Terms of Service

Last updated: October 2, 2026

These Terms of Service ("Terms") govern your use of LunaRabbit Inc.'s products and services. By using our services, you agree to these Terms.

1. Service Description

LunaRabbit Inc. (a Delaware corporation) operates the following products (collectively, the "Services"):

• LunaRabbit Chat — AI chat assistant accessible at lunarabbit.ai and via mobile apps (iOS/Android). Features include conversational AI, web search, financial data retrieval, image generation, deep research, file analysis, and voice input.
• LunaRabbit Office — AI-powered productivity tools for Google Workspace™ and Microsoft Office™. Supported platforms: Google Sheets™, Microsoft Excel™, Microsoft Word™, Microsoft PowerPoint™, and a standalone web editor. Features include AI chat agents, custom functions, and document automation.
• LunaRabbit Code — an AI coding assistant provided as a VS Code extension with a local engine and CLI (lunarabbit-engine).
• LunaRabbit Drive — file storage, sharing, and version management at drive.lunarabbit.ai.

Where a clause applies only to a specific product, that product is named explicitly.

Geographic availability. The Services are offered to users in South Korea, the United States, and other supported regions. They are not directed to, or intended for, residents of the European Economic Area (EEA) or the United Kingdom, and our mobile apps are not distributed in those regions. We do not target, market to, or monitor users in the EEA or UK.

2. Beta Services

Certain features or platforms may be designated as "Beta," "Preview," or "Early Access" (collectively, "Beta Services"). By using Beta Services, you acknowledge and agree that:

• Beta Services are provided for evaluation purposes and may contain bugs, errors, or incomplete functionality.
• We may modify, suspend, or discontinue any Beta Service or feature at any time without prior notice.
• Data created or stored during the Beta period may be deleted or reset without advance notice. You are responsible for maintaining your own backups.
• We make no guarantees regarding uptime, availability, or service level agreements (SLAs) for Beta Services.
• Pricing, credit allocations, and plan structures are subject to change before or upon general availability.
• We will make reasonable efforts to notify users when a Beta Service transitions to general availability or is discontinued.

Beta Services are provided "as is" and "as available" without warranty of any kind, and the limitation of liability provisions in Section 10 apply with full force to Beta Services.

3. Account Registration

LunaRabbit Chat requires a free account. You must sign in or create an account to use the service; there is no anonymous (non-logged-in) access.

To use our services, you must:

• Sign in with a valid Google or Microsoft account, or register with your email address
• Provide accurate account information
• Be at least 18 years of age (or the minimum age required by applicable law in your jurisdiction)
• Keep your account credentials secure

You are responsible for all activity that occurs under your account.

4. Free Plan

All Office users receive a monthly AI usage allowance at no cost. The allowance resets periodically and does not roll over. The free plan includes access to AI custom functions in Sprinter mode. No credit card is required.

Beta status: The Services are currently provided as a Beta Service. By using the Services, you accept the Beta Services terms in Section 2. Paid plans are available at pricing.lunarabbit.ai.

We reserve the right to modify the free plan limits, introduce paid plans, or change features at any time with reasonable notice.

Chat Free Plan

All Chat users receive a daily AI usage allowance at no cost. The allowance resets daily and does not roll over. The free plan includes access to Basic mode with web search, Deep Research, and image generation capabilities. No credit card is required.

A LunaRabbit account is required to use LunaRabbit Chat. We do not offer anonymous (non-logged-in) access.

Model improvement (account-level opt-in): A single choice applies to all LunaRabbit products tied to your account, including Chat conversations, Office documents and spreadsheets, and coding content. Google user data received through Google APIs (such as Google Sheets and Gmail content) is excluded from model improvement regardless of this choice. The default is off; eligible content may be used for model improvement only if you opt in via the consent modal or Settings, and you can withdraw at any time. We do not currently collect, retain, or use this content for model training or improvement; opting in is advance authorization for a feature that is not yet active. See our Privacy Policy for details.

LunaRabbit Code

You must sign in to your LunaRabbit account to use LunaRabbit Code. AI-generated code and commands may be incorrect or unsafe; review them before use. You are responsible for the results of commands and file changes that you approve and execute on your own PC. LunaRabbit Code usage draws from the credit pool shared with other LunaRabbit Services and follows the credit and billing conditions of your existing plan.

LunaRabbit Drive

You must sign in to your LunaRabbit account to use LunaRabbit Drive; WebDAV access requires a separate app password. Drive lets you store files, manage versions, and share files or folders with named people or through links. When you share a file or folder, recipients receive access according to the permissions you set, including editing access to a shared folder when you grant it. You are responsible for choosing recipients and managing those permissions. Storage capacity and retention follow your plan's rules as described in Section 7-2. If you use another LunaRabbit product to create AI content stored in Drive, that product's credit and billing conditions apply; Drive itself does not call AI models for inference.

5. Refund Policy

Refunds and subscription cancellations are governed by our Refund Policy, which forms part of these Terms by reference. In summary:

• Consumers in South Korea have a 7-day cooling-off period for unused digital content.
• All customers are eligible for a 14-day goodwill refund window, subject to the conditions in the Refund Policy.
• Payments are processed through a third-party payment processor that acts as our Merchant of Record and handles VAT, GST, and sales-tax compliance on our behalf. The processor is identified at checkout.

6. Acceptable Use

You agree to comply with our Acceptable Use Policy, which is incorporated into these Terms by reference. In summary, you agree not to use our services to:

• Violate any applicable laws or regulations.
• Generate illegal, harmful, or abusive content — including but not limited to: child sexual abuse material, content intended to incite violence or discrimination against protected groups, content used in connection with fraud or identity theft, content designed to bypass lawful content-moderation in other platforms, or material violating sanctions / export-control regimes.
• Attempt to reverse-engineer, decompile, extract, or redistribute our software or system internals.
• Use automated tools to scrape or bulk-access the Services beyond reasonable use. Attempts to evade rate limits or other protective controls are prohibited.
• Impersonate others or provide false information during account registration.
• Interfere with or disrupt the Services, other users, or the underlying infrastructure, including denial-of-service attempts.
• Use the Services to develop a substantially competing AI product where model outputs are used as training data (output-capture for model cloning is expressly prohibited).

We reserve the right to suspend or terminate accounts that violate these terms, with or without prior notice depending on severity.

Additional Chat-specific rules: You agree not to use LunaRabbit Chat to circumvent rate limits via automated means (VPN rotation, cookie clearing scripts, etc.), or to use the service as a backend for other applications without prior written agreement.

7. Intellectual Property

Our Property

LunaRabbit and all associated trademarks, logos, and service marks are our property. The underlying technology, AI models, and software are protected by intellectual property laws.

Your Content

You retain full ownership of your documents and data. We do not claim any rights to the content you process through our services. AI-generated outputs (formulas, text, etc.) belong to you.

7-2. File Storage and Uploaded Content

The Services include file upload, a library (storage of uploaded files and AI-generated outputs), and document analysis features. Please review the following before uploading or storing files.

Rights Warranty and User Responsibility

• You warrant that you hold all necessary rights (including copyright, trademark, and other intellectual property rights) to any content you upload, store, or share. You agree not to upload content that infringes the rights of any third party.
• We do not pre-screen files uploaded by users. You are solely responsible for all files you upload or store.
• Uploaded content is subject to the Acceptable Use Policy in Section 6. In particular, you must not upload or store harmful code such as malware or viruses, material that violates the privacy or confidential information of others, or any content that violates applicable law.

Access and Security

Content you upload is protected and is shared with others only when you explicitly share it. We may access your content only in the following cases: (i) as necessary to provide the Services (such as file format validation, thumbnail generation, and AI analysis); (ii) as permitted by these Terms or our Privacy Policy; (iii) as required by law, regulation, or valid legal order; or (iv) as needed to respond to emergencies such as security incidents.

Retention, Limits, and Deletion

• Storage capacity and retention periods vary by plan and are described within the Services. When a retention period expires or your storage limit is exceeded, older files may be deleted first.
• When you delete a file or conversation, linked stored files are deleted with it. Upon account deletion, stored content is irrecoverably deleted after a 30-day grace period.
• We strive for storage availability but do not warrant that storage will be uninterrupted or error-free. Please maintain your own backups of important files.
• We may impose reasonable limits on storage and may take action against accounts that exceed those limits or violate this section.

Our liability in connection with file storage features is subject to Section 10 (Limitation of Liability) and Section 11 (Indemnification).

8. AI Output Disclaimer

AI-generated results (formulas, text, data analysis) are provided "as is." While we strive for accuracy, AI outputs may contain errors. You are responsible for reviewing and verifying all AI-generated content before use, especially for critical business decisions.

Advance notice that the Services run on AI. LunaRabbit Chat, LunaRabbit Office, and LunaRabbit Code are operated on the basis of generative artificial intelligence. Text, formulas, code, images, video, and audio you receive from those products are produced by AI models. LunaRabbit Drive may store or display AI-generated files from those products, but Drive does not itself call AI models for inference.

Labeling of generated media. Images and video created by our generation tools are presented on cards labeled "Generated image" and "Generated video"; read-aloud and audio-overview features are labeled as such in the interface. We do not embed watermarks or machine-readable provenance data inside the files themselves. You acknowledge that outputs from our AI generation features are AI-generated, and if you republish them outside the Services you are responsible for disclosing that fact.

9. Service Availability

We aim for 99.9% uptime but do not guarantee uninterrupted service. We may perform maintenance, updates, or experience outages. We will make reasonable efforts to notify you of planned downtime in advance.

10. Limitation of Liability

To the maximum extent permitted by law:

• Our services are provided "AS IS" and "AS AVAILABLE" without warranties of any kind, whether express, implied, or statutory, including but not limited to implied warranties of merchantability, fitness for a particular purpose, title, and non-infringement.
• We are not liable for any indirect, incidental, or consequential damages.
• Our total liability is limited to the amount you paid us in the 12 months preceding the claim.
• We are not responsible for errors in AI-generated content or any decisions made based on such content.
• During the Beta period, service interruptions, data loss, feature changes, and pricing adjustments may occur without prior notice. Your use of Beta Services is at your sole risk.

11. Indemnification

You agree to indemnify, defend, and hold harmless LunaRabbit Inc., its officers, directors, employees, and agents from any claims, damages, losses, liabilities, and expenses (including reasonable attorneys' fees) arising out of or related to: (a) your use of the Services; (b) your violation of these Terms or the Acceptable Use Policy; (c) your violation of any third-party rights, including intellectual property rights; or (d) any content you submit through the Services.

12. Force Majeure

Neither party shall be liable for any failure or delay in performing its obligations under these Terms where such failure or delay results from circumstances beyond the reasonable control of that party, including but not limited to: natural disasters, pandemic, war, terrorism, riots, embargoes, acts of civil or military authorities, fire, floods, accidents, strikes, infrastructure failures, internet service provider failures, or actions of third-party AI model providers. The affected party shall use reasonable efforts to mitigate the impact and resume performance as soon as practicable.

13. Termination

We may suspend or terminate your account if you violate these Terms. You may delete your account at any time by contacting us. Upon termination, your data will be deleted in accordance with our Privacy Policy.

14. Changes to Terms

We may update these Terms from time to time. We will provide at least thirty (30) days' advance notice of significant changes via email or a prominent notice on our website. Continued use of our services after changes constitutes acceptance of the updated Terms.

15. Governing Law

These Terms are governed by and construed in accordance with the laws of the State of Delaware, United States, without regard to its conflict of law provisions.

16. Dispute Resolution

Informal Resolution

Before filing any formal proceeding, you agree to try to resolve any dispute informally by contacting us at [email protected]. We will try to resolve the dispute within 30 days.

Binding Arbitration

If we cannot resolve a dispute informally, any dispute, claim, or controversy arising out of or relating to these Terms or the Services (including their formation, performance, or breach) shall be settled by binding arbitration administered by the American Arbitration Association (AAA) under its Commercial Arbitration Rules. The arbitration will be conducted in English in the State of Delaware, and the arbitrator's decision will be final and binding.

Class Action Waiver

You and LunaRabbit agree that any dispute resolution proceedings will be conducted only on an individual basis and not in a class, consolidated, or representative action. If this class action waiver is found to be unenforceable, then the entirety of this arbitration provision shall be null and void.

Small Claims Exception

Notwithstanding the above, either party may bring an individual action in small claims court for disputes within the court's jurisdiction.

Consumer Protection Carve-Out

If you are a consumer resident in South Korea, the binding arbitration and class action waiver provisions above do not apply to you. Instead, any dispute shall be resolved in the courts of your country of residence, in accordance with the mandatory consumer protection laws of that jurisdiction, including your rights before Korea's Consumer Dispute Settlement Commission (소비자분쟁조정위원회).

Opt-Out

You may opt out of this arbitration provision by sending written notice to [email protected] within 30 days of first accepting these Terms. If you opt out, disputes will be resolved through the state or federal courts located in the State of Delaware.

17. Severability

If any provision of these Terms is found to be invalid, illegal, or unenforceable by a court of competent jurisdiction, such invalidity shall not affect the validity of the remaining provisions, which shall remain in full force and effect.

18. Entire Agreement

These Terms, together with our Privacy Policy, Cookie Policy, Acceptable Use Policy, and Refund Policy, constitute the entire agreement between you and LunaRabbit regarding the use of our Services, and supersede all prior agreements, understandings, and communications, whether written or oral.

19. Assignment

You may not assign or transfer these Terms or your rights under these Terms, in whole or in part, without our prior written consent. We may assign these Terms at any time without notice, including in connection with a merger, acquisition, or sale of assets. Any purported assignment in violation of this section shall be void.

20. Waiver

No waiver of any provision of these Terms shall be deemed a further or continuing waiver of such provision or any other provision. Our failure to assert any right or provision under these Terms shall not constitute a waiver of such right or provision.
