3. Personal, Non-Commercial Use Only
You agree to use the Desmos Services only (a) as an end user, for your personal, non-commercial use or (b) as a teacher, for academic use by you and your students in individual classes. Desmos does, pursuant to a separate written agreement, permit certain third parties (y) to integrate with the Desmos Services for commercial use, and (z) to use the graphing calculator to generate graphs for commercial uses (including textbooks). Please contact info@Desmos.com for more information about entering into a relationship with Desmos that would permit commercial use of the Desmos Services.
4. User Submissions and Generated Materials
Desmos does not claim ownership of any materials (other than the underlying software and other materials of Desmos and its licensors used to generate such materials), lessons, formulae, information, data, text or other materials you submit and create for display or distribution to others through the Desmos Services, or the graphs generated therefrom (collectively, “User Submissions and Generated Materials”). As between Desmos and you, you own all rights to your User Submissions and Generated Materials. You grant to Desmos an irrevocable, perpetual, non-exclusive, fully-paid, worldwide, license, with the right to sublicense through multiple tiers, to use, distribute, reproduce, modify, adapt, publish, translate, publicly perform, and publicly display your User Submissions and Generated Materials (in whole or in part) in any format or medium now known or later developed. You acknowledge and agree that all right and title in the software code and other material used to create or display your User Submissions and Generated Materials is the property of Desmos, and you hereby assign all right and title in such material to Desmos. Desmos hereby grants you a license to such material (a) as an end user, for your personal, non-commercial use or (b) as a teacher, for academic use by you and your students in individual classes. Desmos reserves the right to display advertisements in connection with User Submissions and Generated Materials and to use User Submissions and Generated Materials for advertising and promotional purposes. Desmos does not pre-screen User Submissions and Generated Materials and you agree that you are solely responsible for all of your User Submissions and Generated Materials. Desmos is not required to host, display, or distribute any User Submissions and Generated Materials, and may remove at any time or refuse any User Submissions and Generated Materials. Desmos is not responsible for any loss, theft or damage of any kind to any User Submissions and Generated Materials. You represent and warrant that your User Submissions and Generated Materials, and Desmos' authorized use thereof, do not and will not infringe the rights of any third party (including, without limitation, intellectual property rights, rights of privacy or publicity, or any other legal or moral rights).
5. Special Terms for Educators
a. Fees. If Desmos makes any Desmos Service (e.g., the Desmos Graphing Calculator or the Desmos Activity Builder) available to Educators for academic use in individual classes with students without charging a fee, then Desmos will not thereafter charge Educators a fee to use such existing Desmos Service for such purpose. The foregoing will not, however, prohibit Desmos from charging a fee for any new Desmos Services that are complementary to, or may be used together with, such existing Desmos Service.
b. Activity Sharing. At the time you, as an Educator, submit to Desmos an activity you’ve developed using the Desmos Activity Builder (an “Activity”), you may elect to make your Activity public. If you do so, then you expressly authorize Desmos to (i) make your Activity available to other Educators for use in individual classes with other students, (ii) allow other Educators to copy and modify your Activity and use the modified version in individual classes with other students and (iii) modify your Activity and make the modified version available to other Educators for use in individual classes with other students. In the case of any such use of your Activity (whether unmodified or modified), you will receive an attribution credit. If you elect to make your Activity public, in no event will Desmos authorize any third party to sell your Activity to others, or to otherwise use your Activity for commercial purposes, without your permission.
6. Copyright Infringement
Desmos respects the intellectual property rights of others. Accordingly, Desmos has a policy of removing User Submissions and Generated Materials that violate copyright law, and, in appropriate circumstances, suspending access to the Desmos Services (or any portion thereof) to any user who uses the Desmos Services in violation of copyright law, and/or terminating the account of any user who uses the Desmos Services in violation of copyright law. Pursuant to Title 17 of the United States Code, Section 512, Desmos has implemented procedures for receiving written notification of claimed copyright infringement and for processing such claims in accordance with such law.

8. Termination and Suspension
Without limiting other remedies, Desmos may terminate or suspend your Desmos Services membership or suspend your access to all or part of the Desmos Services without notice if Desmos believes that you have violated these Terms or have engaged in conduct that violates applicable law or is otherwise harmful to the interests of Desmos, any other Desmos Services user, or any third party. You may discontinue your use of the Desmos Services at any time.
Subject to Section 5.a of these Terms, Desmos reserves the right to charge fees for access to new Desmos Services or to portions or uses of the existing Desmos Services. In no event will you be charged for access to any Desmos Services, unless Desmos obtains your prior agreement to pay such fees. If you do not consent to the payment of such fees, however, Desmos may prohibit your access to paid content or services. Details regarding the services you will receive in exchange for the payment of fees, as well as any payment terms and conditions that apply, will be disclosed to you prior to your agreement to pay such fees. All such terms will be deemed to be a part of (and are hereby incorporated by reference into) these Terms.
10. Password and Security
You are responsible for maintaining the confidentiality of your Desmos Services password, and you are solely responsible for all activities that occur under your password. You agree to immediately notify Desmos of any unauthorized use of your password or any other breach of security related to the Desmos Services. Desmos may require you to alter your password if Desmos believes that your password is no longer secure.
11. Third Party Services
Desmos may integrate with or provide links to certain third party Internet sites and services (for example, Zendesk, Google, and Twitter) (collectively, such third parties, “Linked Partners”). The Linked Partner services made available through the Desmos Services or the integration of the such sites and services with the Desmos Services are for your convenience only and do not signify the endorsement by Desmos of such Partner sites or services.
12. Disclaimer and Limitations of Liability
a. You agree that use of the Desmos services is at your sole risk. The Desmos services are provided on an “as is” and “as available” basis. Desmos expressly disclaims all warranties of any kind, whether express or implied, with respect to the Desmos services and all services provided by any of our partner (whether api partners, linked partners, or otherwise), including, but not limited to, the implied warranties of merchantability, fitness for a particular use or purpose, and non-infringement. You acknowledge that access to data and materials (including, but not limited to, your or others’ user submissions and generated materials) available through the Desmos services is not guaranteed and that Desmos will not be responsible to you for any loss of data or materials caused by the Desmos services or their unavailability. You understand and agree that any data, materials, services and/or information downloaded or otherwise obtained through the use of the Desmos services is done at your own discretion and risk and that you will be solely responsible for any damage arising therefrom.
b. Under no circumstances will Desmos or its officers, employees, directors, shareholders, agents, or licensors be liable under any theory of liability (whether in contract, tort, statutory, or otherwise) for any damages whatsoever, including direct, indirect, incidental, special, consequential or exemplary damages, including but not limited to, damages for loss of money, revenues, profits, goodwill, use, data or other intangible losses (even if such parties were advised of, knew of or should have known of the possibility of such damages), resulting from your (or anyone using your account's) use of the Desmos services.
c. If, notwithstanding these Terms, Desmos is found to be liable to you or any third party in connection with your use of the Desmos services, the total liability of Desmos and its officers, employees, directors, shareholders, agents, or licensors to you or to any third party is limited to one hundred U.S. Dollars ($100).
d. Exclusions And Limitations. Some jurisdictions do not allow the exclusion of certain warranties or the limitation or exclusion of liability for certain damages. Accordingly, some of the above limitations and disclaimers may not apply to you. To the extent that Desmos may not, as a matter of applicable law, disclaim any implied warranty or limit its liabilities, the scope and duration of such warranty and the extent of Desmos’ liability will be the minimum permitted under such applicable law.
You agree to indemnify, defend, and hold harmless Desmos and its officers, directors, employees, consultants and agents from and against any and all claims, liabilities, damages, losses, costs, expenses, fees (including reasonable attorneys' fees) that such parties may incur as a result of or arising from your (or anyone using your account's) violation of these Terms. Desmos reserves the right, at its own expense, to assume the exclusive defense and control of any matter otherwise subject to indemnification by you, and in such case, you agree to cooperate with Desmos’ defense of such claim.

You are not authorized to use any such Marks. Ownership of all such Marks and the goodwill associated therewith remains with Desmos or those other entities.
