Privacy Policy

Effective: 2026-05-15 · Version 1.0

Summary: wondercanvas collects the minimum personal data needed to deliver the service. See the sections below for details.

1. Purpose

This policy explains how the operator of the wondercanvas app (the "App") handles user data. It is written in line with the spirit of Korea's Personal Information Protection Act (PIPA), the US Children's Online Privacy Protection Act (COPPA), and the EU General Data Protection Regulation (GDPR).

2. Personal Data We Collect

Specific items collected are disclosed on request. Contact the operator listed below for the exact items and purposes.

3. Data Stored On Your Device

The app stores the following data only on the user device. It is not transmitted off-device and cannot be used to identify an individual.

  • App settings

These items are stored in device-local storage; uninstalling the app permanently deletes all of them.

4. Network and Server Communication

The app communicates with external servers to deliver its features. Data transmitted is handled under the "Personal Data We Collect" and "Third-Party Services" sections of this policy.

5. Third-Party Services

The app uses the following third-party services:

  • Supabase (parent/child accounts, database, file storage)
  • Anthropic Claude (3Q dialogue-generation AI)
  • Google Gemini / Imagen (image-generation AI)
  • OpenAI (text-to-speech, TTS)
  • Speech-to-text (STT) service

Each provider may apply its own privacy policy in addition to this one.

6. Cross-Border Transfer of Personal Data

The operator transfers personal data abroad as set out below (PIPA Article 28-8). You may refuse the cross-border transfer; if you do, features that depend on it may be limited.

Recipient Country Items Transferred Purpose
Anthropic, PBC United States Child and caregiver conversation text (spoken content) Socratic 3Q dialogue generation and safety filtering

7. Advertising and In-App Purchases

The app does not display advertisements. The app does not offer in-app purchases.

8. Children’s Privacy

wondercanvas carries an App Store age rating of 4+ and is directed to children.

COPPA Compliance

When collecting personal data from children under 13, the operator obtains verifiable parental consent.

Korean PIPA

PIPA Article 22(6) requires legal guardian consent when processing personal data of children under 14. As this app does not process personal data, that provision does not apply.

9. Your Rights

You have the right to access, correct, delete, or request a halt to the processing of your personal data. Contact the operator below.

10. Response to a Data Breach

If the operator becomes aware of a personal-data breach, it will notify affected users within 72 hours — describing the items breached, when and how it occurred, steps to minimize harm, the operator’s response, and where to report — and will report it to the Personal Information Protection Commission or the Korea Internet & Security Agency (KISA), per PIPA Article 34.

11. Security

The operator protects user data with reasonable technical and administrative measures, including transport-layer encryption (TLS) and access controls at rest.

12. Changes to This Policy

When this policy changes, the operator will notify users through an app update and this page. Changes take effect on the stated effective date.

13. Chief Privacy Officer

In accordance with PIPA Article 31, the operator designates the following Chief Privacy Officer, who oversees personal-data handling and responds to user inquiries and complaints.

You may also report privacy concerns to Korea’s Privacy Infringement Report Center (privacy.kisa.or.kr, 118) or the Personal Information Dispute Mediation Committee (kopico.go.kr, +82-1833-6972).
