NihonGo is designed to work entirely on your device. Your voice never leaves your phone.
Pitch Karaoke uses the microphone only while you hold the record button. Audio is analyzed on-device in real time to estimate pitch. Recordings are not saved, stored, or transmitted anywhere.
The app itself collects no personal data and requires no account. Learning progress (streaks, scores, settings) is stored locally on your device.
Subscriptions and purchases are processed by Apple. We use RevenueCat to validate purchases; RevenueCat receives an anonymous app-generated identifier and purchase receipts — never your name, email, or voice. See RevenueCat's privacy policy.
