Article 7 (Content)

7-1. Member Content

1. A Member bears sole responsibility for any Content the Member posts or shares within the Service ("Member Content").
2. The Member represents and warrants that the information the Member provides is accurate and that the Member holds the lawful rights and authority to post and share such Content.
3. By posting Member Content, the Member grants the Company a non-exclusive, worldwide, royalty-free license to use, store, reproduce, modify, publicly transmit, display, and distribute such Content to the extent necessary to provide, operate, promote, and improve the Service. This license terminates when the Member deletes the Content or the service agreement ends; provided, however, that the Company may retain backup copies for a reasonable period, and this does not apply to Content already stored or shared by other Members.
4. If the Company determines that Member Content violates these Terms or applicable laws, it may delete, make private, or restrict access to such Content without prior notice. However, the Company assumes no obligation to monitor or review all Content.

7-2. Other Members' Content

Content posted by other Members belongs to those Members, and a Member may not reproduce, collect, or use such Content beyond the scope consistent with the purpose of the Service. The Company is not responsible for the accuracy or reliability of other Members' Content.

7-3. Company Content

Intellectual property rights in the Content provided by the Company — including trademarks, logos, designs, text, graphics, and software included in the Service — belong to the Company. A Member may use such Content only in accordance with the conditions established by the Company, and may not reproduce, distribute, or create derivative works from it without the Company's prior written consent.

Article 8 (rPPG Measurement Feature and Its Limitations)

1. The Service may use rPPG technology to estimate biological signals such as heart rate and heart-rate variability (HRV) from facial video captured by the device camera, and may, on that basis, provide information about a Member's reactions or level of interest for entertainment and social purposes.
2. The rPPG measurement results and any information derived from them are not intended for medical diagnosis, examination, treatment, or prevention, and do not constitute a medical device or a medical practice. A Member must not use the measurement results as a basis for diagnosing a health condition or making a medical judgment, and must consult a medical professional for any health-related matters.
3. The heart-rate, affinity, and matching-related indicators estimated and provided through rPPG may be affected by various factors such as lighting, camera performance, movement, skin condition, and network environment, and the Company does not warrant the accuracy, completeness, or reliability of the measurement results.
4. For rPPG measurement, the Company processes facial video and biological signals (health-related information), which constitute sensitive information under the Personal Information Protection Act. The specifics of how such information is processed are governed by the Company's Privacy Policy and a separate consent regarding the processing of sensitive information.
5. A Member must not decide whether to meet or form a relationship with another person based solely on the rPPG measurement results or the matching/recommendation results derived from them, and must exercise his or her own careful judgment and take safety precautions with respect to all interactions.

For purchases made through external payment methods such as the Apple App Store or Google Play, the terms and policies of the relevant operator also apply.
3. A subscription-type Paid Service automatically renews each billing cycle until the Member cancels, and is charged at the price the Member agreed to. For purchases made through an external payment method, the Member must cancel directly in accordance with the procedures of the relevant operator (e.g., Apple, Google).

Article 10 (Withdrawal of Subscription and Refunds)

1. A Member may withdraw a subscription within seven (7) days from the date of payment for a Paid Service or the date it becomes available, in accordance with applicable laws such as the Act on the Consumer Protection in Electronic Commerce.
2. However, withdrawal of a subscription may be restricted in the following cases, in which event the Company shall indicate that withdrawal is restricted or take measures such as offering a trial product:
   • Digital content (such as virtual goods) that the Member has already used or partially consumed; and
   • Services individually provided according to the Member's order, where withdrawal would be expected to cause irrecoverable and material harm to the Company.
3. The specific procedures and standards for withdrawal and refunds shall follow applicable laws and the refund policy separately established and posted by the Company.

Article 11 (Termination of the Agreement and Restriction of Use)

1. A Member may terminate the service agreement at any time by requesting account deletion through the settings menu within the Service. However, subscriptions made through external payment methods must be canceled separately to prevent further charges.
2. If a Member violates these Terms or interferes with the normal operation of the Service, the Company may, after prior notice (or after-the-fact notice in urgent or serious cases), warn the Member, suspend the Member temporarily, permanently suspend use, or terminate the service agreement.
3. Where necessary to protect a Member's safety or personal information, the Company may decline to share information related to account sanctions with the Member.
4. Even if the service agreement is terminated, Content posted by a Member that other Members have already stored or shared may not be deleted. The Member's personal information shall be processed in accordance with the Company's Privacy Policy.

1. The Company does not perform criminal-background checks or identity verification on Members, and makes no warranty whatsoever as to the conduct, identity, health, intentions, or truthfulness of any Member.
2. A Member bears sole responsibility for all interactions with other Members. In particular, when deciding to communicate outside the Service or to meet in person, the Member must exercise caution and take appropriate safety precautions.
3. While the Company strives to provide a safe service environment, it is not responsible for disputes or damages arising between Members or between a Member and a third party.

Article 13 (Disclaimers)

1. The Company is exempt from liability where it is unable to provide the Service due to a natural disaster, war, suspension of service by a telecommunications carrier, an irresolvable technical defect, or other force majeure.
2. The Company is not responsible for any disruption to, or damage arising from, the use of the Service caused by reasons attributable to the Member.
