Youth Protection Policy

(Effective: October 11, 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, the desktop application installed on a computer (macOS or Windows), 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"). However, material subject to child safety-related preservation under Article 3 of the Privacy Policy (reports and moderation records) and Section 3 of the Child Safety Standards (CSAE), and the information of any account whose destruction is deferred as a result, will be destroyed after that preservation ends. 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: For KOONG photos, certain scenes of KOONG videos (the first scene and portions from the middle and the end), photos and GIFs attached to comments or chats (including group chats and one-on-one conversations), and group photos, an external image analysis service automatically determines whether the content is obscene or violent. Uploads that meet the blocking criteria are blocked, and a KOONG that is determined to be at a borderline level, or for which the screening could not be completed, is withheld so that it is visible only to its author until reviewed by an operator. This automated verification does not apply to other scenes or the audio of videos.

• Text filtering: Only for chat messages (including one-on-one conversations), the Company restricts the sending of messages that contain abusive language, patterns exposing personal information such as resident registration numbers, phone numbers, email addresses, and detailed addresses (lot numbers and building/unit numbers), or an excessive number of links, and displays "Under review" on messages that contain hateful expressions, links suspected of fraud, or excessively repeated characters. Automated text screening does not apply to other text, such as the body text of KOONG, comments, hello-wall greetings, and words posted in Plaza.

• Limit on starting conversations: To reduce spam and unwanted contact, every user may start no more than 15 new one-on-one conversations per day with users who do not trace them.

• Priority classification of the report queue and operator review: Reports made on the grounds of "Child safety / minor abuse", "Self-harm or suicide risk", or "Violence 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 or chat message has been blocked, or whose KOONG has been withheld from publication, solely by the automated determination described in paragraph 3 may request an explanation of that determination or human re-review by email (admin@thenonscale.com). The Company will review such requests in the order received and respond with the result. A KOONG photo whose upload has been blocked is retained for 14 days after being blocked for the purpose of re-review and is then destroyed; accordingly, once this period has elapsed, a re-review based on the original may be difficult.

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 and report the matter to the relevant authorities, and may preserve evidence to the extent necessary for legal reporting and cooperation with investigations. 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, hello-wall greetings, person cards in Plaza, groups, and chat messages, and may block malicious users. Blocking is a measure that prevents the blocked user's KOONG, comments, hello-wall greetings, and chat messages from appearing on the screen of the user who initiated the block, prevents hello-wall greetings left by the blocked user in the blocking user's room from being shown to other users visiting that room as well, and stops notifications to the blocking user about the blocked user's comments, likes, traces, hello-wall greetings, and chat messages (including mentions in chat). In addition, between two users in a blocking relationship, regardless of which of them initiated the block, starting new one-on-one conversations, sending gifts, giving luck, and poking are restricted, the two users are not shown to each other in Plaza, Browse rooms, or user recommendations, and they cannot see each other's MAP on the MY screen (the map of places visited and the passport). The specific effects of blocking are governed by Article 6(4) of the Terms of Service. Because a blocked user can continue to view content that the blocking user has made public, youth users are encouraged to also check their visibility settings.

2. The reasons available for selection when reporting in the app, the Web Chat (the chat interface used in a web browser), or the Desktop App (the application installed on a computer to use the same interface as the Web Chat) are: "Spam or ads", "Inappropriate content", "Harassment or hate speech", "False information", "Privacy violation", "Child safety / minor abuse", "Self-harm or suicide risk", "Violence or threats", and "Other" (entry of a detailed reason is required). Reports made on the grounds of "Child safety / minor abuse", "Self-harm or suicide risk", or "Violence or threats" are classified into the highest-priority queue for urgent review. Material reported under the "Child safety / minor abuse" reason and related records are placed on hold and preserved for 1 year from the date of the report (or, if the report is dismissed after review, until then), regardless of deletion by the uploader or withdrawal from the Service, in accordance with Section 3 of the Child Safety Standards (CSAE) and Article 3 of the Privacy Policy. 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). None of the app, the Web Chat, and the Desktop App currently provides a separate screen for submitting appeals (the "Appeal" button on the account status screen in the app and in the account status window in the Web Chat and the Desktop App opens a screen for composing an email to the above address), 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. A user who has made a report may check the progress and outcome of the report at [Settings > Safety > Report History].

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, a KOONG linked to a nearby place is displayed on the map at the location of that place, 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 KOONG visibility setting for 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. The MAP on the MY screen (the map of places visited and the passport) is initially displayed only to the user themselves. Furthermore, users who have accessed the Service within the last 7 days may be displayed in Plaza regardless of age, and other users may start a one-on-one conversation with them or visit their room from Plaza. A user may turn on "Don't stand in Plaza" under [Settings > Safety > Plaza] so that the user is not displayed in Plaza, in other users' rooms, or in "Active now" recommendations and the user's online indicator is also turned off (the user may still be displayed in user recommendations based on places or trace relationships), and may turn on [Settings > Safety > Hide my room from browsing] so that the user's room is not displayed in Browse rooms or in Room hop in Plaza. Because these settings are initially turned off for youth users as well, youth users and their guardians are encouraged to change them directly as needed.

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.

5. The Company applies the following measures to users who are youth based on the birth year entered at the time of membership registration and to users for whom no birth year information is available. Because these measures are based on the birth year entered by the user, whether they apply may not match the user's actual age, and they are applied in a manner that does not reveal the user's age to other users.

• Such users cannot send or receive coins or items as gifts, or send or receive pokes, with users who are not in a mutual trace relationship with them.

• Such users' rooms are not displayed in the recommendation list of Browse rooms or in "Freshly decorated" in Room hop in Plaza.

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 operate full-time telephone consultation (the phone number shown in the Business Information is a disclosure item required under the Act on the Consumer Protection in Electronic Commerce, Etc.), 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.
