Privacy Policy

Last updated: January 7, 2025

Introduction

Lingbro ("we," "our," or "us") is committed to protecting your privacy. This Privacy Policy explains how we collect, use, disclose, and safeguard your information when you use our mobile application for language learning and practice.

Information We Collect

Personal Information:

We may collect minimal personally identifiable information such as your email address if you choose to create an account for syncing your progress across devices.

Voice and Audio Data:

Lingbro processes your voice recordings locally on your device for pronunciation practice. We do not upload, store, or transmit your voice recordings to our servers. All speech recognition and processing happens entirely on your device.

Learning Progress Data:

Your language learning progress, including lesson completion, vocabulary mastery, and practice statistics are stored locally on your device. If you create an account, this data may be synced to our secure servers for backup and cross-device access.

Usage Data:

We may collect anonymized analytics data to improve the app experience, including lesson completion rates and feature usage. This data cannot be linked back to individual users.

Local Storage:

The app stores your preferences locally on your device, including:

  • Learning progress and lesson completion
  • Vocabulary lists and flashcards
  • App settings and preferences
  • Downloaded lessons and language packs
  • Practice history and streak tracking

How We Use Your Information

We use collected information to:

  • Provide personalized language learning experiences
  • Track and display your learning progress
  • Generate AI-powered lessons and feedback
  • Sync your data across multiple devices (if opted in)
  • Improve app features and user experience
  • Remember your app preferences and settings

Data Sharing and Disclosure

We do not sell or trade your personal information. Your voice recordings remain on your device and are never uploaded to our servers.

If you opt-in to account creation, your learning progress data may be stored on secure servers for synchronization purposes only.

We may disclose information if required by law or to protect our rights, property, or safety.

Data Security

Your voice recordings and practice sessions remain on your device. Learning progress data that is synced to our servers is encrypted both in transit and at rest. While we take steps to protect your information, no method of electronic storage is 100% secure.

Data Retention

Your learning data and app preferences are stored locally until you delete the app or reset your settings. If you create an account, your synced data remains on our servers until you request deletion or delete your account.

Children's Privacy

Our app is suitable for ages 4+ and may be used by children under parental supervision. We do not knowingly collect personal information from children under 13 without parental consent. If you are a parent or guardian and believe your child has provided us with personal information, please contact us.

Third-Party Services

Lingbro uses minimal third-party services for:

  • Cloud synchronization (if account is created)
  • Anonymized analytics to improve the app
  • Payment processing for premium features

All third-party services comply with applicable privacy regulations and do not have access to your voice recordings or personal learning content.

AI and Machine Learning

Our AI-powered features use on-device machine learning models to provide personalized lessons and pronunciation feedback. No personal learning data is sent to external servers for AI processing.

App Store Compliance

Lingbro complies with both Apple's App Store and Google Play Store guidelines and privacy requirements:

  • Minimal data collection with user consent
  • No sharing of personal data with third parties
  • Local-first data processing for voice and practice
  • Transparent privacy practices
  • Cross-platform consistency

Your Rights

You have the right to:

  • Access your data (stored locally on your device)
