Kids do not type a name. Sign in uses the TechWorks code and PIN. The name comes back from TechWorks. Signed out, the song stays on this Chromebook and no mark is sent.
The microphone is off unless a student taps Use the mic once, then Start the loop. It listens for one loop, about eight seconds at most, then the mic turns off. That loop is not saved on the Chromebook and is not sent to an account. Download keeps a copy only if the student taps Download. Delete throws it away. Saying no leaves the pads working.
Sound can stay off. Nothing is sent to an account.
