Privacy Policy

Effective date: 24 July 2025

1. Developer Information

Mangekyou Studio is developed and published by Zhuo Yin ("we", "us", or "our"). If you have any privacy-related questions, please email us at support@mangekyou.app.

2. We Do Not Collect Personal Data

The App runs entirely on your device and stores all prompts, settings, and generated images locally. We do not collect, transmit, or store any personal data or usage analytics.

3. Crash Reports & Apple Analytics

If you have opted in to share crash reports or anonymous analytics with Apple, Apple may collect device and usage information to improve its products and services. We do not receive or process this information.

4. Children's Privacy

The App is not intended for children under 13 years of age. We do not knowingly collect personal data from anyone under 13. If we learn that we have inadvertently received such data, we will delete it immediately.

5. Data Security

Because all data remains on your device, its security depends on the safeguards you apply (e.g., device passcode, disk encryption, iCloud backups). We recommend enabling the security features provided by your operating system.

6. Third-Party Services

The App connects to Third-Party Services you configure (e.g. Stable Diffusion WebUI servers or NovelAI accounts). We do not control how those services handle data. Please review their respective privacy policies.

7. Changes to This Policy

We may update this Privacy Policy from time to time. Any material changes will be communicated within the App or on our website. Continued use after changes become effective constitutes acceptance of the revised Policy.
