Privacy Policy

Last updated: April 21, 2026

Hai Yang (“we”, “us”, or “our”) operates the mobile application ChronoFable (the “App”). This Privacy Policy explains how we collect, use, and protect your information when you use the App.

By using the App, you agree to the collection and use of information in accordance with this policy.

1. Information We Collect

1.1 Information You Provide

When you use ChronoFable, you may provide:

• Any text you type into the App when starting a simulation (your “prompt” or “input”), such as your situation description and questions.
• Optional account information if you choose to sign in (e.g., Sign in with Apple). If you use Sign in with Apple, we may receive a stable Apple-provided identifier for your sign-in within this App. We do not require sign-in to use the core simulation features.

1.2 Automatically Collected Information

We may collect limited technical information, such as:

• Device model, operating system version, language, and app version.
• Basic usage information (e.g., feature interactions and error diagnostics). This information is used only to operate, troubleshoot, maintain, and improve the App.

1.3 Identifiers Used for Service Operation

To provide the service and manage usage credits, the App uses:

• A pseudonymous, app-generated user identifier (“user_id”) used for quota/credits management. This identifier is not your real name.

2. How We Use Your Information

We use the collected information to:

• Generate simulation results and related content based on your input.
• Manage usage credits and enforce quota limits.
