9. Children, Age Restriction, and CSAE/CSAM Standards
MeetOnce is intended for users who are at least 18 years old. Users under 18 may not use the service. If we identify an underage account, we may restrict or delete it.
MeetOnce and its developer LUDGI Inc. (주식회사 럿지) explicitly prohibit child sexual abuse and exploitation (CSAE). For these standards, a child means any person under 18 years of age. These standards apply to the MeetOnce app, website, support channels, report handling, and related operational tools.
Prohibited Content and Conduct
- Creating, uploading, storing, sharing, requesting, buying, selling, promoting, or linking to child sexual abuse material (CSAM).
- Sexualizing, exploiting, or endangering children in photos, videos, text, audio, synthetic media, AI-generated imagery, or any other format.
- Grooming, sexual solicitation, coercion, sextortion, trafficking, arranging offline meetings with a child for sexual purposes, or requesting sexual imagery from a child.
- Misrepresenting age or identity in a way that creates a child safety risk.
- Normalizing, concealing, encouraging, or obstructing investigation of CSAE or CSAM.
In-App Reporting and User Feedback
Users can report inappropriate content and accounts through the in-app report action on profiles, the report action in chat rooms, and the block feature. Urgent child safety, CSAE, or CSAM concerns may also be sent to the child safety contact below.
How We Address CSAM
- When we obtain actual knowledge of CSAM or a CSAE risk through reports, operational review, or another source, we promptly restrict, remove, or isolate the content.
- Related accounts may be suspended, permanently banned, blocked, or otherwise restricted depending on the review outcome.
- We may preserve evidence and logs as required by law and may report or cooperate with appropriate authorities, regional reporting bodies, NCMEC (National Center for Missing & Exploited Children), the Korea Communications Standards Commission, law enforcement, and app store safety teams.
- We comply with applicable child safety laws and regulations, including Korean child protection, privacy, and information network laws, laws in the countries where we provide the service, and app marketplace policies.
