We collect the following categories of information:

• Conversation Data: Transcripts and metadata from AI voice conversations conducted through the App. This data is used to display your conversation history and improve the learning experience.

4. Third-Party Services

LinguaAI uses the following third-party services to operate the App. Each has its own privacy policy that governs how they handle your data:

• Clerk (clerk.com/privacy): Manages user authentication, account creation, and session management. Clerk processes your email address and name on our behalf.

8. Data Security

We implement appropriate technical and organizational security measures designed to protect your personal information against unauthorized access, alteration, disclosure, or destruction. These measures include encrypted data transmission (HTTPS), secure backend infrastructure provided by Convex, and access controls limiting who can view your data.

However, no method of transmission over the internet or electronic storage is 100% secure. While we strive to protect your data, we cannot guarantee its absolute security. In the event of a data breach affecting your rights and freedoms, we will notify you as required by applicable law.
