Privacy Policy

Last updated: September 15, 2026

This Privacy Policy applies to the JoyuCore website and the EZgolf golf swing analysis app.

Information We Collect

The EZgolf app primarily processes swing videos that you import or record on your device. Videos, images, and body-pose analysis results are stored on your device by default. We do not upload your swing videos to our servers.

The current version of our website and app does not require you to create an account or provide personal identity information such as your name, phone number, or address. If we add registration, login, or membership features in the future, we will update this Privacy Policy in advance and explain what information we will collect and how we will use it.

How We Use Information

We use device information only when necessary to keep the app working, provide version update notices, and perform Google Play Integrity checks. We do not use your swing videos to build user profiles or for advertising.

Third-Party Services

This website may contain links to Amazon, social media platforms, or other third-party websites. Those websites have their own privacy policies, and we are not responsible for their content or privacy practices.

We do not sell, rent, or trade your personal information. We do not actively disclose your personal information to third parties except as required by law or to protect our legal rights.

Data Security

We use reasonable technical and administrative measures to protect the website. The site uses a pure static architecture, HTTPS, and security response headers to reduce the risk of tampering. Because there is no online admin panel or database, website content cannot be modified through a public login interface.
