What the app stores
MIDI files, pieces and participant labels are processed and stored on your device. The library keeps internal recovery copies. We do not operate a user account service or a music upload service.
Connectivity and purchases
The app has no advertising or analytics. Its StoreKit integration can request products, make and restore purchases, and verify access with Apple. Apple processes payment and provides signed transaction information; we do not receive your card details. Technical preparation does not mean the product has been released.
Backups and deletion
When you share a JSON file, you choose its destination in the system share sheet. The file contains your rehearsal data in readable form. Deleting a piece removes its internal recovery copies. Uninstalling the app removes the local library. Manage exported files and device or iCloud backups separately.
Contact and other services
If you open a support link or email us, this website’s privacy notice also applies. Apple and the file destinations you choose have their own privacy practices.
Who to contact
NÚCLEO is the brand used for these projects by Gonzalo Juarez Martin. For questions about this notice or information you have sent us, email hello@nucleo.build.
Email does not automatically receive data stored in the apps. Manage exported copies and backups with their respective providers.
