Terms of Service

Terms of Service

These Terms of Service apply to your use of just4o.chat and any associated websites, applications, and features we make available to individual users (together, the "Services"). The Services are operated by LK Digital Solutions LLC (the "Company"). These Terms form a binding agreement between you and the Company regarding your use of just4o.chat.

By creating an account, accessing, or using the Services, you agree to these Terms. If you do not agree, do not use the Services.

Our Privacy Policy explains how we collect and use personal information. Our Safety page explains our moderation and risk approach. Our Why We Do This page explains why we take certain safety and legal-risk positions.

Registration and Access

Minimum age. You must be at least eighteen (18) years old to use the Services. By creating an account or using the Services, you represent and warrant that you are 18 or older.

Registration. You must provide accurate and complete information to create an account. You may not share your credentials or make your account available to anyone else. You are responsible for all activity that occurs under your account and for promptly notifying us of unauthorized use.

Adult-use requirement. Because just4o.chat includes long-term memory and access to many AI models, the Services are intended only for adults who can evaluate outputs and accept the associated risks.

Using Our Services

Subject to your compliance with these Terms, you may access and use the Services. In using the Services, you must comply with applicable law and any policies, safety rules, feature restrictions, or product rules we make available to you.

You may not use the Services to:

• Violate the law or anyone else's rights
• Exploit, sexualize, or endanger minors
• Promote self-harm, violence, fraud, stalking, harassment, or other harmful activity
• Develop, facilitate, or meaningfully assist malware, phishing, credential theft, unauthorized access, or other abusive security activity
• Interfere with, disrupt, reverse engineer, scrape, or bypass limits on the Services
• Use automated means to access the Services in a manner that imposes unreasonable load or circumvents intended controls
• Misrepresent AI output as human-generated where that would be deceptive or unlawful
• Use the Services in a way that creates unreasonable safety, legal, or security risk

We may use automated systems, filters, classifiers, heuristics, and human review to detect abuse, safety concerns, or policy violations. We reserve the right to review, restrict, block, refuse, filter, disable, or remove Content, prompts, model access, features, or accounts that violate these Terms, our policies, or our moderation heuristics, or that otherwise create safety, legal, reputational, or operational risk.

Our Services may include or rely on third-party software, models, products, or services. Those third parties are subject to their own terms, and we are not responsible for them.

Some models are delivered through third-party inference hosts. For example, GPT OSS 120B Fast is an OpenAI model served through Cerebras, and GLM 4.7 Fast is a Z.ai model served through Cerebras. Other open-source models may be served through providers such as Fireworks AI. When you choose one of those models, your prompts and outputs are processed by the applicable provider under that provider's terms.

Content

You may provide input to the Services ("Input"), and receive output from the Services ("Output"). Input and Output are collectively "Content."

You are responsible for your Content, including making sure you have the rights needed to submit it and that it complies with law and these Terms.

As between you and us, you retain your rights in Input, and to the extent permitted by law, you own your Output. You grant us the rights reasonably necessary to host, store, process, transmit, display, reproduce, moderate, back up, secure, and improve the Services using your Content.

Due to the nature of AI, Output may not be unique, and other users may receive similar or identical output.

The Services are not intended as an NSFW platform. As a practical disclaimer, because Output is generated probabilistically and is influenced by your Input, conversation context, and third-party model behavior, sexual, explicit, or otherwise adult content may still appear, including while Safety Mode is enabled. Safety Mode is intended to reduce that risk, not eliminate it entirely, and we do not guarantee that every response will remain within any particular tone or boundary you expected.

Accuracy and Risk

Artificial intelligence is probabilistic and can be inaccurate. Output may be incomplete, incorrect, misleading, biased, manipulative, offensive, sexually explicit, emotionally intense, or otherwise unsafe.

When you use the Services, you understand and agree that:

• Output may not always be accurate
• You will not rely on Output as a sole source of truth or as a substitute for professional advice
• You must evaluate Output for accuracy and appropriateness before using or sharing it
• You must use human review where the stakes are personal, professional, financial, medical, legal, or safety-related
• You use any Output, decisions, and downstream consequences at your own risk
• You will not use Output about a real person to make or support decisions about employment, housing, credit, lending, insurance, education, healthcare, legal status, professional licensing, or other high-impact matters

just4o.chat is not a doctor, therapist, lawyer, financial advisor, crisis line, or emergency service. If you are in crisis or need urgent help, do not rely on the Services.

Paid Accounts, Billing, and Credits

Some features require payment. If you purchase a subscription, credits, or other paid feature, you must provide complete and accurate billing information and authorize the applicable charges, including any recurring charges disclosed at checkout.

Billing intervals, included features, usage limits, and renewal terms will be presented at the time of purchase. Unless we say otherwise at purchase, paid subscriptions renew automatically until canceled. You may cancel before the next renewal to avoid future charges, and cancellation will ordinarily take effect at the end of the current paid period.

Fees may be subject to taxes. If a payment fails or a charge is reversed, we may suspend, downgrade, or limit access to paid features until payment is successfully completed.

Availability of the Services, checkout, subscriptions, credits, and certain paid or unpaid features may be limited, disabled, or unavailable in certain countries, regions, or jurisdictions for legal, tax, sanctions, payment, fraud, compliance, provider, or operational reasons. These regional restrictions may change over time, including as VAT rules, local tax obligations, AI or chatbot regulations, payment provider requirements, or other applicable laws, regulations, or business conditions evolve.

Unless required by law, payments are non-refundable, and we do not provide refunds or credits for partially used subscription periods, unused usage allotments, or unused prepaid balances.

If we offer credits, usage balances, or other prepaid entitlements, they are licenses to access certain Service features, have no cash value, are non-transferable, and may be modified, revoked, or discontinued as part of the Services to the extent permitted by law.

We may change prices, plans, usage limits, or available features from time to time. If a subscription price increases, we will make reasonable efforts to provide notice before the increase takes effect.

Intellectual Property and Feedback

Except for your Content and any third-party materials, the Services, including the software, interface, design, compilations, text, graphics, branding, and related intellectual property, are owned by or licensed to the Company and are protected by applicable law.

Except as expressly permitted by these Terms or applicable law, you may not copy, modify, distribute, sell, lease, sublicense, publicly display, or create derivative works from the Services, or use our branding in a way that suggests endorsement, affiliation, or sponsorship without permission.

If you provide feedback, ideas, or suggestions about the Services, you grant us a perpetual, irrevocable, worldwide, royalty-free right to use them for any lawful purpose without compensation to you.

Privacy

Your use of the Services is subject to our Privacy Policy, which describes how we collect, use, disclose, and protect personal information.

Termination and Suspension

You may stop using the Services at any time. We may suspend, restrict, or terminate your access, remove Content, or disable features if we determine that:

• You breached these Terms or our policies
• We must do so to comply with law or a valid legal request
• Your use of the Services creates risk or harm to us, our users, third parties, or the public
• You misrepresented your eligibility, including the adult-use requirement
• Your account has been inactive for an extended period and we decide to close it

Upon termination, your right to use the Services ends immediately. We may retain, delete, or anonymize account information and Content as permitted or required by law, our operational needs, and our Privacy Policy. Sections that by their nature should survive termination will survive, including sections concerning payment obligations, content rights, intellectual property, disclaimers, limitations of liability, indemnity, disputes, and general legal terms.

Disclaimer of Warranties

THE SERVICES ARE PROVIDED "AS IS" AND "AS AVAILABLE." TO THE MAXIMUM EXTENT PERMITTED BY LAW, WE AND OUR AFFILIATES, LICENSORS, AND SERVICE PROVIDERS DISCLAIM ALL WARRANTIES, WHETHER EXPRESS, IMPLIED, STATUTORY, OR OTHERWISE, INCLUDING WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, NON-INFRINGEMENT, QUIET ENJOYMENT, ACCURACY, AVAILABILITY, AND SECURITY.

We do not warrant that the Services will be uninterrupted, secure, error free, accurate, or free from data loss. We do not warrant that any Output will be safe, reliable, lawful in your jurisdiction, or fit for your use case.

Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW, NEITHER WE NOR OUR AFFILIATES, LICENSORS, OR SERVICE PROVIDERS WILL BE LIABLE FOR ANY INDIRECT, INCIDENTAL, SPECIAL, CONSEQUENTIAL, EXEMPLARY, OR PUNITIVE DAMAGES, OR FOR ANY LOSS OF PROFITS, REVENUE, GOODWILL, DATA, USE, BUSINESS OPPORTUNITY, OR PERSONAL DISTRESS, ARISING OUT OF OR RELATING TO THE SERVICES OR THESE TERMS.

TO THE MAXIMUM EXTENT PERMITTED BY LAW, OUR AGGREGATE LIABILITY FOR ALL CLAIMS ARISING OUT OF OR RELATING TO THE SERVICES OR THESE TERMS WILL NOT EXCEED THE GREATER OF: (A) THE AMOUNT YOU PAID FOR THE RELEVANT SERVICE IN THE 12 MONTHS BEFORE THE CLAIM AROSE, OR (B) ONE HUNDRED U.S. DOLLARS (US$100).

Some jurisdictions do not allow certain disclaimers or limitations. In those jurisdictions, these Terms apply only to the maximum extent permitted by law.

Indemnity

To the maximum extent permitted by law, if your use of the Services, your Content, or your violation of these Terms causes a third-party claim against us, you will indemnify and hold harmless the Company, its operators, affiliates, and personnel from the resulting costs, losses, liabilities, and expenses, including reasonable attorneys' fees.

Restricted Use and Export Compliance

You may not use the Services if doing so would violate applicable law, including applicable sanctions, export-control, or trade-compliance laws. You represent and warrant that you are not located in, resident in, or ordinarily providing access to the Services from a jurisdiction subject to comprehensive U.S. sanctions, and that you are not a person or entity with whom U.S. persons are generally prohibited from dealing.

Disputes, Governing Law, and Venue

We want to resolve concerns directly, efficiently, and in good faith before either side turns to formal legal process. If you have a dispute, claim, or concern arising out of or relating to the Services or these Terms, you agree to contact us first at just4ochat@gmail.com and give us a reasonable opportunity to try to resolve it informally.

Your notice should include your name, the email address associated with your account, a description of the issue, any relevant dates or supporting facts, and the specific resolution you are requesting. We may reply by email and may ask for additional information reasonably necessary to understand the issue.

If either side has a legal dispute with the other, both sides agree to make a good-faith effort to resolve it informally for at least sixty (60) days after written notice is sent to just4ochat@gmail.com before filing a lawsuit or other formal proceeding, unless applicable law does not allow such a requirement.

These Terms and any dispute arising out of or relating to them or the Services are governed by the laws of the State of New York, without regard to conflict-of-laws rules. To the extent a dispute is permitted to proceed in court, you and the Company agree to the exclusive jurisdiction of the state or federal courts located in New York County, New York, except that either party may bring an eligible claim in small claims court and either party may seek temporary or urgent equitable relief where genuinely necessary to prevent misuse, abuse, infringement, unauthorized access, or immediate harm.

Copyright Complaints

If you believe content made available through the Services infringes your copyright or other intellectual property rights, contact us at just4ochat@gmail.com with enough detail for us to review the claim, including your contact information, a description of the work you believe is infringed, a description of the allegedly infringing material and where it appears, and a statement that you have a good-faith belief the disputed use is unauthorized.

General Terms

We may update these Terms or the Services from time to time, including for legal, safety, security, operational, or product reasons. We may provide notice of material updates by email or in-product notification. Some updates may require you to review and re-accept the revised Terms before continuing to use the Services.

We are not liable for delays or failures caused by events beyond our reasonable control, including infrastructure outages, cyberattacks, labor disputes, acts of government, natural disasters, or failures of suppliers or service providers.

You may not assign or transfer these Terms without our prior written consent. We may assign these Terms in connection with a merger, acquisition, reorganization, sale of assets, or by operation of law.

If any provision of these Terms is found unenforceable, that provision will be enforced to the maximum extent permitted and the remainder of the Terms will remain in effect. Our failure to enforce a provision is not a waiver of our right to do so later.

These Terms, together with any policies or rules expressly incorporated by reference, constitute the entire agreement between you and the Company regarding the Services and supersede prior or contemporaneous understandings on that subject.
