Privacy Policy

Effective date: November 3, 2026

LH Canvas is an iPad app for drawing and composing sound, developed by Hao Liu. This policy explains how privacy is handled when you use the app.

1. Personal Data

LH Canvas does not require you to create an account. The app does not collect personal information, track users, or use third-party advertising or analytics SDKs.

2. Your Creative Work

Drawings, compositions, project files, and app settings are created and stored on your device. LH Canvas does not automatically upload your creative work to a developer-operated server.

If you choose to export a project, audio file, image, or screen recording, you control where it is saved or shared. Any services you select through the system sharing interface may have their own privacy practices.

3. External Links

LH Canvas may provide links that open Apple's App Store. When you follow an external link, Apple's applicable privacy terms and policies govern your interaction with that service. LH Canvas does not receive your App Store browsing or purchase information through these links.

4. Device Permissions

Certain optional functions, such as screen recording, may use Apple-provided system interfaces and permission prompts. You decide whether to use those functions. LH Canvas does not automatically send recordings to the developer.

5. Children's Privacy

LH Canvas does not knowingly collect personal information from children or other users.

6. Changes to This Policy

If the app's data practices change, this policy will be updated to reflect those changes. The current version will be available on this page.

7. Contact

For privacy-related questions, please contact the developer through the official contact page.
