We do not directly store sensitive payment instrument data such as card numbers or CVC; such data is handled by Paddle and its payment processors.
| Recipient / Processor | Data | Purpose | Retention | Cross-border |
|---|---|---|---|---|
| Paddle.com | Payment/order data, email | Payment processing, tax, receipts, refunds, billing support | Per Paddle policy | Yes |
| Amazon Web Services, Inc. (AWS) | Service/usage data, logs | Cloud hosting, content delivery, operation | Until end of the outsourcing contract | Yes |
| Google LLC (Google Analytics, Firebase Analytics) | Usage, device, log data | Analytics and service improvement | Up to 14 months | Yes |
| Google LLC / Apple Inc. (social sign-in) | Login identifiers (OAuth) | Authentication | Until account deletion or per provider policy | Yes |
| MongoDB, Inc. (MongoDB Atlas) | Account, content data | Database hosting and storage | Until account deletion or end of the outsourcing contract | Yes |
Because we use overseas providers (e.g., Paddle, cloud, AI APIs, analytics), some personal information may be transferred and processed outside the Republic of Korea. For each provider we will disclose: recipient, country, items transferred, purpose, timing/method, retention/use period, and how to refuse (and the effect of refusing).
The recipients, items, purposes, and retention periods are as listed in the table in Section 4. Transfers occur over encrypted networks at the time you use the service. You may refuse cross-border transfers by contacting us at the email above; however, refusal may make it impossible to provide part or all of the service.
OurVerse is an educational service that may be used by children, typically with a parent's or guardian's involvement. Where a child is below the age of consent under applicable law (e.g., under 14 in Korea), account creation and payment should be carried out by a parent or legal guardian.
We do not knowingly collect personal information directly from children under 14. Accounts and payments must be created and made by a person aged 14 or older, such as a parent or legal guardian. If we learn that personal information of a child under 14 has been collected without the required legal guardian's consent, we will delete it without undue delay.
We will announce material changes to this policy in advance through the service, and the effective date is shown at the bottom of this page.
Effective Date: July 24, 2026
