Frequently asked questions
Does uninstalling the app delete my account?
No. Uninstalling does not delete the Firebase account or server-stored learning records. Follow the Account & Data Deletion instructions.
I cannot register or sign in.
Check the parent-managed email address, password, and internet connection. If the email is already registered, sign in or request a password reset. After completing email verification in a browser, return to the app and sign in again so that it refreshes the verification state.
I forgot my password.
Select Reset password on the sign-in screen and follow the email sent to the registered address. Check the spam folder if necessary.
Why is a result missing on another device?
Confirm that both devices use the same account and reconnect to the internet. Guest records are not synchronized to other devices.
Must I enter the learner's real name?
No. Use a nickname and avoid a school, class, telephone number, or other identifying information.
