but please collect them when the students are finished with them.
If you are a school, please purchase a license for each teacher/user.

PLEASE RESPECT OUR COPYRIGHT AND TRADE SECRETS. We own the copyright in all the materials we create, and we license certain copyrights in software we use to run our site, manage credentials and create our materials; some of this copyrighted software may be embedded in the materials you download. When you subscribe, we give you permission (a “Single User License”) to use our copyrights and trade secrets and those we license from others, according to our Terms & Conditions. So in addition to agreeing not to copy or share, we ask you:

Please don’t reverse-engineer the software; and please don’t change or delete any authorship, version, property or other metadata.
Please don’t try to hack our validation system, or ask anyone else to try to get around it.
Please don’t put the software, your login information or any of our materials on a network where people other than you can access it
Please don’t copy or modify the software or membership content in any way unless you have purchased editable files;
If you create a modified assignment using a purchased editable file, please credit us as follows on all assignment and answer key pages:

FEEDBACK REQUESTED. We value your feedback about our products and services. We think others will value it, too. That’s why we may do the following (and we ask that you agree):

Use your feedback to make improvements to our products and services and even launch new products and services, with the understanding that you will not be paid or own any part of the new or improved products and services (unless we otherwise agree in writing ahead of time).
Share your feedback, including testimonials, on our website or other advertising and promotional materials, with the understanding that you will not be paid or own any part of the advertising or promotional materials (unless we otherwise agree in writing ahead of time).

NO WARRANTY. We believe in the quality and value of our products and services, and we work hard to make sure they work well and are free of bugs. But that said, we are providing our products and services to you “as is,” which means we are not responsible if something bad happens to you or your computer system as a result of using our products and services. For our full Disclaimer of Warranties, please see our Legalese version of these Terms & Conditions Here.

DISPUTES. If we have a dispute that we cannot resolve on our own, we will use Binding Arbitration instead of filing a lawsuit in a regular court (except that you can use small claims court). Binding Arbitration means our case will be decided by one or more arbitrators who are chosen and paid by all parties to the dispute. Arbitration is a faster and less formal way of resolving disputes and therefore tends to cost less.

To begin an arbitration proceeding, please send a letter requesting arbitration and describing your claim to:

eMath Instruction, Inc.
10 Fruit Bud Lane
Red Hook, NY 12571

LIMITATION OF LIABILITY. If you do win a case against us, the most you can recover from us is the amount you have paid us.
