The app records nothing, and sends no audio to us.
It listens through your phone's speech recognition: Apple's on iPhone, the phone's speech service on Android (usually Google's). With a connection your phone may send the audio to that service to be recognised, under Apple's or Google's privacy policy; without one, it is recognised on the phone.
If you have an account, we keep your answer history — which word, when, how long you took and the grade — but no recordings and no transcripts of what you said.
