Terms of Service

Effective: August 29, 2026

These Terms of Service ("Terms") are an agreement between you and Kai Research Inc. ("Kai," "we," "us," or "our") governing Kai's websites, apps, AI features, and related services (collectively, the "Services").

By using Kai, you agree to these Terms and to follow our Community Rules. Our Privacy Policy explains how we handle your information, and our Teen Safety page describes protections for teen accounts.

1. Eligibility and accounts

You must be at least 13 years old to use Kai. Kai does not currently provide a parental-consent or guardian-authorization flow. If the law where you live requires a parent or legal guardian to authorize your use of Kai or our processing of your information, you may not use Kai until Kai offers an appropriate process. Some Kai features have additional age or health-safety requirements. You must be an adult to create or manage a paid-membership offering or payout account.

You agree to provide accurate account information, keep access to your account and signed-in devices secure, and promptly notify us at [email protected] if you believe your account has been compromised. You are responsible for activity on your account unless applicable law says otherwise. Kai currently supports third-party sign-in providers and does not issue a separate Kai password.

2. Acceptable use

You may use the Services only for lawful personal purposes or for creator and Group activities Kai expressly makes available, and in accordance with these Terms and our Community Rules. You may not:

  • harm, threaten, exploit, harass, stalk, or deceive another person;
  • promote dangerous health behavior, self-harm, eating disorders, illegal products, or other conduct prohibited by our Community Rules;
  • infringe intellectual-property, privacy, publicity, or other rights;
  • impersonate another person or misrepresent qualifications, results, or affiliations;
  • send spam, scams, malware, phishing links, or interfere with the Services or another account;
  • scrape or access the Services through unauthorized automated means;
  • probe, bypass, reverse engineer, or defeat security or access controls, except where applicable law expressly permits it; or
  • use Kai or its outputs to develop a competing model or service except with our written permission.

3. Your content

You retain ownership of posts, photos, messages, AI inputs, and other content you submit to Kai ("User Content"). You are responsible for your User Content and must have the rights and permissions needed to share it.

To operate the Services, you grant Kai a worldwide, non-exclusive, royalty-free, sublicensable license to host, store, reproduce, format, adapt for technical delivery, transmit, display, and distribute your User Content. This license is limited to operating, protecting, and improving the Services according to your settings. For example, we need it to display a post to the audience you choose, create thumbnails, route an AI prompt to a model provider, or keep authorized backups.

The license ends when your User Content is deleted, except to the extent content was shared with others and they retained it, or copies must remain temporarily in backups, safety records, or legally required records. Feedback and product suggestions may be used without restriction or compensation, but we will not publicly identify you as their source without permission.

4. AI features

Kai uses artificial intelligence to provide coaching, summaries, plans, suggestions, and conversational responses. Your prompts, uploaded context, connected data, and instructions are "Inputs"; generated responses are "Outputs."

As between you and Kai, you retain your rights in Inputs and, to the extent permitted by law, own Outputs generated for you. You grant the license in Section 3 as needed to process Inputs and deliver Outputs. Outputs may not be unique, and other users may receive similar content.

AI can be inaccurate, incomplete, outdated, or inappropriate. You must review Outputs and use independent judgment before relying on them. Do not use an Output as a diagnosis, treatment decision, emergency instruction, or substitute for a qualified professional. Do not submit information you lack the right to share. Our Privacy Policy explains how AI providers process Inputs and Outputs.

Memory is optional. When available, its same-product, cross-product, and sensitive-memory settings are separate controls. You can inspect, suppress, or erase remembered facts and disable Memory in Data Controls.

5. Health and fitness notice

Kai provides general informational, fitness, nutrition, and wellness support. Kai is not a healthcare provider, emergency service, or substitute for professional medical advice, diagnosis, or treatment. Kai does not create a clinician-patient relationship.

Consult a qualified healthcare professional before starting or changing a diet, exercise, sleep, recovery, or wellness program, particularly if you have a medical condition, take medication, are pregnant or nursing, have a history of disordered eating, or experience pain or concerning symptoms. Stop an activity and seek appropriate help if you feel unwell. Call emergency services in an emergency.

Individual outcomes vary. Kai does not promise any particular health, fitness, weight, performance, or wellness result.

6. Subscriptions, paid memberships, and payments

Some Kai features require a paid Kai subscription. Kai may also let a user or Group offer a recurring paid membership for access to that creator's subscriber-only Posts. A paid membership does not change the subscriber's Kai account tier, product entitlements, or AI usage allowance.

Before purchase, the applicable checkout shows the offering, price, billing period, included access, and any trial or introductory terms. Unless the offer says otherwise, subscriptions and paid memberships renew automatically for the same billing period at the then-current disclosed price until canceled.

Purchases may be billed by Apple, Google Play, Stripe, or another identified payment provider. You authorize the provider to charge the payment method on file, including applicable taxes. Provider terms may also apply.

You can cancel through the provider that bills you. Cancellation normally stops renewal and takes effect at the end of the paid period; access generally continues until then. Deleting your Kai account does not automatically cancel a subscription billed by Apple, Google Play, or another external provider. Cancel that subscription in the provider's subscription settings before deleting your account if you do not want it to renew.

Except where required by law or stated in a specific offer, fees are non-refundable and we do not provide credits for partial periods. For a store-billed purchase, request any refund through that store. Kai may change future prices with the notice required by law and the billing provider.

Paid-membership creators

Only an adult whose age assurance resolves to adult may create or manage a paid-membership offering. A user controls their own offering. An active Group administrator may manage a Group offering, while the first administrator who starts payout setup becomes the designated owner of that Group's Stripe payout account.

Kai is the Stripe merchant for paid memberships. Kai currently charges a zero-percent platform fee, but zero percent does not mean there are no deductions. Stripe processing fees, applicable taxes, refunds, disputes, and transfer reversals reduce the amount available to the creator. Kai transfers the remaining amount after those deductions and may delay, withhold, or reverse funds when required to process a refund or dispute, correct an error, prevent fraud, or comply with law. Stripe onboarding and payout terms also apply.

Creators are responsible for describing an offering accurately, providing the promised content while the membership is active, holding the rights needed for that content, and complying with applicable advertising, consumer-protection, tax, and other laws. Kai may suspend an offering, checkout, transfer, or payout account to enforce these Terms, address risk, or comply with provider requirements or law.

7. Kai materials and intellectual property

The Services—including Kai software, designs, trademarks, documentation, and content we provide—belong to Kai or our licensors and are protected by law. Subject to these Terms, Kai grants you a limited, personal, non-exclusive, non-transferable, revocable right to use the Services. No other rights are granted.

Do not post content you do not have the right to share. To report copyright or other intellectual-property infringement, email [email protected] with the subject "Intellectual Property Report" and include:

  • your contact information and signature;
  • identification of the protected work or right;
  • the Kai content and location you want reviewed;
  • a good-faith statement that the use is not authorized; and
  • a statement that your report is accurate and, for a copyright report, made under penalty of perjury that you are authorized to act for the rights holder.

We may remove content and terminate repeat infringers where appropriate. Knowingly submitting a false report may create liability.

8. Enforcement, suspension, and termination

We may investigate suspected violations and may remove content, suspend an account, or terminate access. Severe violations may result in immediate action. We may also act to protect users, comply with law, address security or operational risk, or discontinue a Service.

Where appropriate, we will provide notice and an opportunity to appeal by contacting [email protected]. You may stop using Kai at any time, deactivate your account without deleting its content, or request deletion through supported settings or the process described on our Account Deletion page. Member-requested deactivation makes product access unavailable until explicit provider-verified reactivation. Member-requested deletion is a separate permanent flow that makes the account unavailable immediately, revokes current sessions, starts deletion work, and cannot be cancelled.

Terms that by their nature should survive termination—including ownership, licenses already exercised, disclaimers, liability limits, and dispute terms—will survive.

9. Third-party services

Kai may link to or interoperate with third-party sign-in, health-platform, wearable, payment, communications, or other services. Those services are governed by their own terms and policies. Kai is not responsible for third-party services outside our control.

10. Disclaimers

To the maximum extent permitted by law, the Services are provided "as is" and "as available." Kai and its licensors disclaim all warranties, express or implied, including merchantability, fitness for a particular purpose, non-infringement, accuracy, and uninterrupted or error-free operation. We do not warrant that content, AI Outputs, or health and fitness guidance will be safe or suitable for every person.

Some jurisdictions do not allow certain disclaimers, so some of this section may not apply to you.

11. Limitation of liability

To the maximum extent permitted by law, Kai and its officers, directors, employees, affiliates, and agents will not be liable for indirect, incidental, special, exemplary, punitive, or consequential damages, or for lost profits, data, goodwill, or opportunities, arising from the Services—even if advised those damages were possible.

To the maximum extent permitted by law, Kai's total liability for all claims relating to the Services will not exceed the greater of (a) the amount you paid Kai for the Services during the 12 months before the event giving rise to the claim or (b) US $100.

These limits do not exclude liability that cannot lawfully be limited, including rights available under mandatory consumer law.

12. Indemnity

To the extent permitted by law, you will defend, indemnify, and hold Kai and its affiliates, officers, directors, employees, and agents harmless from third-party claims arising from your User Content, your unlawful misuse of the Services, or your material breach of these Terms. This obligation does not apply to the extent a claim results from Kai's own conduct.

13. Disputes and governing law

Before filing a formal claim, you and Kai agree to try in good faith to resolve the dispute by written notice to [email protected]. The notice should describe the issue and requested resolution. Either party may proceed if the dispute is not resolved within 30 days.

These Terms are governed by Delaware law, without regard to conflict-of-law rules. Except where mandatory consumer law permits another forum, claims must be brought in the state or federal courts located in Delaware, and each party consents to their jurisdiction. Nothing in these Terms prevents either party from seeking eligible relief in small-claims court or urgent injunctive relief.

14. Changes and general terms

We may update the Services or these Terms. If a change is material, we will provide reasonable advance notice through the Services, by email, or by another appropriate method. The updated Terms will identify their effective date. Continuing to use Kai after the effective date means you accept the updated Terms.

If a provision is unenforceable, the remaining provisions remain effective. Our failure to enforce a provision is not a waiver. You may not assign these Terms without our consent; Kai may assign them in connection with a reorganization, financing, merger, sale, or transfer of the Services. These Terms and the policies they incorporate are the entire agreement between you and Kai about the Services.
