Ruen Terms of Service

This English version is a translation for convenience. If it differs from the Korean version, the Korean version prevails.

Article 1 (Purpose)

These terms set out the conditions and procedures for using the Ruen service (the "Service") provided by Hairgraphy (the "Operator").

Article 2 (Posting and changes)

  1. The Operator posts these terms in the app and emails a copy on request.
  2. The Operator may change these terms to the extent permitted by law.
  3. When the terms change, the Operator announces the changes and the effective date in the app, and shows the changes separately and asks for consent the first time you open the app after the effective date.
  4. If you do not agree to the changed terms, you cannot use the Service and may stop using it.

Article 3 (Eligibility and service region)

  1. The Service is available only to residents of the Republic of Korea aged 19 or older.
  2. The Service is provided only in the regions the Operator designates. You are responsible for any consequences of using it outside those regions or misstating your age or country of residence, and the Operator may stop your use as soon as this is confirmed.

Article 4 (AI service)

  1. The Service runs on generative AI, and the characters' replies are generated by AI.
  2. AI replies may be untrue or inaccurate, and the Operator does not guarantee their accuracy.
  3. The Service is not professional advice (medical, psychological counselling, legal, financial or otherwise). You decide your own judgements and actions based on the replies.
  4. The Service lets you talk with a fictional AI character. It does not connect you with real people and has no user-to-user chat.
  5. Because the Service includes relationship conversation with the character, it is for adults only, and the app checks that you are an adult when it first starts.
  6. In every relationship setting, the character is set not to engage in sexual or adult content, and when signs of crisis are detected, the app shows where you can get help.

Article 5 (Ruen AI and external AI services)

  1. Ruen AI generates replies with an external AI model, through the Operator's server and OpenRouter. Included usage and usage limits of paid plans are shown on the pricing page.
  2. If you connect your own AI account, that provider's terms and separate charges may apply. If you connect your own ChatGPT account, OpenAI's terms and your account's data settings (including whether data is used for training) apply, and the Operator is not responsible for actions OpenAI takes, such as restricting your account.
  3. The Operator is not liable for damage caused by reasons beyond its control, such as outages, policy changes or account restrictions of external AI services.

Article 6 (Changes to and suspension of the Service)

  1. The Service is free during the closed beta. When paid sales start, the paid features shown on the pricing page are provided as well.
  2. The Operator may change or suspend all or part of the Service, or end the Service, for the following reasons:
    1. closing the business or deciding to end the Service (paid users are notified in advance and refunded for the remaining period);
    2. suspension or policy changes of connected services such as external AI providers;
    3. responding to security vulnerabilities or safety issues;
    4. requirements of law or the authorities;
    5. equipment failure.
  3. In the cases of item 2, the Operator announces it in the app in advance. If advance notice is not possible for reasons 2 to 5, it is announced afterwards.

Article 7 (Your obligations)

You must not:

  1. violate the law or these terms;
  2. infringe the rights of others;
  3. request sexual content that suggests minors;
  4. request sexual conversation or the generation of sexual voice or images;
  5. bypass the Service's safety measures, or reverse-engineer or modify the Service;
  6. use the Service in bulk by automated means.

Article 8 (Restrictions)

If you violate Article 3 or 7, the Operator may restrict your use of the Service or terminate the contract. In urgent cases, it may restrict first and notify you afterwards.

Article 9 (Data storage)

  1. Your data, such as conversation history, is stored on your device. Account and usage information needed for Ruen AI is processed on the Operator's server (see the Privacy Policy).
  2. The Operator is not liable for data loss for which it is not responsible, such as a broken or lost device or your own deletion.

Article 10 (Limitation of liability)

The Operator does not compensate damage you suffer without the Operator's fault.

Article 11 (Rights)

  1. Rights in the Service, the characters, 3D models, voices and software belong to the Operator or the rightful holders.
  2. You may use the Service only for personal, non-commercial purposes, and may not extract, copy or redistribute the characters, models or voices.

Article 12 (Ending the contract)

  1. You can stop using the Service at any time with the app's data deletion function or by uninstalling the app.
  2. Cancel a subscription through customer support (email [email protected] · phone +82-10-9203-0278). Uninstalling the app or deleting data on your device alone does not cancel a paid subscription.
  3. Withdrawing a required consent ends the service contract. Renewal stops only if you also cancel the subscription as described in item 2.
  4. The Operator may end the contract when the Service ends or for the reasons in Article 8.

Article 13 (Governing law and jurisdiction)

  1. These terms are governed by the laws of the Republic of Korea. Where mandatory consumer protection rules apply in your region of residence, those rules prevail.
  2. Lawsuits about the Service are brought before the court with jurisdiction under the Civil Procedure Act.

Article 14 (Paid services and payment)

  1. The Operator shows the content, price, included Ruen AI usage, usage limits and term of paid services on the pricing page and the payment screen.
  2. Subscriptions are charged automatically each billing period until you cancel, and you can cancel at any time through customer support (email [email protected] · phone +82-10-9203-0278). After you cancel, you are not charged from the next billing date and you keep access until the end of the period you paid for.
  3. If the Operator gives a free pass (for example a closed beta reward), the Operator notifies the user in the app starting 30 days before the pass ends, and automatic billing starts only if the user agrees in the app to switch to a paid plan. If the user does not agree, only the free period ends. For users who already have a paid subscription, the deferred billing resumes under the existing contract.
  4. For consumers in Korea, a price increase on a subscription or a switch from free use to a paid subscription applies only with prior consent, obtained within the legal period, to the date, the old and new price and the payment method. The Operator also explains the cancellation terms, method and effect, and never charges a changed amount to users who did not agree.
  5. The seller is Hairgraphy, as shown on the payment screen and the order confirmation.

Article 15 (Withdrawal and refunds)

Withdrawal and refunds follow the Refund Policy and the applicable laws.

Addendum

These terms take effect on 2026-10-08.
