Youth Protection Policy

(Effective: July 27, 2026)

nonscale.co.ltd (hereinafter the "Company") establishes and implements this Youth Protection Policy in accordance with the Youth Protection Act, the Act on Promotion of Information and Communications Network Utilization and Information Protection, the Act on the Protection of Children and Youth against Sex Offenses, and other applicable standards, including app market policies, so that youth may be protected from harmful information and use the Service safely, as set forth below.

This Policy addresses the restriction of access to information harmful to youth in general, the handling of reports, the designation of a Youth Protection Officer, and counseling channels. Specific zero-tolerance standards and law enforcement reporting procedures regarding Child Sexual Abuse and Exploitation (CSAE) and Child Sexual Abuse Material (CSAM) are also separately published in the "Child Safety Standards (CSAE)."

The Company describes in this Policy only those measures that are actually in operation in the Service at present. Features that have not yet been implemented will be reflected by amending this Policy once their implementation is confirmed.

Article 1 (Purpose)

The purpose of this Policy is to set forth the Company's activities and responsibilities for protecting youth from harmful information and fostering a sound environment for use of the location-based social network service "Where U At" or "WUA" (including the mobile application and any web services incidental thereto; hereinafter the "Service") operated by the Company.

In this Policy, "youth" means a person under 19 years of age pursuant to Article 2(1) of the Youth Protection Act, provided that a person who has reached January 1 of the year in which they turn 19 years of age is excluded. This is a concept distinct from the minimum age for membership eligibility (14 years of age or older).

In this Policy, "KOONG" means a post that a user captures with the camera at the user's current location and leaves on the map, and "comment" means text or photos appended to a KOONG.

Article 2 (Relationship with the CSAE Policy)

1. The Youth Protection Policy is a document centered on domestic law that addresses information harmful to youth in general, age restrictions, reporting and blocking, the Youth Protection Officer, and counseling channels.

2. The Child Safety Standards (CSAE) is a document specialized in sexual safety harms - such as sexual abuse and exploitation of children and youth, CSAM, grooming, and sextortion - prepared for Google Play submission and global child safety response.

3. The two documents may overlap in part. This is because child and youth sexual exploitation material constitutes both information harmful to youth and a matter requiring separate emergency response, and accordingly this Policy and the CSAE Policy are applied together to matters involving sexual exploitation or CSAM.

Article 3 (Age Rating and Membership Restrictions)

1. The Service's app market age rating is displayed in accordance with the review standards of each country and store. The Company complies with the age rating of 12 and above applicable to the Korean store, as well as the app market ratings applicable in each country, and operates the Service's membership eligibility at 14 years of age or older.

2. The Company restricts membership registration by persons under 14 years of age. Age verification is based on the four-digit birth year that the user directly enters at the time of registration, and the server also checks whether the user is under 14 years of age. However, because this procedure is based on the user's self-declaration, it does not include real-name verification or legal guardian confirmation procedures, and it cannot technically filter out a falsely entered birth year. The Company may restrict the use of an account for which false age information is confirmed, pursuant to Article 6 of this Policy.

3. If it is confirmed that the personal information of a child under 14 years of age has been collected, the Company will, without delay, destroy such information and restrict the account, pursuant to Article 22-2 of the Personal Information Protection Act ("PIPA"). A legal guardian may request access to, correction of, deletion of, or suspension of processing of the child's personal information by email (admin@thenonscale.com), in accordance with the Privacy Policy.

4. For users who fall under the definition of "youth" (under 19 years of age) under the Youth Protection Act, the access restrictions on harmful information and the protective measures set forth in this Policy apply.

Article 4 (Scope of Information Harmful to Youth)

The Company manages the Service so that the following information is not distributed on the Service.

• Information determined to be media harmful to youth and publicly notified by the Minister of Gender Equality and Family pursuant to the Youth Protection Act and related statutes, or information subject to labeling and packaging requirements under the same Act

• Information relating to obscene materials, illegally filmed materials, fabricated sexual images or videos, child and youth sexual exploitation material, prostitution and sexual solicitation, grooming, and sextortion

• Information that may impair the sound use of the Service by youth, such as excessive violence, encouragement of self-harm or suicide, narcotics and illegal drugs, gambling, weapons, and guidance on methods of committing crimes

• Information that exposes or seeks to obtain a youth's personal information, contact information, precise living area, school, home, real-time location, or other private matters

• Information that promotes hatred, harassment, bullying, threats, exploitation, or other harm directed at youth

Article 5 (Restriction of Access to Harmful Information and Management Measures)

1. The Service is not operated for the purpose of providing media harmful to youth or adult content. If a user posts or shares harmful information, the Company may delete it, block its transmission, restrict its exposure, or place it in a pending review status.

2. If the Company identifies information requiring the labeling of media harmful to youth or restriction of access thereto under Article 42 of the Network Act, the Company will, in principle, delete or block such information, and where the Company becomes aware of a post made public in violation of the labeling obligation, the Company will delete it without delay pursuant to Article 44-2(3) of the same Act, even in the absence of a report.

3. The technical and administrative measures currently operated by the Company, and their limitations, are as follows. The Company does not warrant that these measures filter out all harmful information in advance, and it uses user reports and operator review together with these measures.

• Automated image safety verification: Only for KOONG photos and the first frame of KOONG videos, an external image analysis service automatically determines whether the content is obscene or violent. This automated verification does not apply to photos attached to comments or chats, or to profile photos.

• Text filtering: Only for chat messages, the Company screens for abusive or hateful language and for patterns exposing personal information such as resident registration numbers, phone numbers, and addresses.

• Priority classification of the report queue and operator review: Reports made on grounds of child and youth safety, self-harm or suicide, or threats are classified with the highest priority.

• Hash database matching for child sexual exploitation material has not currently been implemented. Such content is addressed through user reports and operator review.

4. A user whose upload has been blocked solely by the automated determination described in paragraph 3 may request human re-review by email (admin@thenonscale.com). The Company will review such requests in the order received and respond with the result.

5. Where serious illegal information, such as child and youth sexual exploitation material or illegally filmed material, is discovered or reasonably suspected, the Company will immediately block public access to and transmission of such information pursuant to Article 22-5 of the Telecommunications Business Act, preserve evidence to the extent necessary for legal reporting and cooperation with investigations, and report the matter to the relevant authorities. This measure applies equally not only to public posts but also to group chats and one-on-one conversations.

Article 6 (Reporting, Blocking, and Sanctions)

1. Users may report content or other users from the screens for major user content, including KOONG, comments, profiles, groups, and chat messages, and may block malicious users. Blocking is a measure that prevents the blocked user's content from appearing on the screen of the user who initiated the block.

2. The reasons available for selection when reporting in the app are: spam, inappropriate content, harassment, false information, exposure of personal information, child and youth safety, self-harm or suicide, threats, and other. Reports made on grounds of child and youth safety, self-harm or suicide, or threats are classified into the highest-priority queue for urgent review. To prevent abuse of the reporting function, reports against the same target must be spaced at least five minutes apart, and a single user is limited to submitting five reports within a 24-hour period.

3. With respect to clearly harmful information or malicious users, the Company will, without delay, take necessary measures such as deletion, restriction of exposure, account suspension, permanent blocking, or reporting to the relevant authorities. Where urgent harm or suspected illegality is present, the Company may take action first, without prior notice.

4. A user who objects to a sanction may file an appeal by email (business@thenonscale.com). There is currently no separate in-app screen for submitting appeals, and email is the sole channel available. The Company will inform the user of the review result to the extent that doing so does not compromise the safety and personal information of the reporting party and the victim.

Article 7 (Activities for the Protection of Youth)

1. The Company establishes plans to protect youth from harmful information and monitors the risk of exposure to harmful information in the course of operating the Service.

2. The Company provides training and internal guidelines for operations personnel on youth protection, blocking of harmful information, CSAE/CSAM response, and protection of personal information and location information.

3. Because the Service is a location-based service, particular care is required regarding the exposure of a youth user's location. When publishing a KOONG, the location displayed on the map may be adjusted by the user within a maximum radius of 100 meters from the point of capture, and each user may set the visibility of each KOONG. However, this adjustment is merely a function for shifting the point displayed on the map and is not a means of concealing the place of capture; the location of a published KOONG is exposed to other users in accordance with its visibility setting. In addition, no function is currently applied to separately restrict the default visibility setting for the accounts of minor users, and accordingly youth users and their guardians are encouraged to check the visibility setting themselves so that living areas such as home and school are not repeatedly revealed.

4. Where a youth or a guardian requests a report or counseling, the Company will promptly accept the request and, where necessary, concurrently provide guidance to external specialized institutions or investigative authorities.

Article 8 (Designation of the Youth Protection Officer)

Regardless of whether a statutory designation obligation applies, the Company designates a Youth Protection Officer and staff responsible for youth protection matters, as follows. The Company does not currently operate a separate main phone line, and all inquiries and reports are received at the email address below.

Article 9 (Victim Counseling and Grievance Handling)

Youth and their guardians may request counseling and grievance handling at the contact information above regarding harm arising in the course of using the Service, such as harmful information, sexual exploitation, harassment, or exposure of personal information or location information, and the Company will promptly proceed with measures to prevent the spread of harm and take other necessary action. Where there is urgent danger or suspected criminal victimization, immediate assistance may be sought from investigative authorities or external specialized institutions.
