Please don't include passwords or other personal information that we don't need to handle your request.

Do I need to sign up?: No. An anonymous account is created automatically when you open the app. On iPhone, you can optionally link your account with Sign in with Apple in Settings.
Where is my learning data stored?: Your learning history, Notebook, House, and settings are stored on your device. When you use AI features, the audio or text needed for that request is sent through our servers to OpenAI. See the Privacy Policy for details.
Are my voice recordings saved?: Not on our servers. Audio is sent to OpenAI for transcription, and the file on your device is deleted after processing.
Can I use the app offline?: Notebook review works offline. AI features such as Smart Speak need an internet connection.
Which languages can I practice?: You can practice English, French, Korean, Japanese, and Spanish. The app itself, including its explanations, can be set to Japanese or English.
How do I delete my data?: Data on your device is deleted when you delete the app. To ask us to delete your account and the data on our servers, contact hello@sozorostudio.com. To verify your identity, we may ask you for information such as the device you use and when you used the app.
