1. Significance of the Privacy Policy

This Privacy Policy has been prepared based on the Personal Information Protection Act. We have made every effort to explain the status of user personal information processing within Mummu in the most detailed and easy-to-understand manner possible. This involves the adoption of the "Plain Language Privacy Policy" principle, which aims to draft policies using simple and accessible terminology.
This Privacy Policy holds the following important meanings:
• Transparency of the 'Life Cycle of Personal Information': It transparently provides information regarding what data Mummu collects, how the collected information is used, with whom it is shared (consignment or provision) as necessary, and when/how information is destroyed once the purpose of use is achieved.
• Information on User Rights: It informs users, as data subjects, of their rights regarding their personal information and the methods and procedures for exercising those rights. Additionally, it provides guidance on the rights legal representatives (such as parents) can exercise to protect the personal information of children under the age of 14.
• Response to Infringements: It informs users whom to contact and what help is available to prevent further damage and recover from existing damage in the event of a personal information breach. Most importantly, it serves as a means to guarantee the user’s "right to self-determination of personal information" by defining the relationship of rights and obligations between Mummu and its users.
