Privacy Policy

Last updated: September 18, 2026

StemTune is designed to process audio directly on your device.

Data collected

StemTune does not collect, transmit, sell or share personal data, usage data or audio content with PCE Business or third parties.

Audio files

Songs selected by the user are copied and processed locally to generate instrument tracks. Files remain on the device and can be deleted by the user. StemTune does not upload audio to servers.

Music library

When the user imports a song, iOS may request access to the media library. This access is used only to let the user select a track and process the audio on the device.

Purchases

Subscriptions and purchases are processed by Apple. StemTune receives only the status needed to unlock purchased features. Apple may handle payment information under its own privacy policy.

Preferences

The app stores preferences such as language, free plan usage and mixer settings locally. This information does not leave the device.

Children

StemTune is not specifically directed at children and does not knowingly collect children's personal data.
