Frequently asked questions
Which devices and system versions are supported?
iPhone and iPad with iOS / iPadOS 16.4 or later.
Do I need an account?
No. Without signing in, you can use the library, practice, recording and review features on your device as a local guest. Cloud sync, sharing and score recognition require an account.
How do I sign up and sign in?
Go to Me > Account, sign up with your email address, and verify it using the email we send you. Then you can sign in. Passwords must be 6–20 characters long.
I didn't receive the verification email. What should I do?
Check that the address is correct and look in your spam folder. You can also choose "Resend verification email" on the Account screen. If it still doesn't arrive, email us.
I forgot my password.
On the Account screen, choose "Recover password" and follow the instructions in the email to set a new one.
Do I need an internet connection to practice?
Scores downloaded to your device can be practiced, recorded and reviewed offline. Signing in, cloud sync, sharing and score recognition need a connection.
Are my practice recordings uploaded?
Not automatically. Microphone audio is analyzed on your device, and practice recordings and history stay on your device by default. Images or PDFs are uploaded to our server only when you start score recognition yourself.
The app can't use the microphone or camera.
Score following needs microphone access, and photo recognition needs camera or photo library access. Open the iPhone Settings app, find 弦动 and turn on the permission, or go to Me > Privacy and data in the app and tap "Open system permission settings".
I got a new device. What happens to my data?
Cloud scores download automatically when you sign in on the new device. Scores, drafts, practice records and settings stored on the old device can be exported with Me > Local backup and restored on the new one; you can choose whether to include recordings. Backup files are not encrypted, so keep them somewhere safe.
How do I change my password or email?
Go to Me > Account and choose "Change password" or "Change email". Afterwards, every device needs to sign in again.
How do I delete my account?
Go to Me > Account, choose "Delete account", enter your password again and confirm. The account is disabled immediately, every device is signed out, and this account's scores, drafts, recordings and settings are removed from the device. Online data is deleted within 24 hours, and backups are kept for at most 30 days. This cannot be undone. You can also request deletion by emailing admin@zhuqutech.com. See our Privacy Policy for details.
