Information stored by the app

Ear Training stores practice progress and preferences locally on the device. This includes exercise identifiers, right and wrong results, mastery and streak calculations, session dates and durations, accessibility choices, response-time settings, and the selected instrument.

The app does not intentionally store recognized words or retain microphone recordings as part of practice history. Deleting the app normally removes its local data, subject to device backup settings.

Microphone and speech recognition

Microphone access is optional and is requested for hands-free answers, voice commands, and pitch-production exercises. Where available, learners can use tap controls instead and can revoke permission in system settings.

Spoken answers are recognized through the service selected by Android or iOS. Depending on the device, settings, installed service, language, and network, audio and results may be processed on-device or by the platform provider. HartmannTek does not operate a speech-processing server.

Pitch exercises analyze microphone samples in memory to estimate pitch. The current implementation does not intentionally retain or upload a recording.

Audio, network use, and diagnostics

Lesson narration and musical examples are bundled with the app. The current app does not include advertising, behavioral analytics, user accounts, or cloud synchronization operated by HartmannTek.

A bounded diagnostic event buffer helps identify audio and speech failures. It remains in application memory, is cleared when the process ends, does not transmit events, and redacts common sensitive values.

Children and changes

The beta is not presently offered as a child-directed online service and does not knowingly collect children's personal information through an application-operated server. Store age-rating and family-policy requirements will be reviewed before public distribution.

Material changes to data handling will be reflected here with a new date. Questions may be directed through the HartmannTek support page.
