Privacy Policy

Effective Date: June 26, 2025

Version: 1.0


1. Introduction

StatDataViewer (the “App”) is developed by Xiaoguang Yan. Your privacy is important to us. This Privacy Policy explains how the App handles any data (if any) and describes your privacy rights.

2. Information We Do Not Collect

  • The App does not collect, transmit, or store any personal or usage data.
  • All data processing is performed locally on your device; no data is uploaded to any servers.

3. Local Data Storage

  • Any files or datasets you open with the App remain on your device unless you explicitly share or export them.
  • The App may save user preferences or settings locally (e.g., window positions, view options) using system‑provided mechanisms (e.g., UserDefaults).

4. Third‑Party Services

  • The App does not integrate with any third‑party analytics, advertising, or crash‑reporting services.
  • No external libraries in the App transmit data over the network.

5. Security

  • We follow industry best practices to secure the App’s code and local data storage.
  • The App uses macOS sandboxing to restrict file system and network access.

6. Children’s Privacy

  • The App is not intended for use by children under 13.
  • We do not knowingly collect information from children under 13.

7. Changes to This Privacy Policy

We may update this Privacy Policy from time to time. When changes are made, we will update the Effective Date above. Continued use of the App after such changes constitutes acceptance of the new policy.
