Privacy Policy

Effective Date: January 18, 2026

Welcome to Billy. This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use our mobile application ("App"). Please read this privacy policy carefully. If you do not agree with the terms of this privacy policy, please do not access the App.

1. Information We Collect

1.1 Information You Provide

Currently, Billy does not require user registration or authentication. However, if you choose to interact with the App, we may collect:

• Chat Interactions: When you chat with Billy, the text of your messages is processed to generate responses.
• Voice Input: If you use the microphone feature, your voice data is processed to convert speech to text. Audio recordings are not stored, saved, or used for advertising or profiling purposes.

1.2 Automatically Collected Information

When you use the App, we may automatically collect certain information, including:

• Device Information: Device type, operating system version, and device identifiers
• Usage Data: Information about how you interact with the App, including features used, interaction patterns, and in-app progress (such as coins or mini-game progress, if applicable) to help us improve the user experience
• Analytics Data: We use Firebase Analytics (provided by Google) to collect anonymous usage statistics to improve our App
• Log Data: Technical information such as app crashes, errors, and performance data

1.3 Third-Party Services

The App uses Firebase (provided by Google) and OpenRouter (AI Model Aggregation) for backend services, which may collect additional information. Please refer to their respective Privacy Policies for more details.

2. How We Use Your Information

We use the information we collect to:

• Provide, maintain, and improve the App and its features (including the Chat and Mini-Games)
• Analyze usage patterns to understand how users interact with the App
• Debug technical issues and improve App performance
• Remember your preferences (like background images and game progress)

3. Data Storage and Security

3.1 Local Storage

Game progress (coins, levels, high scores) and customization preferences are stored locally on your device using AsyncStorage. This data is private to your device and is not automatically synchronized with our servers.

3.2 AI Processing (OpenRouter)

To generate intelligent and conversational responses, the text of your chat messages is transmitted to OpenRouter.

• Transient Nature: This data is used solely to generate a response.
• Reference: Please review OpenRouter's Privacy Policy.

3.3 Security Measures

We implement appropriate technical and organizational measures to protect your information. However, no method of transmission over the Internet or electronic storage is 100% secure. While we strive to use commercially acceptable means to protect your information, we cannot guarantee absolute security.

4. Data Sharing and Disclosure

We care about your data privacy. We share data only in the following circumstances:

• Service Providers: We use OpenRouter (for AI) and Firebase (for Analytics/Config). These providers have access to necessary information to perform their functions.
• Legal Requirements: We may disclose information if required by law or in response to valid requests by public authorities.
• Business Transfers: In the event of a merger, acquisition, or sale of assets, user information may be transferred as part of that transaction.

5. Children's Privacy

Our App is designed for a general audience. We do not knowingly collect personal information from children under the age of 13. We are committed to complying with the Children's Online Privacy Protection Act (COPPA).

• We do not require users to create an account or provide personal contact information (like email or phone number).
• Voice data is processed transiently for interaction purposes only.
• If you believe we have inadvertently collected personal information from a child under 13, please contact us so we can delete it.

6. Changes to This Privacy Policy

We may update this Privacy Policy from time to time. We will notify you of any changes by posting the new Privacy Policy on this page and updating the "Effective Date" at the top. You are advised to review this Privacy Policy periodically for any changes.
