Terms of Service

These Terms of Service ("Terms") are a binding agreement between you and Nebula AI, LLC ("Nebula AI," "we," "our," or "us"). They govern your access to and use of our website, desktop application, accounts, downloads, subscriptions, AI features, cloud sharing, collaboration features, support, and related services (together, the "Service").

By accessing or using the Service, creating an account, downloading the app, or purchasing a subscription, you agree to these Terms. If you do not agree, do not use the Service. Our Privacy Policy explains how we handle personal information and is incorporated into these Terms by reference.

• You must be at least 13 years old to use the Service. If you are under the age of majority where you live, you may use the Service only with permission from a parent or legal guardian.
• You must provide accurate account information and keep it current.
• You are responsible for maintaining the security of your account, sign-in account, devices, local project files, and any activity under your account.
• You may not share, sell, or transfer your account credentials or use another person's account without permission.
• You must promptly notify us if you suspect unauthorized access to your account.

Nebula Writer is a local-first desktop workspace for writing, documents, research, data, and AI-assisted editing. The Service may include local editing, file management, LaTeX compilation, document import/export, AI assistance, model selection, web and research lookup, Python execution, subscriptions, cloud sharing, collaboration, downloads, updates, and support.

We may add, change, suspend, or discontinue features at any time. Some features may be labeled beta, experimental, preview, or early access. Those features may be less reliable, may change without notice, and may be subject to additional limits.

Subject to these Terms, we grant you a limited, revocable, non-exclusive, non-transferable, non-sublicensable license to install and use the Nebula Writer desktop application for your personal, educational, or internal business purposes.

• You may not copy, rent, lease, sell, sublicense, distribute, host, or make the Service available to third parties except as these Terms allow.
• You may not reverse engineer, decompile, disassemble, or attempt to extract source code except to the extent applicable law allows despite this restriction.
• You may not remove, obscure, or alter proprietary notices.
• Updates may be required for security, compatibility, or continued access to online features.
• Third-party open-source components remain subject to their own licenses.

You keep ownership of the documents, prompts, files, code, data, images, and other content you create, import, upload, share, or submit through the Service ("Your Content"). We do not claim ownership of Your Content.

You grant us a limited license to host, store, transmit, reproduce, display, modify, and process Your Content only as needed to provide, secure, troubleshoot, and improve the Service, comply with law, enforce these Terms, and fulfill your requests. For local-only files, this license applies only when you send content to an online feature or support channel.

You are responsible for Your Content and must have all rights and permissions needed to use it with the Service, including when you send it to AI services, search tools, code execution environments, collaborators, or support.

• AI features are tools to assist your work. They may produce inaccurate, incomplete, unsafe, outdated, offensive, or non-unique output.
• You are responsible for reviewing AI output and deciding whether it is appropriate for your use case before relying on it or publishing it.
• AI output is not legal, medical, financial, tax, academic, engineering, compliance, or other professional advice.
• Do not submit content to AI features unless you have the right to do so and are comfortable with it being processed by online AI services.
• As between you and Nebula AI, LLC, and to the extent permitted by law, you may use output generated for you through the Service. We do not guarantee that output is protectable, exclusive, non-infringing, or free from third-party claims.

If you use shared folders, invite links, cloud documents, collaboration sessions, or similar features, you authorize us to store and process the content and metadata needed to provide those features. People you invite, or whose invites you accept, may be able to view, copy, edit, export, or delete shared content depending on their role and the feature settings.

You are responsible for managing invite links, collaborator permissions, and the content you share. We may remove or restrict shared content if we believe it violates these Terms, applicable law, or the rights of others.

• Paid plans, prices, features, limits, billing periods, and trial terms are shown at checkout or on the pricing page and may vary by plan.
• Subscriptions automatically renew at the end of each billing period unless canceled before renewal.
• By starting a paid subscription or trial that converts to a paid plan, you authorize us and our payment processor to charge your payment method for recurring fees, taxes, and applicable charges.
• You can cancel through the account or billing portal where available, or by contacting us. Cancellation takes effect at the end of the current billing period unless applicable law requires otherwise.
• Except where required by law or expressly stated at checkout, payments are non-refundable and we do not provide credits for partial billing periods.
• If payment fails, we may suspend, downgrade, or terminate paid features after reasonable retries or notice.
• We may change prices or plan features with notice to affected subscribers as required by law. Continued use after the effective date means you accept the change.

You agree not to use the Service to:

• Violate any law, regulation, contract, intellectual property right, privacy right, publicity right, or other right of any person.
• Create, upload, process, or distribute malware, phishing content, exploit code, or material intended to compromise systems or data.
• Harass, abuse, threaten, exploit, or harm another person, including minors.
• Generate or distribute unlawful, defamatory, deceptive, fraudulent, hateful, sexually exploitative, or violent extremist content.
• Bypass usage limits, security measures, authentication, billing, model restrictions, or access controls.
• Scrape, crawl, overload, disrupt, or interfere with the Service or its infrastructure.
• Use the Service for high-risk decisions or regulated professional advice without qualified human review and all legally required safeguards.
• Upload or process sensitive, regulated, or confidential third-party data unless you have the legal right and appropriate safeguards to do so.
• Use the Service in violation of export control, sanctions, or anti-corruption laws.

The Service integrates with or depends on third-party services, including hosting, databases, authentication, payments, AI models, search, research data sources, code execution infrastructure, operating system services, and open-source software. Third-party services are governed by their own terms and privacy notices. We are not responsible for third-party services, content, outages, policies, or changes.

Nebula Writer, including the app, website, design, trademarks, logos, features, documentation, software, and underlying technology, is owned by Nebula AI, LLC or our licensors and is protected by intellectual property and other laws. Except for the limited license granted above, these Terms do not transfer any rights in the Service to you.

If you send suggestions, ideas, feedback, or bug reports, you grant us a perpetual, irrevocable, worldwide, royalty-free license to use them without restriction or compensation.

If you believe content available through the Service infringes your intellectual property rights, contact us at admin@nebulawriter.com with enough detail for us to investigate, including identification of the work, location of the allegedly infringing material, your contact information, and a statement that you believe the use is unauthorized.

You may stop using the Service at any time. We may suspend or terminate your access to the Service, remove content, or downgrade features if we reasonably believe you have violated these Terms, created risk for us or others, failed to pay fees, or used the Service unlawfully or abusively.

After termination, your right to use the Service ends. Sections that by their nature should survive termination will survive, including ownership, payment obligations, disclaimers, limitation of liability, indemnification, dispute terms, and general provisions.

TO THE MAXIMUM EXTENT PERMITTED BY LAW, THE SERVICE IS PROVIDED "AS IS" AND "AS AVAILABLE" WITHOUT WARRANTIES OF ANY KIND, WHETHER EXPRESS, IMPLIED, OR STATUTORY, INCLUDING IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, TITLE, NON-INFRINGEMENT, QUIET ENJOYMENT, ACCURACY, AVAILABILITY, OR RELIABILITY.

We do not warrant that the Service will be uninterrupted, secure, error-free, or that data will not be lost or corrupted. You are responsible for maintaining backups of important files and for independently verifying outputs, citations, calculations, compilations, exports, and AI-assisted work.

TO THE MAXIMUM EXTENT PERMITTED BY LAW, NEBULA AI, LLC AND ITS AFFILIATES, OFFICERS, EMPLOYEES, AGENTS, LICENSORS, AND SERVICE PROVIDERS WILL NOT BE LIABLE FOR INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR FOR LOST PROFITS, LOST REVENUE, LOST DATA, BUSINESS INTERRUPTION, GOODWILL, OR COST OF SUBSTITUTE SERVICES, ARISING FROM OR RELATED TO THE SERVICE OR THESE TERMS.

TO THE MAXIMUM EXTENT PERMITTED BY LAW, OUR TOTAL LIABILITY FOR ALL CLAIMS ARISING FROM OR RELATED TO THE SERVICE OR THESE TERMS WILL NOT EXCEED THE GREATER OF $100 OR THE AMOUNT YOU PAID TO NEBULA WRITER FOR THE SERVICE IN THE 12 MONTHS BEFORE THE EVENT GIVING RISE TO THE CLAIM.

To the extent permitted by law, you will defend, indemnify, and hold harmless Nebula AI, LLC and its affiliates, officers, employees, agents, licensors, and service vendors from and against claims, damages, liabilities, losses, costs, and expenses (including reasonable attorneys' fees) arising from or related to Your Content, your use of the Service, your violation of these Terms, your violation of law, or your infringement or misappropriation of any rights.

These Terms are governed by the laws of the State of Texas and applicable federal law, without regard to conflict-of-law rules. Except where applicable law requires otherwise, you and Nebula AI, LLC consent to the exclusive jurisdiction and venue of the state and federal courts located in Texas for disputes arising from or related to these Terms or the Service.

To the extent permitted by law, claims must be brought only in an individual capacity and not as a plaintiff or class member in any class, collective, consolidated, or representative proceeding.

We may update these Terms from time to time. If we make material changes, we will provide notice by updating this page, changing the "Last updated" date, and where appropriate, notifying you by email or in the Service. Your continued use after the effective date of updated Terms means you accept the updated Terms.

• You may not assign these Terms without our consent. We may assign them in connection with a merger, acquisition, financing, reorganization, sale of assets, or by operation of law.
• If any provision is found unenforceable, the remaining provisions will remain in effect and the unenforceable provision will be modified to the minimum extent necessary to make it enforceable.
• Our failure to enforce a provision is not a waiver of our right to do so later.
• These Terms, together with the Privacy Policy and any checkout or plan-specific terms, are the entire agreement between you and us about the Service.
