Frequently asked questions
I forgot my password
On the sign-in screen, tap Forgot password? and enter your email. We send you a reset link; open it and choose a new password. If the email does not arrive within a few minutes, check your spam folder.
How do I delete my account?
In the app, go to Settings → Delete account and confirm with your password. Your account is deleted after a 30-day grace period, during which you can sign in and cancel. If you cannot sign in, email us from the address on your account. Deleting your account does not cancel an App Store or Google Play subscription.
Can I get a copy of my data?
Yes. Go to Settings → Privacy → Download my data. We email a download link to your account address, normally within 72 hours. The link works for 7 days, and you can request a copy once every 7 days.
Speaking or AI conversation does not work
Speaking practice uses your phone's speech recognition: allow Microphone and Speech Recognition for Langle in your phone's settings, and make sure Korean is available. AI conversation runs on your iPhone with Apple's on-device model, so it needs a supported iPhone with Apple Intelligence turned on.
