These Terms of Service (“Terms”) form a binding agreement between Legend (“Company,” “we,” “us,” or “our”) and you, the user (“you” or “your”) regarding your access to and use of our website, Chrome extension, and related services (collectively, the “Service”).
By creating an account, signing in, installing the extension, or otherwise accessing the Service, you agree to these Terms and to our Privacy Policy, which is incorporated by reference. If you are using the Service on behalf of a school, district, or other organization, you represent that you have authority to bind that entity to these Terms.
If you do not agree to these Terms, do not access or use the Service.
Legend provides software tools designed to help teachers and schools grade student work, give feedback, build and share rubrics, and track student progress. The Service may use artificial intelligence to assist with these tasks.
The Service is intended for use by teachers, school staff, and educational institutions. It is not intended for direct use by students under 13, or for any consumer or non-educational purpose.
We may add, modify, or remove features at any time. We will try to give reasonable notice of material changes that adversely affect existing functionality.
To use the Service, you must be at least 18 years of age (or the age of majority in your jurisdiction), legally capable of entering into this agreement, and acting in a professional educational capacity (e.g., as a teacher, administrator, instructional coach, or authorized school staff member).
You agree to provide accurate and current information when creating your account and to keep that information up to date. You are responsible for safeguarding your login credentials and for all activity that occurs under your account.
You must notify us promptly at privacy@legend.org if you suspect unauthorized access to your account.
When you use the Service to process student work, you do so on behalf of your school or educational institution. You represent and warrant that:
Legend processes student data on behalf of teachers and schools, acting as a “School Official” with legitimate educational interest under FERPA. Our handling of student data is governed by our Privacy Policy and any data processing agreement signed between Legend and your school or district.
You agree not to:
We may investigate suspected violations and take appropriate action, including warning you, removing content, suspending or terminating accounts, and cooperating with law enforcement.
“Your Content” means assignments, rubrics, student submissions, comments, scores, settings, and any other materials you upload to or generate within the Service. As between you (and your school, where applicable) and Legend, you retain all rights in Your Content. Legend does not claim ownership of Your Content.
You grant Legend a worldwide, non-exclusive, royalty-free license to host, store, copy, transmit, display, and process Your Content solely as necessary to operate, secure, and improve the Service for you and your school, and to comply with legal obligations. We do not use identifiable student work to train generalized AI models; any use for product or model improvement is performed on de-identified and/or aggregated data, as described in our Privacy Policy.
If you choose to publish a rubric to Legend’s shared rubric library, you grant Legend and other users a worldwide, non-exclusive, royalty-free license to view, copy, adapt, and use that rubric within the Service. You are responsible for ensuring that any rubric you publish does not contain student data and does not infringe on anyone’s rights. You may unpublish a rubric at any time, but copies previously made by other users may continue to exist in their accounts.
If you send us suggestions, ideas, or feedback about the Service, you grant Legend a perpetual, irrevocable, royalty-free license to use that feedback for any purpose, without obligation to you.
The Service uses AI models to generate grades, feedback, summaries, and other output (“Output”). Output is intended as a starting point to support, not replace, your professional judgment as a teacher.
The Service integrates with third-party products such as Google (for authentication, Google Drive, and Google Classroom) and AI model providers such as OpenAI. Your use of those third-party products is governed by the relevant third party’s terms and privacy policies.
By connecting a third-party account to the Service, you authorize Legend to access and use information from that account as needed to provide the Service. You can disconnect a third-party account at any time from within the Service or from the third party’s settings.
Our use of information received from Google APIs adheres to the Google API Services User Data Policy, including the Limited Use requirements.
The Service, including its software, design, logos, documentation, and all other materials provided by Legend (excluding Your Content), is owned by Legend or its licensors and is protected by intellectual property laws.
Subject to your compliance with these Terms, Legend grants you a limited, non-exclusive, non-transferable, non-sublicensable, revocable license to access and use the Service for its intended educational purpose. All rights not expressly granted are reserved.
“Legend,” the Legend logo, and other Legend marks are trademarks of Legend. You may not use our trademarks without our prior written permission.
Portions of the Service may be offered free of charge, on a trial basis, or under a paid plan. If a paid plan applies to you, the specific fees, billing cycle, and renewal terms will be presented at the time of purchase or in a separate order form or agreement.
Unless otherwise stated in an applicable order form:
Free features and trials may be modified or discontinued at any time without notice.
Except as expressly stated in these Terms, the Service is provided “as is” and “as available,” without warranties of any kind, whether express, implied, or statutory. To the maximum extent permitted by law, Legend disclaims all warranties, including implied warranties of merchantability, fitness for a particular purpose, non-infringement, and any warranties arising out of course of dealing or usage of trade.
We do not warrant that the Service will be uninterrupted, error-free, secure, or that Output will be accurate, complete, or appropriate for any particular use. You are solely responsible for verifying Output and for any decisions you make based on it.
To the maximum extent permitted by law, Legend and its officers, directors, employees, affiliates, and suppliers will not be liable for any indirect, incidental, special, consequential, exemplary, or punitive damages, or for any loss of profits, revenue, data, goodwill, or business opportunity, arising out of or related to the Service or these Terms, even if we have been advised of the possibility of such damages.
Legend’s total aggregate liability arising out of or related to these Terms and the Service will not exceed the greater of (a) the amount you paid to Legend for the Service in the twelve (12) months immediately preceding the event giving rise to the claim, or (b) one hundred US dollars (US$100).
Some jurisdictions do not allow certain disclaimers or limitations of liability, so some of the above may not apply to you. In those jurisdictions, our liability is limited to the minimum extent permitted by law.
To the extent permitted by applicable law, you will indemnify, defend, and hold harmless Legend and its officers, directors, employees, and affiliates from and against any third-party claims, damages, liabilities, and expenses (including reasonable attorneys’ fees) arising out of or related to:
If you are a public school or other government entity, this section applies only to the extent permitted by applicable law.
These Terms apply from the moment you first access the Service and continue until terminated.
You may stop using the Service and delete your account at any time by following the in-product instructions or by contacting privacy@legend.org.
We may suspend or terminate your access, in whole or in part, if we reasonably believe that you have violated these Terms, that your use poses a security or legal risk, or that we are required to do so by law. Where feasible and appropriate, we will give you notice and an opportunity to address the issue before terminating.
On termination, your right to access the Service ends and we will delete or return Your Content in accordance with our Privacy Policy and any applicable school agreement. Sections that by their nature should survive termination (including intellectual property, disclaimers, limitation of liability, indemnification, and governing law) will survive.
We may update these Terms from time to time. If we make material changes, we will provide reasonable notice, for example by posting a notice within the Service, sending an email to your account address, or updating the “Last updated” date at the top of these Terms.
Your continued use of the Service after the effective date of updated Terms constitutes your acceptance of the updated Terms. If you do not agree, you should discontinue use of the Service and may request deletion of your account.

The courts located in Toronto, Ontario will have exclusive jurisdiction over any dispute arising out of or related to these Terms, except that either party may seek injunctive or equitable relief in any court of competent jurisdiction.
