Privacy Policy

Introduction

Pngyu Neue ("we," "our," or "us") is committed to protecting your privacy. This Privacy Policy explains how our PNG compression application handles your information when you use our service.

How Pngyu Neue Works

• Local Processing: All PNG compression occurs locally on your device using the pngquant library
• No Internet Required: The core functionality of Pngyu Neue does not require an internet connection
• Your Images Stay Yours: All input PNG files and compressed output files remain entirely under your control on your device

Data Storage

• Device Storage Only: Any temporary files created during compression are stored locally on your device
• User Control: You have complete control over all input and output files
• No Cloud Storage: We do not store any of your images in cloud storage or remote servers

Third-Party Services

Pngyu Neue may use third-party services for non-core functionality such as:

• Application updates
• Optional ImageOptim integration (if enabled by user)
• Error reporting (if implemented, only technical data without personal content)

Any such services are governed by their respective privacy policies.

ImageOptim Integration

If you choose to enable ImageOptim integration:

• Files are processed by ImageOptim on your local device only
• No data is transmitted over the internet
• This feature is entirely optional and controlled by you

Children's Privacy

Pngyu Neue does not collect any personal information from users of any age. The app is designed to be safe for users of all ages since no data leaves the device.

Changes to This Privacy Policy

We may update this Privacy Policy from time to time. Any changes will be posted on this page and will be effective immediately upon posting. We encourage you to review this Privacy Policy periodically.

Data Security

Since all processing occurs locally on your device:

• We cannot access your images or compressed files
• Your data security depends on your device's security measures
• We recommend keeping your device updated and secured

Your Rights

Since we do not collect or store any personal data:

• There is no personal data to access, modify, or delete from our systems
• All data management is handled directly by you on your device
• You can uninstall the app at any time to completely remove it from your device

Open Source

Pngyu Neue is open source software. You can review the source code at any time to verify our privacy practices and ensure transparency in how the application works. Pngyu Neue is licensed under the GPLv3 license.

This Privacy Policy is governed by the laws of the State of Indiana. Any disputes related to this policy will be resolved in the courts of the State of Indiana.
