Privacy Policy

Last updated: July 16, 2026

This Privacy Policy explains how Lingonaut ("we", "us") collects, uses, and protects your information when you use the Lingonaut mobile application (the "App"). By using the App, you agree to the practices described below.

1. Information we collect

We collect information you provide directly, such as your name, email address, chosen learning language, and level. To power conversations, we process the voice recordings and text you submit during practice sessions. We also collect usage data — lessons completed, streaks, and vocabulary saved — to personalize your experience.

2. How we use your information

We use your information to provide and improve the App, deliver personalized lessons and feedback, maintain your progress and streaks, respond to support requests, and send optional practice reminders. Voice recordings are used only to generate real-time responses and pronunciation feedback.

3. Sharing your information

We do not sell your personal information. We share data only with trusted service providers who help us operate the App (such as speech processing and cloud hosting), and only to the extent necessary. We may disclose information if required by law.

4. Data retention & security

We retain your information for as long as your account is active. We use industry-standard safeguards to protect your data in transit and at rest. You can request deletion of your account and associated data at any time.

5. Your rights

Depending on your location, you may have the right to access, correct, export, or delete your personal information, and to object to certain processing. To exercise these rights, contact us at the email below.

6. Children's privacy

Lingonaut is not directed to children under 13, and we do not knowingly collect personal information from them. If you believe a child has provided us data, please contact us and we will remove it.

7. Changes to this policy

We may update this Privacy Policy from time to time. We will notify you of material changes within the App or by email, and the "Last updated" date above will reflect the revision.
