When you use our products and services, we may collect the following information: audio recordings of your speech (processed locally on your device or server), account information such as email address and username, usage data including practice frequency and performance metrics, and technical data such as device type and browser version.
We use the collected information solely to provide and improve our pronunciation training services. Your audio recordings are only used to generate feedback and recommendations. We do not sell, rent, or share your personal data with third parties.
All data is stored on your own server when using our on-premise deployment option. For our cloud service, data is stored in secure, encrypted databases. We implement industry-standard security measures to protect your information.
You have the right to access, correct, or delete your personal data at any time. Contact us to exercise these rights.
