Privacy Policy

Information we collect

Account information

When you create an account, we collect:

• Email address
• Display name (if provided)
• Authentication credentials via Google Sign-In, Apple Sign-In, or email/password

Learning data

As you use the App, we store:

• Lesson completion records (which lessons you've completed, scores, time spent)
• Vocabulary progress and spaced repetition state (familiarity levels, review schedule)
• Streak and daily activity data

Audio recordings

When you use the speak-and-repeat feature, your voice is recorded on your device and sent directly to Google Cloud Speech-to-Text for processing. We do not store your audio recordings. Google processes the audio transiently to return a transcript and discards it according to their data processing terms.

Analytics data

We use PostHog to collect anonymous usage analytics, including device type, operating system, screen size, app version, and how you interact with the App. This helps us understand usage patterns and improve the experience. PostHog may collect device-level identifiers for analytics purposes.

We also use PostHog session replays to record a sample of user sessions. These replays capture interactions such as taps and scrolls to help us understand how people use the App and improve the experience. Session replays do not capture any personally identifiable information, keystrokes in input fields, or passwords. Recordings are automatically deleted after 30 days.

Crash reports

We use Firebase Crashlytics to collect crash reports and diagnostic data. This includes device model, OS version, and stack traces when errors occur. Crash data is used solely to identify and fix bugs.

How we use your information

We use your information to:

• Provide and operate the App, including saving your learning progress
• Authenticate your identity and maintain your account
• Track your streaks and spaced repetition schedule
• Analyze usage patterns to improve the App
• Diagnose and fix technical issues

Third-party services

The App uses the following third-party services that may process your data:

• Supabase — Authentication, database, and data storage (privacy policy)
• Google Cloud Speech-to-Text — Voice recognition for pronunciation exercises (privacy notice)
• Google Sign-In / Apple Sign-In — Account authentication
• PostHog — Product analytics (privacy policy)
• RevenueCat — Subscription management and purchase validation (privacy policy)
• Firebase Crashlytics — Crash reporting (privacy policy)

We do not sell, rent, or share your personal information with third parties for marketing purposes.

Data storage and security

Your data is stored on Supabase's cloud infrastructure. We use industry-standard security measures, including encrypted connections (TLS) and secure authentication, to protect your data. However, no method of electronic storage is 100% secure, and we cannot guarantee absolute security.

Data retention

We retain your account and learning data for as long as your account is active. If you delete your account, we will delete all your personal data within 30 days, except where retention is required by law.

You have the right to:

If you are a parent or guardian and believe your child has provided personal information that concerns you, please contact us and we will take steps to remove that information.

Changes to this policy

We may update this privacy policy from time to time. We will notify you of significant changes through the App or by email. Continued use of the App after changes constitutes acceptance of the updated policy.
