What we collect

Microphone use

• Audio is analyzed in real time for note and timing detection.
• Raw audio recordings can be kept or discarded per your setting after each session.
• Microphone access is only active during an open practice session.

Uploaded content

Sheet music and MIDI files you upload are used only to generate your own practice reference and are not shared with other users.

Terms of use

By uploading sheet music or a MIDI file, you confirm you have the right to use it for personal practice within Piano.
