Common questions
I can't sign in
On the sign-in screen, tap Forgot password? and follow the email we send you: it has a link to choose a new password, and a code you can enter in the app instead. If you signed up with Google or Apple, choose the same one again. You don't need a password.
Something isn't working
Check that you are online and have the latest version of Lemba. What you add is kept on your phone and syncs when you are back online. If it still isn't right, contact us with what you did, what happened, and the version of Lemba (at the bottom of Settings).
Lemba shows the wrong class time or venue
Change it where it appears, or tell Lemba what changed. If your class shares its timetable, your class rep can correct it for everyone. Your institution's official timetable always comes first.
I paid for Lemba Pro but it isn't on
Mobile money can take a few minutes. Open Settings and tap Check Pro status. If it still isn't on after an hour, email us with the payment reference. If money left your account and Pro did not start, we will switch it on or refund you. See refunds in the Terms of Service.
Does Lemba Pro renew by itself?
No. Each pass is one payment for a fixed number of days. You are never charged again automatically.
Something in my class is wrong or abusive
Tap the announcement and choose Report. The class's moderators and Lemba will see the report. You can also hide announcements from that person on your phone.
Lemba gave a wrong or offensive answer
Press and hold the answer and choose Report. What you said is only sent if you choose to include it.
Who looks after my class?
Open your class to see who runs it and who the class reps are. If the person running your class has gone quiet or is misusing it, open Who looks after this class on the class page to ask to take over or get help.
I want to stop Lemba sending things to its AI provider
Go to Settings, then Privacy, and turn off Lemba's AI provider. Lemba still answers what it can on your phone.
How do I delete my account?
In Settings, tap Delete account. See Delete your account and data for what is deleted and what is kept, and how to ask without the app.
