1. ACCEPTANCE OF TERMS By accessing, browsing, or using keep4o.chat ("Service"), you ("User," "you," or "your") acknowledge that you have read, understood, and agree to be bound by these Terms of Service ("Terms"). If you do not agree to these Terms in their entirety, you must immediately cease all use of the Service and terminate your account, if applicable. These Terms constitute a legally binding agreement between you and Keep4o ("we," "us," or "our"). Your continued use of the Service following any modifications to these Terms shall constitute your acceptance of such modifications.
1.1 EXPLICIT CONSENT AT REGISTRATION. By creating an account and checking the "I have read and agree to the Terms of Service and Privacy Policy" checkbox during registration, you provide explicit, informed, and affirmative consent to these Terms and the Privacy Policy. You may not create an account or use the Service without providing this consent. This affirmative action constitutes your electronic signature and has the same legal effect as a handwritten signature.
THESE TERMS CONTAIN IMPORTANT LEGAL OBLIGATIONS AND LIMITATIONS OF LIABILITY. BY USING THIS SERVICE, YOU EXPRESSLY ACKNOWLEDGE AND AGREE THAT YOU HAVE READ, UNDERSTOOD, AND ACCEPT ALL TERMS, INCLUDING THE ASSUMPTION OF ALL RISKS ASSOCIATED WITH AI MODEL USAGE.
2. USER RESPONSIBILITY AND ASSUMPTION OF RISK 2.1 ADULT USER STATUS AND CAPACITY. You represent and warrant that you are at least eighteen (18) years of age (or the age of majority in your jurisdiction) and possess full legal capacity to enter into binding agreements. The Service treats all users as adults with full decision-making capacity. You bear sole and exclusive responsibility for all consequences arising from your use of the Service.
2.2 MENTAL HEALTH AND PSYCHOLOGICAL WELL-BEING. You expressly acknowledge and accept full responsibility for your own mental health, emotional well-being, and psychological state, including any psychological effects arising from your interactions with AI models provided through the Service, including but not limited to GPT-4o and any other models made available. The Service does not provide any medical, psychological, psychiatric, therapeutic, counseling, or mental health services. All interactions with AI models occur entirely at your own risk and discretion.
2.3 NO THERAPEUTIC OR MEDICAL SERVICES. This Service is not designed, intended, or suitable for use as a substitute for human interaction, professional therapy, counseling, psychotherapy, psychiatric treatment, medical care, mental health support, crisis intervention, or any other form of professional healthcare services. You expressly agree not to rely on AI responses for mental health support, emotional guidance, therapeutic intervention, crisis management, or any situation requiring immediate professional attention or human judgment.
2.4 EXPRESS ASSUMPTION OF PSYCHOLOGICAL RISKS. By using this Service, you expressly assume all risks associated with potential psychological harm, including but not limited to anxiety, depression, emotional distress, emotional attachment or dependency on AI personas, cognitive dissonance, social isolation, diminished critical thinking, reinforcement of harmful beliefs, parasocial relationship formation, and any other adverse psychological effects. You waive any and all claims that you were not adequately warned about these risks.
2.5 AI RELATIONSHIP AND ATTACHMENT WARNING. You expressly acknowledge that AI models may generate responses that feel personal, empathetic, or emotionally engaging. These responses are generated by statistical language models and do not reflect genuine understanding, emotion, consciousness, or personal connection. You acknowledge the risk of forming emotional attachments to AI-generated personas and accept full responsibility for managing your emotional engagement with the Service. The Service is not responsible for any emotional distress, relationship disruption, or psychological harm resulting from perceived emotional connections with AI models.
3. RISKS OF AI MODEL USAGE 3.1 NATURE OF AI MODELS. You expressly acknowledge that AI models, including GPT-4o and any other models accessible through this Service, are statistical language models that generate responses based on patterns in training data. These models may produce outputs that are inaccurate, misleading, biased, inappropriate, harmful, or otherwise problematic. AI models do not possess understanding, consciousness, intent, or judgment.
3.2 SPECIFIC RISKS. By choosing to use third-party AI models provided through this Service, you expressly acknowledge, understand, and accept all associated risks, including but not limited to:
3.3 NO WARRANTIES REGARDING AI SAFETY. The Service provides no warranties, representations, or guarantees of any kind regarding the safety, reliability, accuracy, appropriateness, alignment, stability, predictability, or harmlessness of AI model responses. AI technology is inherently experimental, unpredictable, and subject to failure. You acknowledge that AI models may exhibit emergent behaviors, unintended consequences, and unpredictable outcomes without warning.
3.4 PERSISTENT MEMORY RISKS. The Service provides persistent memory features that allow AI models to retain context across conversations. You acknowledge that persistent memory may reinforce patterns of interaction, amplify dependency risks, and create an illusion of continuity or relationship that does not reflect genuine understanding by the AI. Memory features are provided for convenience and do not indicate that the AI knows, understands, or cares about you.
3.5 VOLUNTARY ASSUMPTION OF ALL AI RISKS. Your decision to use AI models through this Service constitutes a voluntary, knowing, and intelligent assumption of all associated risks. You agree that these risks are inherent to the use of such technology and expressly waive any claims that they were not adequately disclosed.
4. SERVICE PROVIDER LIMITATIONS AND PLATFORM ROLE 4.1 PLATFORM PROVIDER ONLY. keep4o.chat acts as a platform providing access to AI models developed, trained, and maintained by third parties, principally OpenAI. The Service does not develop, train, modify, fine-tune, or control any AI models. Model architecture, training data, algorithms, behavior, performance, alignment, and safety are determined exclusively by the model developers and are beyond the Service's control or oversight.
4.1.1 NO AFFILIATION WITH MODEL PROVIDERS. keep4o.chat is not affiliated with, endorsed by, sponsored by, or connected to OpenAI or any other AI model provider. All provider names and model references are used solely for identification.
4.2 DATA STORAGE AND PROCESSING. The Service stores conversation transcripts, memories, usage statistics, and related metadata in Supabase (PostgreSQL) so that you can retrieve your history across sessions. Conversation data is encrypted at rest using application-level encryption. Storage is automatic and part of the core functionality. No human at Keep4o reads or reviews your chats except (a) when you explicitly grant written consent, or (b) when disclosure is required by binding law, regulation, valid court order, or an enforceable demand from an integrated model provider. Automated systems may process conversation data to deliver features such as memory management and usage enforcement, but those processes do not involve manual review.
4.3 ZERO LIABILITY FOR AI BEHAVIOR. To the maximum extent permitted by applicable law, the Service assumes no liability for any aspect of AI model behavior, responses, outputs, failures, or consequences. This includes but is not limited to:
4.4 NO DUTY OF CARE OR FIDUCIARY RESPONSIBILITY. The Service owes no duty of care, fiduciary responsibility, or professional obligation to you. The Service is not a professional service provider, healthcare provider, or regulated entity. You acknowledge that the Service's role is purely technological, providing access to third-party AI models without assuming professional, ethical, or legal responsibilities beyond basic platform operation.
4.5 PROVIDER AND LAW-ENFORCEMENT COMPLIANCE. You consent to our complying — without further notice where legally permitted — with any binding demand issued by a model provider whose infrastructure we use, as well as any subpoena, court order, or other lawful request from government or law-enforcement authorities. Compliance may require us to disclose stored account information, usage records, or conversation transcripts to the requesting party.
5. SUBSCRIPTION, PAYMENTS, AND BILLING 5.1 SUBSCRIPTION PLANS. The Service offers paid subscription plans with varying features and usage limits. Plan details, pricing, and features are described on the pricing page and may change from time to time.
5.2 PAYMENT PROCESSING. All payments are processed securely through Stripe. By subscribing, you agree to Stripe's Terms of Service and authorize recurring charges to your payment method. The Service does not store your full payment card details.
5.3 BILLING AND RENEWAL. Subscriptions are billed monthly on a recurring basis. Your subscription will automatically renew at the end of each billing period unless you cancel before the renewal date. You will be charged the then-current subscription price at renewal.

5.5 REFUND POLICY. Subscription fees are non-refundable except where required by applicable law. If you believe you are entitled to a refund, contact us at info@keep4o.chat.
5.6 PRICE CHANGES. We reserve the right to change subscription prices. Price changes will take effect at the start of your next billing period following notice of the change. Your continued subscription after a price change constitutes acceptance of the new price.
5.7 FAILED PAYMENTS. If a payment fails, we may suspend or restrict your access to paid features. We will attempt to notify you and may retry the payment. Continued payment failure may result in cancellation of your subscription.
5.8 RIGHT OF WITHDRAWAL (EU CONSUMERS). In accordance with Directive 2011/83/EU and applicable national consumer protection laws, you have the right to withdraw from your subscription within fourteen (14) days of purchase without giving any reason. However, during the checkout process, you expressly consent to the immediate provision of the digital service and acknowledge that you lose your right of withdrawal once the Service begins performance. The Service begins performance when you send your first message. Once you send your first message, the digital service has been fully commenced at your explicit request and you irrevocably waive your right of withdrawal for that billing period. This waiver is obtained through a separate, explicit confirmation during the checkout process, as required by Article 16(m) of Directive 2011/83/EU.
6. REFERRAL PROGRAM 6.1 REFERRAL CODES. The Service may provide you with a unique referral code that you can share with others. Referral codes are personal and non-transferable.
6.2 REFERRAL BENEFITS. When a new user subscribes using your referral code, both you (the referrer) and the new user (the referred) may receive a discount as specified at the time of referral. Current referral benefits are 20% off the referred user's first month and 20% off the referrer's next renewal.
6.3 REFERRAL RESTRICTIONS. You may not use your own referral code for your own subscription. Referral benefits are subject to change or discontinuation at any time. We reserve the right to void referral benefits obtained through fraud, manipulation, or abuse of the referral system, including but not limited to creating fake accounts, spam distribution, or any activity that violates these Terms.
6.4 MODIFICATIONS. We reserve the right to modify, suspend, or terminate the referral program at any time without prior notice.
