1. Information We Collect

1.1 Personal Information

When you create an account, we collect personal information that you voluntarily provide to us, such as your name and email address. We use Google Sign-In for authentication, so we receive your basic profile information from Google.

1.2 Audio Data

To provide pronunciation feedback, our app requires access to your device's microphone. When you record your voice:

  • Your audio is recorded locally on your device.
  • The audio data is transmitted to Microsoft Azure Cognitive Services for the sole purpose of analyzing your pronunciation and generating a score.
  • We do not permanently store your voice recordings on our servers.

1.3 Usage Data & Crash Reports

We may collect non-personal information about how you access and use the app. We use Sentry to collect error logs and crash reports to help us improve the stability of the application.

1.4 Conversation Data

When you use the Exam or Practice features, the text transcript of your speech is processed by Google Gemini API to generate conversational responses and evaluate your language proficiency.

2. How We Use Your Information

We use the information we collect to:

  • Provide, operate, and maintain our app.
  • Authenticate your identity.
  • Provide pronunciation assessment features.
  • Improve, personalize, and expand our app.
  • Find and prevent fraud.

3. Third-Party Services

We use the following third-party services:

  • Supabase: For authentication and database services.

  • Sentry: For error tracking and performance monitoring.

These third parties have access to your Personal Information only to perform these tasks on our behalf and are obligated not to disclose or use it for any other purpose.

4. Data Security

We value your trust in providing us your Personal Information, thus we are striving to use commercially acceptable means of protecting it. But remember that no method of transmission over the internet, or method of electronic storage is 100% secure and reliable, and we cannot guarantee its absolute security.
