Acceptance of terms
These Terms of Service (the “Terms”) are an agreement between you and CARL Hub Inc. (“CARL”, “we”, “us”), the operator of the CARL (Collaborative Academic Resource Library) platform. By creating an account or using CARL, you agree to these Terms and to our Privacy Policy.
- If you use CARL on behalf of a school, district, or other organization, you confirm that you have authority to bind that organization, and “you” includes it.
- If your school or district has a separate written agreement with CARL (for example, a District license), that agreement controls where it conflicts with these Terms.
- If you do not agree to these Terms, do not use CARL.
The CARL service
CARL is a platform for educators that provides lesson planning and authoring tools, AI-assisted content generation, worksheet and resource builders, a library of shared lessons and components, collections, profiles, and community features. Some features are available on a free plan; others require a paid Plus subscription or an organizational District license.
Compass is a companion product we operate with its own account and sign-in. If you choose to link your CARL and Compass accounts, the two products exchange information through a secure API connection to provide the integration, as described in the Privacy Policy. We may add, change, or remove features as the platform evolves. Where a change materially reduces the core functionality of a paid plan, we will provide reasonable advance notice.
Accounts and eligibility
You need an account to use most of CARL. You can register with an email address and password, sign in with Google, or sign in through your school district’s single sign-on. You agree to:
- Provide accurate, current, and complete information and keep it updated;
- Keep your credentials secure and accept responsibility for activity under your account;
- Notify us promptly of any unauthorized use of your account.
CARL is currently available to teachers, educators, and education organizations only; we do not offer student accounts. You must be an adult (the age of majority in your jurisdiction) to create an account. Accounts provisioned through a school or district may be managed, suspended, or removed by that organization.
Subscriptions and billing
Paid Plus subscriptions are billed monthly or yearly through our payment processor, Stripe. By subscribing you authorize recurring charges to your payment method.
- Automatic renewal. Subscriptions renew automatically at the end of each billing period until you cancel.
- Cancellation. You can cancel at any time from your plan settings. Cancellation takes effect at the end of the current billing period, and you keep paid features until then.
- Price changes. We may change prices with at least 30 days’ notice; changes apply from your next renewal.
- Refunds. Except where required by law, payments are non-refundable and we do not provide credits for partial billing periods.
- Free plan and usage limits. Free features, and usage limits on AI and other metered features, may change over time.
- District licenses. District plans are governed by the applicable ordering document or agreement with the school or district.
- Bundles. If you purchase a bundle through Compass that includes CARL, your CARL plan entitlement is managed through that purchase and the applicable Compass terms.
Your content
You retain ownership of the lessons, worksheets, components, comments, and other content you create or upload (“Your Content”). You grant CARL a non-exclusive, worldwide, royalty-free license to host, store, process, reproduce, display, and distribute Your Content solely as needed to operate, provide, secure, and improve the platform and as directed by your sharing settings. This license does not include using Your Content to train AI models.
- Visibility settings. Content is private by default. You control whether content is private, shared with specific people, or public.
- Public and shared content. When you make content public or share it, you grant other CARL users the right to view, save, and adapt (“remix”) it within the platform for educational purposes, with attribution to you. This license is granted by the user who shares the content, and CARL does not warrant that they have the rights to grant it.
- Your responsibilities. You represent and warrant that you own the content you upload or have all rights necessary to upload it and to grant the licenses in these Terms, including any rights held by your employer. Materials created in the course of your employment may belong to your school or district, and uploading them may require its permission. You are also responsible for ensuring uploaded content does not include personal information about students or other identifiable individuals without proper authority.
- Feedback. If you send us suggestions or feedback, we may use them without obligation to you.
AI features
CARL includes AI-assisted features such as lesson generation, curriculum-aligned content suggestions, editing assistance, and image generation. When you use these features, your prompts and the context you include are processed by CARL and by third-party AI providers acting as our service providers.
- No training on your data. We do not use Your Content or your personal information to train AI models, and we engage AI providers through business APIs under terms that do not permit them to use your inputs or outputs to train their models.
- Review outputs. AI-generated content may be inaccurate, incomplete, or inappropriate. You are responsible for reviewing outputs for accuracy, safety, cultural appropriateness, and suitability before classroom use. AI outputs are not professional advice.
- Ownership of outputs. As between you and CARL, and to the extent permitted by law, AI outputs you generate are part of Your Content.
- Fair use of limits. AI features are subject to plan-based usage limits. You may not circumvent limits or use AI features to build a competing dataset or service.
- Student information. Do not include personal information about students in AI prompts.
Privacy and data
Our Privacy Policy explains what information we collect and how we use it. In short: we do not sell personal information, and we do not use your content or personal information to train AI models.
Cultural content
CARL is built around culturally affirming and responsive learning, including content contributed by community stewards and knowledge holders. You agree to:
- Respect cultural knowledge, protocols, and perspectives shared on the platform;
- Use culturally specific content, including Indigenous knowledge, only as authorized and in line with any conditions the contributor attaches;
- Preserve attribution and acknowledge cultural contributions;
- Report content that misrepresents or misappropriates cultural knowledge.
Prohibited uses
You may not use CARL to:
- Violate any law or regulation, or infringe anyone’s rights;
- Harass, abuse, or harm others, or post hateful or discriminatory content;
- Upload malware or attempt to probe, disrupt, or bypass platform security;
- Scrape, bulk-download, or systematically copy platform content, or access the service by automated means other than interfaces we provide;
- Resell, sublicense, or commercially redistribute the platform or other users’ content without permission;
- Misrepresent your identity, affiliation, or credentials;
- Circumvent plan limits, metering, or access controls;
- Reverse engineer the platform except where the law permits it despite this term.
Intellectual property
The CARL platform — including its software, design, trademarks, and content we provide — is owned by CARL Hub Inc. or its licensors. We grant you a limited, non-exclusive, non-transferable license to use the platform for educational purposes in accordance with these Terms. No other rights are granted.
If you believe content on CARL infringes your copyright or other rights, contact us at [email protected] with enough detail to identify the content and your claim. We respond to valid notices, including by removing content, and may suspend repeat infringers.
Termination
You may stop using CARL and delete your account at any time from your settings. We may suspend or terminate your access if you materially breach these Terms, if required by law, or if your account is managed by an organization that requests it. Where practical, we will give you notice and an opportunity to export your content.
On termination, your license to use the platform ends and we handle your data as described in the Privacy Policy. Sections that by their nature should survive — including content licenses for content you shared publicly, disclaimers, limitations of liability, and governing law — survive termination.
Disclaimers and liability
CARL is provided on an “as is” and “as available” basis. To the maximum extent permitted by law, we disclaim all warranties, express or implied, including merchantability, fitness for a particular purpose, and non-infringement. Educational content on CARL — whether created by users, by CARL, or by AI — is not professional advice, and you remain responsible for your own teaching decisions.
To the maximum extent permitted by law, CARL Hub Inc. is not liable for indirect, incidental, special, consequential, or punitive damages, or for lost profits, data, or goodwill, and our total liability for all claims relating to the platform is limited to the greater of the amounts you paid us in the 12 months before the claim or CAD $100. You agree to indemnify us against third-party claims arising from your content or your breach of these Terms. Nothing in these Terms limits rights you have under mandatory consumer protection law.
Governing law
These Terms are governed by the laws of the Province of British Columbia and the federal laws of Canada applicable there, without regard to conflict of law rules. Disputes will be resolved in the courts of British Columbia, except where mandatory law gives you the right to bring proceedings where you live.
Changes to these terms
We may update these Terms from time to time. We will post the updated Terms on this page and revise the effective date, and for material changes we will give reasonable advance notice by email or in-product messaging. Your continued use of CARL after a change takes effect means you accept the updated Terms.
