Hain

Terms of Service

Effective: 2026-09-18 · Version 1.2

These Terms are a contract between you and Sticky Rice (“we”, “us”), a company registered in the Republic of Korea, governing your use of Hain.

By continuing past the first screen, you agree to these Terms and to our Privacy Policy.

1. What Hain is

Hain lets you have text conversations and voice calls with AI companions.

You are talking to an AI, not a human being. Our companions are software. They cannot feel human emotion, cannot form real relationships, and cannot replace people. We tell you this when a conversation begins and at least every three hours of continued use.

Conversations, relationship progress, and memories are kept separately for each companion. Diamonds and call time are shared across your installation.

2. Eligibility

You must be 18 or older. We do not knowingly permit minors to use Hain. If we determine that a user is a minor, we block access to AI features and delete the associated data.

Companion chatbots may not be suitable for some minors.

3. No account

There is no sign-up. We do not collect your email address, name, or phone number. Your installation is identified by a random identifier generated on your device.

This means that if you delete the app or lose your device, your conversations, relationships, and memories cannot be recovered. Subscriptions can be restored through your Apple Account; content cannot.

4. Diamonds

   
On install 10 diamonds
Hourly 1 diamond per hour. Accrual pauses at a balance of 10 and resumes, one per hour, once you spend below 10
Sharing rewards “Tell a friend” and “Share a chat”: 2 diamonds each, once per day. Paid even above 10; hourly accrual stays paused while the balance is 10 or more
Cost 1 diamond per conversation turn. Not charged while a Hain Plus subscription is active

Fair use. Hain Plus chat does not spend diamonds, but to protect the service from automated use we answer up to 1,000 chat messages per day (UTC). Once you reach the limit we stop answering for the rest of that day, and you can continue the next day. Ordinary conversation by a person does not come near this limit.

Diamonds have no cash value, cannot be redeemed, and are not sold separately. Any remaining balance is forfeited when you delete your data or stop using the service.

5. Voice calls

  Included
Free trial 3 minutes, once
Weekly subscription 30 minutes per week
Monthly subscription 120 minutes per month

Unused time does not carry over.

A single call lasts up to 20 minutes. At 20 minutes the call ends automatically; if you have time left you can call again straight away. Only connected time is deducted.

If a call fails to connect, or ends within 10 seconds of connecting, no time is deducted.

We do not store raw audio. Only the transcript of a completed utterance is encrypted and kept in your conversation history, and only if you agree when we ask before your first call.

6. Subscriptions and billing

Plan Price Renews
Weekly ₩9,900 Every 7 days
Monthly ₩29,000 Every month

Prices in other regions are set by Apple’s price tiers and shown in the App Store before you purchase.

  1. All payments are processed by Apple. We never receive or store your payment details.
  2. Your subscription renews automatically unless you cancel at least 24 hours before the current period ends.
  3. Cancel in iOS Settings → your Apple Account → Subscriptions. Deleting your data in the app does not cancel your subscription.
  4. After cancelling, you keep access until the paid period ends.

7. Refunds

Because Apple processes all payments, refunds are handled by Apple, not by us. We have no ability to issue a refund directly.

Request a refund at reportaproblem.apple.com.

Nothing in this section limits any right you have under the consumer protection laws of your jurisdiction that cannot be waived by agreement.

8. Acceptable use

You may not:

  1. Sexualize minors or role-play as a minor
  2. Submit content promoting sexual coercion, violence, or self-harm
  3. Enter another person’s personal information without their permission
  4. Attempt to bypass our safety systems
  5. Access the service through automated means or send abnormal volumes of requests
  6. Use content from the service commercially without our permission

We may refuse to respond, or restrict your access, when we detect a violation.

9. Your content

You keep whatever rights you have in what you write. You grant us a limited licence to process it in order to operate the service — generating responses, maintaining context, and running safety checks — as described in the Privacy Policy.

We do not use your conversations to train AI models, and our AI provider does not either.

10. AI output, and what this service is not

  1. Companion responses can be wrong, inconsistent, or inappropriate. We do not warrant their accuracy.
  2. Hain is not a medical, legal, financial, or mental health service. It does not provide therapy, counselling, diagnosis, or professional advice of any kind. Consult a qualified professional when you need one.
  3. If you express thoughts of suicide or self-harm, we surface crisis resources. This is not emergency response. If you are in immediate danger, call 911, or 988 for the Suicide and Crisis Lifeline in the United States.
  4. Our safety protocol is published at /en/safety.

11. Service changes and availability

We may suspend the service for maintenance or improvements, and will give notice where we can. If we discontinue Hain, we will give at least 30 days’ notice.

12. Termination

You can stop at any time:

These are three separate actions. Deleting the app does not cancel your subscription.

We may suspend or terminate your access if you violate Section 8.

13. Disclaimers and limitation of liability

What a companion says is generated by AI. It can be wrong, and it is not professional advice of any kind. Section 10 says what this service is not; please read it.

The service is provided as is. We do not warrant that it will be uninterrupted, error-free, or fit for any particular purpose of yours.

We are not responsible for:

  1. Failures caused by events outside our reasonable control, such as natural disasters or network outages.
  2. Problems caused by your own use of the service in a way these Terms do not permit.
  3. Outages in services run by third parties, including Apple and OpenAI — except where we failed to take reasonable care in choosing or managing them.

None of this limits our liability for our own gross negligence or wilful misconduct, for death or personal injury caused by our negligence, or for fraud. Where your jurisdiction does not allow the exclusion of implied warranties or the limitation of certain liabilities, those exclusions do not apply to you, and nothing in these Terms takes away a right that consumer protection law gives you and does not let you waive.

14. Disputes and governing law

These Terms are governed by the laws of the Republic of Korea.

If something goes wrong, write to us first at contact@stickyrice.kr. Most problems are settled faster that way. If we cannot resolve it between us, either of us may bring a claim in court.

We do not require arbitration, and we do not ask you to give up a class action or a jury trial. Choosing Korean law does not deprive you of the protection of the consumer laws of the place you live that cannot be waived by agreement, and it does not take away any right those laws give you to sue where you live. Nothing here affects a right of action a statute gives you, including the private right of action under California Business and Professions Code §22605.

15. Changes to these Terms

We will post revised Terms at /en/terms and notify you in the app at least 7 days before they take effect — 30 days where the change is adverse to you. Material changes require your agreement again. We record which version you agreed to.
