This Policy applies commonly to the Company's Services. The Services are provided primarily to organizations such as institutions, companies, and schools, and login accounts (administrator codes) are issued to administrators and instructors. Trainees who take part in practice sessions use the Services without a separate account and are data subjects. Where the Company processes the personal information of an institutional customer's employees or trainees at that customer's request, the Company does so only for that customer and within the scope of its purposes, and the institutional customer determines whether and to what extent such personal information is collected and used.

Of these, information with identifying potential, such as an employee number, is stored in encrypted form. Methods of collection: entry and automatic collection during use of the Services and devices, website inquiries, and provision by institutional customers.

The Company uses collected information for the following purposes. - Synchronizing and aggregating training results, providing dashboards and reports, and monitoring and remotely managing devices - Identifying and authenticating members and managing accounts and licenses - Providing training performance and completion status to institutional customers - Improving the Services, analyzing statistics, diagnosing errors, and responding to inquiries - Fulfilling obligations under applicable law

However, the following information is retained as set out below. - Account information: retained during the period of service use and of the contract, and destroyed upon termination of the contract or upon a destruction request by the institution or data subject - Training and result data: because providing access to and reporting of training history and statistics over the entire period is an essential function of the Services, retained while the Services are operated, and destroyed upon termination of the contract with the institution, where required by law, or upon a destruction request - Other information: where retention is required by applicable law (such as the Act on Consumer Protection in Electronic Commerce and the Protection of Communications Secrets Act), retained for the relevant period

Personal information is destroyed once the retention period has elapsed or the purpose of processing has been achieved. Electronic files are deleted by methods that make recovery difficult, and printed materials are shredded or incinerated.

The Company does not provide personal information to any external party except with the consent of the data subject or where there is a legal basis. However, under agreements with institutional customers, the Company may provide training completion information (identifier, completion status and time, etc.) to the relevant institution or to an education management system designated by that institution, in which case it is limited to the scope for which the necessary consent is obtained or a legal basis exists.

To provide the Services reliably, the Company entrusts personal information processing tasks to domestic and overseas providers as set out below, and some personal information is transferred overseas. Principal data such as training results is stored domestically (Seoul).

- Time and method of transfer: transferred from time to time over the information and communications network at the time the Services are used - Purpose of use and retention/use period: until the purpose of each task above is achieved or the entrustment agreement is terminated - The data subject may refuse some of the above entrustment/transfer (such as statistical and behavioral analysis and error diagnostics) through cookie and device settings. However, entrustment/transfer essential to providing the Services, such as data storage and hosting, is by its nature difficult to refuse individually, and refusal may restrict the use of all or part of the Services. - The specific details of entrustment and transfer will be announced through this Policy if changed.

Data subjects may at any time request access to, correction of, deletion of, or suspension of processing of their personal information, and may withdraw consent.
