Terms of Service

Effective July 1, 2019


Thank You For Using XNAT Academy!

XNAT Academy has been created and is run by the XNAT Team at the Computational Imaging Laboratories (CIL) in the Washington University School of Medicine. These Terms of Use ("Terms") govern your use of the XNAT Academy website and other products and services ("Services"). Please read these Terms carefully, and contact us if you have any questions. By using our Services, you agree to be bound by these Terms, including the policies referenced in these Terms. 


Using XNAT Academy

Who May Use our Services 

You may use our Services only if you can form a binding contract with XNAT Academy, and only in compliance with these Terms and all applicable laws. When you create your XNAT Academy account, and subsequently when you use certain features, you must provide us with accurate and complete information, and you agree to update your information to keep it accurate and complete. Any use or access by anyone under the age of 13 is prohibited, and certain courses may have additional requirements and/or restrictions.   

Our License to You 

Subject to these Terms and our policies (including the Acceptable Use Policy, Honor Code, and course-specific eligibility requirements and other terms), we grant you a limited, personal, non-exclusive, non-transferable, and revocable license to use our Services. You may download content from our Services only for your personal, non-commercial use, unless you obtain XNAT Academy's written permission to otherwise use the content. You also agree that you will create, access, and/or use only one user account, and you will not share with any third party access to or access information for your account. Using our Services does not give you ownership of any intellectual property rights in our Services or the content you access.  


Our Courses

Course Modifications 

XNAT Academy reserves the right to cancel, interrupt, or reschedule any course or to modify any course content or the point value or weight of any assignment, quiz, or other assessment.   

No Academic Credit

Unless otherwise explicitly indicated by a credit-granting institution, participation in or completion of a course does not confer any academic credit. Even if credit is awarded by one institution, there is no presumption that other institutions will accept that credit. You agree not to accept credit for completing a course unless you have earned a Course Certificate for that course. XNAT Academy, the course instructors, and the associated participating institutions have no obligation to have a course recognized by any educational institution or accreditation organization. 

Disclaimer of Student-University Relationship 

Nothing in these Terms or otherwise with respect to your participation in any course: (a) establishes any relationship between you and any educational institution with which XNAT Academy may be affiliated; (b) enrolls or registers you in any educational institution, or in any course offered by any educational institution; or (c) entitles you to use the resources of any educational institution beyond participation in the course.    



We care about the security of our users. While we work to protect the security of your account and related information, XNAT Academy cannot guarantee that unauthorized third parties will not be able to defeat our security measures. Please notify us immediately of any compromise or unauthorized use of your account by emailing

XNAT Academy cannot guarantee that such third party content, in the Services or elsewhere, will be free of material you may find objectionable or otherwise inappropriate or of malware or other contaminants that may harm your computer, mobile device, or any files therein. XNAT Academy disclaims any responsibility or liability related to your access or use of such third party content.  


Copyright and Trademark Policy

XNAT Academy respects the intellectual property rights of our users and third parties and expects our users to do the same when using the Services.

Paid Services

XNAT Academy offers paid Services (e.g., Course Certificates for certain courses) for a fee. Unless otherwise stated, all fees are quoted in U.S. Dollars. You are responsible for paying all fees and applicable taxes in a timely manner with a payment mechanism associated with the applicable paid Services. If your payment method fails or your account is past due, we may collect fees using other collection mechanisms. Fees may vary based on your location and other factors, and XNAT Academy reserves the right to change any fees at any time at its sole discretion. Any change, update, or modification will be effective immediately upon posting through the relevant Services. Refunds may be available for paid Services as described in our Refund Policy. 

All payments are processed by Washington University School of Medicine, using the secure online storefront powered by CashNet. XNAT Academy does not retain any credit card information, and does not accept payments by any other means.   


Modifying and Terminating our Services

We are constantly changing and improving our course offerings, and the course learning platform is often updated as well. We may add or remove functions, features, or requirements, and we may suspend or stop a Service altogether. Accordingly, XNAT Academy may terminate your use of any Service for any reason. If your use of a paid Service is terminated, a refund may be available under our Refund Policy. None of XNAT Academy, its contributors, sponsors, and other business partners, and their employees, contractors, and other agents shall have any liability to you for any such action. You can stop using our Services at any time, although we'll be sorry to see you go.

XNAT Academy Refund Policy   

Effective: July 1, 2019 

For details on our refund deadlines and policies, please refer to the information below. Please note that we treat violations of our Terms of Use and Honor Code very seriously, and we have no obligation to offer refunds to learners who are found to be in violation of these terms, even if their requests are made within the designated refund period. Similarly, we have no obligation to offer late refunds to learners who do not pass a course, or who are otherwise unsatisfied with their final grade.  

For Course Purchases

If you cancel your paid enrollment for a course, XNAT Academy will offer you a complete refund until 14 days after payment, or until you have earned your Course Certificate, whichever is earlier. If you pre-enroll and pay for a course, XNAT Academy will offer you a complete refund until 14 days after the course launches or until you have earned your Course Certificate, whichever is earlier. For avoidance doubt, once you have earned a Course Certificate with your payment, you are not eligible for a refund even if it is within 14 days. If you do not earn your Course Certificate within 180 days, your registration will expire and you will need to pay to re-enroll for the course.  

Notwithstanding the foregoing, shorter refund periods may apply to specific course. In these cases, the shorter period will be stated as part of the sign-up process for the course.
