Terms of Service

These Terms of Service govern your use of limerse.com and the interactive textbooks, lessons, accounts, and related services provided by Limerse. By creating an account, signing in, or otherwise using Limerse, you agree to these Terms. Our Privacy Policy explains how we handle personal information.

1. Eligibility

You must be at least 13 years old to create an account. If you have not reached the age of legal majority where you live, a parent or legal guardian must review these Terms with you and permit your use of Limerse.

2. Invitations and accounts

Some content may require an invitation or account. Invitation and sign-in links are credentials: keep them private, open them only on a device you trust, and do not attempt to bypass access restrictions. You are responsible for activity through your account and for keeping access to your email or Google account secure.

Provide accurate information and notify us at hello@limerse.com if you believe your account or invitation has been used without permission. You may request account deletion at the same address.

3. Permitted use

Limerse grants you a limited, personal, non-exclusive, non-transferable, revocable right to use the service for learning and other lawful, non-commercial purposes. Educators may display and link to Limerse in ordinary classroom teaching, subject to these Terms.

You may not:

• Access or use Limerse unlawfully or in a way that infringes another person’s rights.
• Interfere with the service, introduce malicious code, overload infrastructure, or evade security and access controls.
• Probe or access accounts, systems, or data without authorization.
• Use automated extraction to reproduce a substantial part of the service or create a competing content collection.
• Remove ownership notices or misrepresent Limerse content as your own.
• Submit unlawful, harmful, deceptive, infringing, or abusive material.

4. Content and intellectual property

Limerse and its licensors own the service and its text, illustrations, simulations, audio, video, software, designs, and trademarks. These Terms do not transfer ownership to you. You may link to Limerse and make reasonable personal study notes or printouts, but you may not reproduce, publish, sell, license, or distribute substantial portions without written permission or another legal right.

5. Feedback

If you voluntarily submit feedback or suggestions, you give Limerse permission to use them without restriction or payment to improve and operate the service. You retain ownership of any original material you submit. Do not submit confidential information or material you do not have the right to share.

6. Educational information

Limerse is an educational resource, not a substitute for instruction tailored by a qualified teacher or for professional, medical, legal, financial, or safety advice. We work to make the material accurate, but educational content may contain errors or become outdated. You remain responsible for checking important results and following the requirements of your school, instructor, examination provider, or other authority.

7. Third-party services and links

Limerse relies on service providers and may link to third-party websites. Third-party services have their own terms and privacy practices. Limerse is not responsible for third-party content or services that it does not control.

8. Availability and changes

The service is provided on an “as is” and “as available” basis. Features, books, lessons, access limits, and availability may change, and we may suspend or discontinue all or part of Limerse. We do not guarantee uninterrupted operation, permanent storage of progress, or that every error will be corrected.

9. Suspension and termination

We may restrict or terminate access when reasonably necessary to protect the service or others, comply with law, address security risks, or respond to a material violation of these Terms. You may stop using Limerse at any time and may request deletion of your account. Provisions concerning ownership, disclaimers, liability, and disputes survive termination where their nature requires it.

10. Disclaimers and liability

To the fullest extent permitted by law, Limerse disclaims implied warranties, including merchantability, fitness for a particular purpose, and non-infringement. Limerse is not liable for indirect, incidental, special, consequential, exemplary, or punitive damages, or for loss of data, profits, opportunity, or goodwill arising from the service.

To the fullest extent permitted by law, Limerse’s total liability for claims relating to the service will not exceed the amount you paid Limerse for the service during the 12 months before the event giving rise to the claim. Some jurisdictions do not allow certain exclusions or limits, so parts of this section may not apply to you.

11. Governing law

These Terms are governed by the laws of the State of California, without regard to conflict-of-law rules. Nothing in these Terms limits any consumer protection right that cannot lawfully be waived.

12. Changes and contact

We may update these Terms as Limerse changes. We will update the effective date and provide additional notice when required. If a change materially affects your rights, it will apply prospectively. If you do not agree to updated Terms, stop using the service.

Questions, account requests, and legal notices may be sent to hello@limerse.com.
