Terms of Service
Last Updated: February 20, 2026
Parental Supervision Required
This service utilizes Artificial Intelligence. While we implement strict safety filters, AI behavior can be unpredictable.
We strongly recommend that parents or guardians supervise their children while using Lumisia.
Language Precedence: These Terms of Service are originally written in Japanese. In the event of any discrepancy between the Japanese version and this English translation, the Japanese version shall prevail.
1. Acceptance of Terms
By accessing or using Lumisia ("the Service"), operated by EISOL LLC ("Company"), you agree to be bound by these Terms of Service. If you are a parent or guardian, you agree to these terms on behalf of your child.
For information on how we handle personal data, please review our Privacy Policy, which forms an integral part of these Terms.
2. AI Generated Content
- Nature of AI: The Service uses AI to generate stories and images. The output is generated automatically and Lumisia cannot guarantee its accuracy or suitability for all purposes.
- Safety: We strive to filter harmful content using industry-standard safety mechanisms. However, no filter is 100% perfect.
- Reporting: If you encounter inappropriate content, please use the in-app reporting tools immediately.
- User Responsibility: If AI-generated content infringes upon a third party's rights due to your intentional actions (e.g., deliberately entering prompts to mimic specific copyrighted works), you shall be responsible for resolving such matters.
3. Intellectual Property Rights
Your Creations
You retain ownership of the stories and characters you create using Lumisia, to the extent permitted by applicable law.
Due to the nature of AI, similar content may be generated for other users. You acknowledge that you may not be able to claim exclusive or proprietary rights over your generated content.
Note: The legal treatment of copyright in AI-generated content varies by jurisdiction and may not be fully established. In some jurisdictions, AI-generated content may not qualify for copyright protection.
Company Materials
Intellectual property rights in the Company's existing materials (templates, characters, programs, etc.) contained within generated content remain with the Company.
Personal Use
You may freely use your generated content for personal, non-commercial purposes (e.g., printing at home, posting on personal social media or blogs).
License to Us
By using the Service, you grant Lumisia a worldwide, non-exclusive, royalty-free license (including the right to sublicense to our service providers) to host, store, display, and use your content for the following purposes:
- Service Operation: To provide the Service, including storage, processing, and display of content
- Service Improvement: To analyze usage patterns and improve quality. Your content and prompts will NOT be used for AI model training (re-training).
- Marketing: Only for content you have made "public" within the Service
Moral Rights
You agree not to assert moral rights against the Company or its authorized third parties for use within the scope described above (including modifications such as resizing or format conversion).
4. Account Management & Parental Ownership
All accounts must be created and owned by a parent, legal guardian, or an adult over the age of majority in your jurisdiction. The Service is not intended to be used independently by children. Children may only access the Service as an authorized profile under a parent or guardian's account, with direct supervision.
You are responsible for maintaining the security of your account credentials (email, password, or other authentication information). You must not share, lend, transfer, or sell your account to any third party.
The Company shall not be liable for any damage arising from inadequate management or unauthorized use of account credentials, or from unsupervised access to the Service by a minor.
5. Billing and Payment
Prices for paid plans are as displayed on the subscription page (inclusive of applicable taxes).
Auto-Renewal: Subscriptions (monthly or annual) automatically renew at the end of each billing period unless you cancel.
Cancellation: You may cancel at any time from the App Settings before the next renewal date. After cancellation, you retain access until the end of your current billing period.
Refunds & Right of Withdrawal: Due to the immediate delivery of digital content, by subscribing, you expressly agree to the immediate performance of the contract and acknowledge that you will lose your right of withdrawal (such as the EU/UK 14-day cooling-off period) once the digital content is provided. Refunds are generally not available after payment is processed, except where expressly required by applicable consumer law.
Payment processing is handled by Stripe. We do not store or directly handle your credit card information.
6. User Conduct
You agree NOT to:
- Attempt to generate content that is violent, sexual, hateful, or illegal.
- Infringe upon the intellectual property, portrait, or privacy rights of others.
- Intentionally mimic the style of specific creators or artists in a manner that harms their rights or interests.
- Place excessive load on our servers, or attempt to reverse engineer the Service.
- Use content generated by the Service as training data for other AI models.
- Use the Service for any commercial purpose without our express written consent.
7. Disclaimer & Limitation of Liability
THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE". LUMISIA DISCLAIMS ALL WARRANTIES, WHETHER EXPRESS OR IMPLIED, INCLUDING THE WARRANTIES OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE.
Limitation of Liability: To the maximum extent permitted by applicable law, the Company's total liability to you for any damages arising from the Service shall not exceed the amount of fees paid by you in the month in which the damage occurred. For free plan users, this cap is equivalent to one month's fee of the monthly subscription plan.
Where applicable consumer protection laws provide additional protections that cannot be waived, those protections shall apply notwithstanding the above limitations.
8. Service Modifications & Interruption
The Company may modify, suspend, or terminate the Service with reasonable prior notice (generally 30 days). Exceptions include emergency security fixes, force majeure events, regulatory changes, or urgent system maintenance.
9. Modification of Terms
The Company may modify these Terms when: (a) the modification is in the general interest of users; or (b) the modification is reasonable considering the purpose of the agreement, the necessity for the change, and the appropriateness of the modified terms.
We will notify you of any changes at least 14 days before the effective date via in-app notice or email. Continued use of the Service after the effective date constitutes acceptance of the modified Terms.
10. Force Majeure
The Company shall not be liable for any failure to perform its obligations under these Terms if such failure results from events beyond its reasonable control, including but not limited to: natural disasters, wars, terrorism, epidemics, government actions, labor disputes, failures of AI model providers or third-party services, power outages, or telecommunications failures.
11. Exclusion of Anti-Social Forces
Users represent and warrant that they are not, and are not affiliated with, any organized crime group, criminal enterprise, or other anti-social force as defined under applicable Japanese law. The Company reserves the right to immediately terminate the account of any user found to be in violation of this provision without prior notice.
12. Account Deletion & Data Processing
You may request deletion of your account at any time through the Settings page or by emailing privacy@lumisia.world.
Upon receiving your deletion request, we will process your data as follows:
- Account and personal data: Deleted within 30 days of request receipt.
- Generated content (stories, images): Made private immediately and permanently deleted within 30 days.
- Payment information: Managed separately through Stripe in accordance with their terms.
- Backup deletion: Removed from backup systems within a technically reasonable period (up to 90 days).
The license granted to the Company under Section 3 terminates upon completion of account deletion. However, the Company is not responsible for retrieving content previously shared or saved by third parties.
In the event of service termination, the Company will provide a reasonable period (minimum 30 days) for users to download their generated content and will endeavor to provide data export tools.
13. Governing Law & Jurisdiction
These Terms shall be governed by the laws of Japan, without regard to its conflict of law provisions. Any disputes arising from the Service shall be subject to the exclusive jurisdiction of the Tokyo District Court as the court of first instance.
Notwithstanding the above, where the mandatory consumer protection laws of your country of residence provide additional protections that cannot be waived, such mandatory provisions shall prevail over this clause.
14. Copyright Complaints (DMCA Policy)
The Company respects the intellectual property rights of others. If you believe your copyrighted work has been infringed by content generated or hosted on our Service, please submit a notice to our Designated Copyright Agent at legal@lumisia.world.
Your notice must comply with the requirements of the Digital Millennium Copyright Act (DMCA) and include: (a) your physical or electronic signature; (b) identification of the copyrighted work claimed to have been infringed; (c) identification of the material to be removed and its location; (d) your contact information; (e) a good faith statement that the use is unauthorized; and (f) a statement under penalty of perjury that the information is accurate and you are the copyright owner or authorized to act on their behalf.
Users who deliberately bypass safety filters to generate and publicly disseminate copyright-infringing material will have their accounts immediately terminated.
15. Dispute Resolution & Class Action Waiver (For US Residents)
If you reside in the United States, you and the Company agree that any dispute or claim arising out of or relating to these Terms or the Service will be resolved by binding arbitration, rather than in court, except that you may assert claims in small claims court if your claims qualify.
You and the company agree that any dispute resolution proceedings will be conducted only on an individual basis and not in a class, consolidated, or representative action. If for any reason a claim proceeds in court rather than in arbitration, we each waive any right to a jury trial.
