Q. My study history disappeared. What should I check?

A. If you have not linked a login method, history may only be stored in the current browser or device. Check whether you changed browsers or cleared browser data.

Q. How do I link a login method to protect my history?

A. Open the user menu inside the app and choose the login/link option. Linking makes it easier to recover your history when you use another device or browser.

Q. What is Teacher Review?

A. Teacher Review is pronunciation feedback from a teacher. After you submit a recording, the teacher checks pronunciation, intonation, and points to improve. The number of submissions depends on your plan.

Q. My Teacher Review reply or ticket count looks wrong. What should I send?

A. Email us with your login email, approximate submission time, lesson location, and the ticket count shown on screen. We will check the submission and plan state.

Q. How do I change my plan or check billing?

A. Check your current plan from the plan or account page in the app. Upgrades usually take effect immediately, while downgrades or cancellations apply after the current billing period. Contact us if a payment fails or the displayed plan looks incorrect.

Q. How do I report a mistake in a lesson, translation, or audio?

A. Use the Flag button in the bottom-right corner of the screen. Include the lesson name, the location of the issue, and what you saw or heard so we can check it faster.
