2. Purposes of collection and use

Understanding service readiness for merchants (launch regions and business categories)

Evidencing consent for app members — confirming when, and to which version, a member agreed to the Terms of Service and to the collection and use of personal data (Article 13 of the Act on Consumer Protection in Electronic Commerce)

We do not use the data for any purpose beyond the above. Marketing messages are sent only to those who have opted in, and consent may be withdrawn at any time.

3. Retention and use period

As a rule: destroyed without delay once the enquiry has been handled
Where a registrant proceeds to a merchant agreement, we obtain separate consent and inform them again of the retention period for that purpose.
Where retention is required by law, the data is kept for the period prescribed.

4. Outsourcing and overseas transfer

We entrust the following processing, and the servers of these processors may be located outside Korea.

Processor	Entrusted work	Items · country
Google LLC	Storage of form responses (Google Forms)	Items in section 1 · United States and other countries where Google data centres are located

5. Right to refuse consent
