Effective: October 1, 2026 · Version 1.0 · This is an English translation for convenience; the Korean version is the governing text.

Pracsol Inc. ("the Company") provides the EarStep app ("the Service") in compliance with the Personal Information Protection Act of Korea and related laws, and handles users' personal information as described below.

The Service is used without sign-up. We never ask for your name, email address or phone number. The following information is generated or collected automatically while you use the Service.

About the microphone (voice input)

The "answer by voice" feature uses the device microphone. Speech is converted to text by the speech recognition built into your device's operating system (Android/iOS); the Company never receives or stores audio recordings. Only the recognized text is kept on our servers as part of your learning records. The operating system's speech recognition is governed by the privacy policies of the device maker and OS provider (Google, Apple). You can learn with the keyboard without granting microphone permission.

5. Third-party services

6. Your rights

You may at any time request access to, correction or deletion of, or suspension of processing of your learning records. Because the Service does not collect names or emails, please include your "My learning ID" shown at the bottom of the app's Settings screen (the copy button copies the full ID) so we can locate your records. Send requests to the contact below. Deleting the app removes the records on your device, but server records are deleted only on request.

7. Children

The Service is not directed at children under 14 and does not knowingly collect personal information from children under 14. If we learn that a child under 14 has used the Service, we destroy that information without delay.
