Introduction

Welcome to ReadingKulture ("we," "our," or "us"). We are committed to protecting your privacy and ensuring you have a positive experience when using our mobile application ("App"). This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use our 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.

Information We Collect

Information You Provide

  • Google Account Information: When you sign in with Google, we receive your name, email address, and profile picture from your Google account. This is used solely to provide cloud sync functionality.
  • User Content: The e-books you import, bookmarks you create, highlights and annotations you make, and reading preferences you set are stored locally on your device.

Information Collected Automatically

  • Usage Data: We collect anonymous usage statistics through Firebase Analytics, including which features you use, how often you use the App, and general app performance data.
  • Device Information: We may collect information about your device type, operating system version, and unique device identifiers for analytics purposes.

Information We Do NOT Collect

  • We do NOT read the content of your e-books
  • We do NOT track your reading habits or book preferences
  • We do NOT sell or share your personal information with third parties for marketing purposes

How We Use Your Information

We use the information we collect for the following purposes:

  • To provide and maintain the App's functionality
  • To enable cloud sync of your library through Google Drive
  • To provide AI-powered book summaries (see AI Features section below)
  • To improve and optimize the App's performance
  • To analyze usage patterns and improve user experience
  • To respond to your inquiries and provide customer support

AI-Powered Features

AI Book Summariser

ReadingKulture offers an optional AI-powered book summarization feature. When you use this feature:

  • What is sent: Extracted text content from your book is sent to Google's Gemini AI API to generate a summary. Only the text needed for summarization is transmitted.
  • Anonymity: Requests are fully anonymous — no user ID, account information, or personal data is attached to AI requests.
  • No server storage: We do not store your book content on any server. The text is transmitted directly to Google's AI service and is not retained by us.
  • Local caching: Generated summaries and follow-up conversations are cached locally on your device in SQLite for offline access.
  • Rate limiting: The feature is limited to 1 book summary per 24 hours to keep the service free for all users.

Highlights & Annotations

Text highlights and annotations you create in the EPUB & PDF reader are stored exclusively on your device's local database. They are never transmitted to any external server unless you choose to back up your library via Google Drive sync.

Data Storage and Security

Local Storage

Your e-books, bookmarks, and reading progress are stored locally on your device using secure storage mechanisms. This data remains on your device unless you choose to sync with Google Drive.

Cloud Storage

If you enable Google Drive sync, your library data is stored in your own Google Drive account in a dedicated folder. We do not have access to your Google Drive; the sync happens directly between your device and your Google account.

Security Measures

We implement appropriate technical and organizational security measures to protect your information. However, no electronic transmission or storage system is 100% secure, and we cannot guarantee absolute security.

Third-Party Services

Our App uses the following third-party services:

  • Google Sign-In: For authentication and identity verification. Google Privacy Policy
  • Google Drive API: For cloud storage and sync functionality. Google Privacy Policy
  • Firebase Analytics: For anonymous usage analytics. Firebase Privacy Policy
  • Google Gemini AI: For AI-powered book summaries (optional feature). Requests are anonymous and content is not retained. Google AI Terms
