Privacy Policy

Thank you for using Screen Test! We highly value your privacy. This document explains how we handle your data when you use this app.

Information Collection

Screen Test is a professional macOS application that helps you quickly and easily evaluate your display's image quality and visual performance. It includes 25+ test functions to detect dead pixels, backlight bleeding, vertical banding, screen uniformity issues, and more. Suitable for screen testing, display detection, monitor testing, and dead pixel detection scenarios, it's a practical tool for display assessment. All operations are performed locally on your device.

Please Note: This testing tool typically will not cause any damage to your display device, but it cannot replace professional testing equipment. Test results are for reference only.

Important Note: Screen Test operates completely offline. It does not collect, store, or transmit any personal information. The app does not connect to remote servers or integrate any third-party services.

a. Local Data Processing

• All settings and operations are stored only on your local device.
• The app does not record your usage behavior or upload any data.

b. No Logging

Screen Test does not generate or send any logs. All operations and configurations are performed locally, with no remote communication involved.

Use of Data

Since Screen Test does not collect or store any user data, there is no use or sharing of data. All of your usage remains private and offline.

Third-Party Services

Screen Test does not use any third-party analytics tools, advertising platforms, or cloud services, nor does it share or sell user information to any third party.

Data Security

Since all data is stored locally and the app does not communicate externally, all your settings and usage information are protected by the security mechanisms of macOS.
