Terms of Use
We often hear laments from the educational community
about how the Internet has made plagiarism easier to commit. Sadly we find that we must agree:
Educators have plagiarised Purplemath lessons any number of times, frequently for profit, such
as appears to be the case with EduTech.
This "Terms of Use" page has been created in hopes of clarifying the issues involved.
Purplemath is the copyrighted property of Elizabeth
Stapel. While the lessons have been created as a labor of love and are designed to help struggling
students find success in algebra, Purplemath is not "in the public domain", and is subject
to the following terms and conditions.
- You are welcome to print out Purplemath content
for your own private use.
- You are welcome and encouraged to link to Purplemath,
and you may have links from your site to Purplemath pages that open in a new window. However,
you may not present Purplemath content framed within your site or any other site, nor in any
other manner imply an affiliation with, connection to, or endorsement by Purplemath or Elizabeth
Stapel.
- You may quote short portions of Purplemath content,
where said quotation falls under the "Fair Use" guidelines (such as quoting a representative
paragraph for the purpose of editorial review). You may not quote extensive portions of Purplemath
content; in particular, you may not present Purplemath content as your own work. Note that "Fair
Use" requires that your use be "limited" (not world-viewable), "brief"
(not the entire lesson), "immediate" (not a long-term or permanent part of your course),
and "transformative" (you can't use these lessons as your lessons, as this doesn't
"transform" the original work). Also, the use must include attribution (don't strip
out the copyright notices or authorship information) and must not affect marketability (do not
use bootleg copies of Purplemath as a learning resource to avoid paying a school license fee).
- You are welcome to download and distribute the
"Homework Guidelines" freely.
However, such distribution is to be free of charge to the recipient. In particular, you are not
to sell the "Homework Guidelines".
- You may link directly to lessons, though you
are encouraged to link to the index of
the lessons at "http://www.purplemath.com/modules/". If you link directly to lessons,
this linking is to be supplemental to your own teaching. For instance, you may not to present
Purplemath content as your own online lectures.
- Purplemath may not be incorporated into any other
product. In particular, you may not sell the content of Purplemath, or in any other manner lay
claim to the name or content of "Purplemath".
- You are authorized to retain copies of the content of this
web site only for your personal, non-commercial use, provided that you retain all copyright and
other proprietary notices contained in the original materials on any copies of the materials.
You may not modify the materials at this site in any way or reproduce or publicly display, perform,
or distribute or otherwise use them for any public or commercial purpose. Any use of these materials
on any other website or networked computer environment for any purpose is prohibited, unless
prior written permission has been obtained from Elizabeth Stapel, her agent, heirs, or assigns.
(One method of obtaining permission would be to purchase a site license,
whose terms would supercede these Terms.)
- Purplemath is not to be downloaded/uploaded,
"imported" via editors (such as FrontPage) or snaggers (such as SiteSnagger or WebCopier),
mirrored, burned, framed, or otherwise installed electronically on any server other than that
contracted with Elizabeth Stapel without the purchase of a site
license. For example, you may not use
Purplemath lessons as your lessons when teaching an online course, you may not present Purplemath
lessons as your own lecture notes, and you may not present Purplemath content as evidence of
your ability as an online instructor while pursuing a degree or employment.
- You may not "hotlink" to (have links
on your own page calling) graphics from Purplemath. You may not present Purplemath graphics as
your own.
- You may not present Purplemath graphics as part
of your own site without express prior written permission. If permission is granted, it will
be with the understanding that credit will be given, including a copyright notice, and a link
will be provided back to Purplemath.
- You may print out Purplemath lessons for limited
distribution, as long as the copyright information and URL are retained, as long as such distribution
is made at no cost to the recipient, and as long as said distribution is supplemental to your
own teaching. For instance, you may not use Purplemath lessons as the content of your tutoring
lessons for which you are being paid, nor may you use Purplemath lessons to replace the presentation
of lectures or the use of a textbook in your class.
- The content on Purplemath is copyrighted and any unauthorized
use of any Purplemath content may violate copyright, trademark, and other laws. If you breach
any of these Terms, your authorization to use Purplemath automatically terminates and you must
immediately destroy any downloaded, electronic, or printed materials.
- The following explicit exception to the
above is made in the case of the "Homework
Guidelines": You may post and/or
revise the "Homework Guidelines"
to suit your needs, as long as you include a reference to the original version residing at "http://www.purplemath.com/guidline.htm".
The reference shall include the preceding URL.
- The information presented on Purplemath is "as is",
and your use of the lessons is without guarantee or warranty. Specifically, neither Purplemath
nor Elizabeth Stapel accepts any liability regarding your course progress, grades, degree fulfillment,
or employability.
- Information regarding other sites and products is provided as

nor warrants them. If you decide to access these sites or products, you accept liability
for their use.
