ATS is the personal information controller for personal information processed through this website. This Policy applies to website inquiries, quotation requests, product purchase inquiries, and related communications.

This Policy does not apply to third-party websites linked from this website. Please review the privacy policy of each third-party service before providing personal information.

ATS does not request sensitive information or unique identification information through the website inquiry form. Please do not include such information in free-text fields or attachments.

ATS processes personal information only for the following purposes:

• To receive, verify, and respond to product purchase, quotation, service, repair, and general inquiries.
• To communicate with the person who submitted an inquiry and provide requested materials or follow-up support.
• To prepare quotations, review transaction feasibility, and perform steps requested before entering into a contract.
• To maintain website security, prevent misuse, troubleshoot errors, and protect ATS systems and users.
• To comply with applicable legal obligations and establish, exercise, or defend legal claims.

ATS will not use personal information for a materially different purpose without a lawful basis and, where required, separate consent.

ATS processes personal information based on consent, the necessity to take steps at the request of a data subject before entering into or performing a contract, compliance with legal obligations, and other grounds permitted by applicable law.

You may refuse consent to the collection and use of personal information. However, ATS may be unable to receive or respond to an inquiry if information required to identify and contact you is not provided.

When the processing purpose is achieved or the retention period expires, ATS will delete or destroy the relevant personal information without undue delay unless continued retention is required by law.

ATS does not provide personal information to third parties except where the data subject has consented, where provision is necessary under applicable law, or where another lawful ground permits or requires the provision.

If ATS begins regularly providing personal information to a third party, ATS will disclose the recipient, purpose, items provided, retention period, and data subject rights in this Policy or through a separate notice and consent process.

As of the effective date of this Policy, ATS does not separately entrust the processing of website inquiry information to another business or transfer such information outside the Republic of Korea.

If entrusted processing or an overseas transfer becomes necessary, ATS will select and supervise the provider in accordance with applicable law and disclose the provider, entrusted work, destination country, transfer method and timing, items transferred, purpose, retention period, and refusal method before processing begins.

ATS identifies personal information eligible for destruction and destroys it after approval by the responsible privacy personnel. Electronic files are permanently deleted using methods designed to prevent recovery, and paper records are shredded or incinerated.

If information must be retained after the original purpose has been achieved because of a legal requirement, ATS will store it separately and limit access to authorized personnel.

Subject to applicable law, a data subject may request access to, correction or deletion of, suspension of processing of, or withdrawal of consent regarding personal information. A legal representative may exercise these rights where permitted.

1. Send a request to the ATS privacy contact listed below.
2. Provide information reasonably necessary for ATS to verify identity and locate the relevant record.
3. ATS will review and respond without undue delay within the period required by applicable law.

ATS may limit or deny a request only where permitted by law and will explain the reason and available remedy when required.
