Welcome to MuseBook ("we," "our," or "us"). We are committed to protecting your personal privacy. This Privacy Policy explains how we collect, use, and safeguard your information when you use our AI-powered book reading and summarization application.
To provide the best reading and AI experience, we may collect the following types of data:
Device Information: We collect information such as your device model and operating system version to ensure app compatibility.
Usage Data: We track how you use the app, such as reading duration, features used, and crash logs to improve stability.
Local File Access (Crucial for Functionality): As a reading application, our primary function is to allow you to open and read files (e.g., EPUB, PDF, TXT) stored on your device. We access these files solely to display the content to you within the app and to process them for AI summarization when requested.
We use the collected data for the following purposes:
To scan your device storage and display your personal book library.
To save your reading progress (bookmarks) and preferences.
To synchronize data across multiple devices (if cloud features are enabled).
To detect and fix technical issues (bugs/crashes).
To display relevant advertisements (if the app is ad-supported).
The app requires specific permissions to function correctly:
Internet Access: Required to download book metadata (covers/descriptions), sync data, process AI generation requests, or load advertisements.
We may employ third-party companies to facilitate our service. These third parties have access to your Personal Data only to perform these tasks on our behalf:
Google Firebase: For analytics and crash reporting.
Google Gemini API (Generative AI): We use the Gemini API provided by Google to power the AI features within the application, specifically for our core functionality of summarizing books, answering questions about the text, or translation. When you interact with these features, the text or data you input (your "Prompts") is sent to Google's servers for processing.
We value your trust in providing us with your Personal Information, thus we are striving to use commercially acceptable means of protecting it. However, remember that no method of transmission over the internet is 100% secure.
Our Services do not address anyone under the age of 13. We do not knowingly collect personally identifiable information from children under 13.
