This Privacy Policy explains how Chen Jianwei (“we,” “us,” or “our”) handles information when you use the KaiFan mobile application (“KaiFan” or the “App”).

We designed KaiFan to work primarily on your device. We do not require you to create an account to use the App.

1. Information We Collect

1.1 Information stored on your device

KaiFan stores certain information locally on your device, such as:

• Language preference
• Unit preferences (metric/imperial)
• Meal plans, selected recipes, and saved tables
• First-launch date (used to calculate your free trial period)
• Subscription-related flags needed for App functionality

This information stays on your device unless you delete the App or reset your device.

1.2 Purchase information

When you subscribe to KaiFan VIP, Apple processes your payment. We do not receive your full payment card details. Apple may provide us with limited purchase-related information needed to verify subscription status, such as product ID, transaction status, and subscription expiration.

1.3 Information we do not collect

As of the date of this policy, KaiFan does not:

• Require account registration
• Collect your name, email, or phone number through the App
• Track your precise location
• Use third-party advertising or analytics SDKs
