KT Multitracks privacy
Updated October 24, 2026. This page describes the native Mac and iPad beta operated by Kulinich Tech.
Your audio and local library
The app stores downloaded songs, prepared performances, playlists, mixes, timing edits and preferences on your device. Source media remains yours. Local imports do not require a cloud account. You can remove local app data through the operating system; keep backups of audio and playlist edits you want to retain.
Optional private cloud library
An owner can sync a NAS library to private AWS storage and authorize paired devices to browse and download it. The service processes library files and song metadata, device-pairing identifiers and access credentials to deliver those downloads. Network identifiers and service error information may be processed to operate and troubleshoot the service. Pairing credentials are stored using the device’s secure credential storage. A TestFlight invitation does not itself grant access to another person’s private song library.
Microphone and speech
Director voice commands are optional. If enabled, the app requests microphone and speech-recognition permissions and uses available on-device English recognition. Microphone audio is not uploaded or saved by the app. Recognized command text may be shown locally while listening. Disable listening in Voice settings or revoke permissions in system settings at any time.
Diagnostics and feedback
Audio-route and device diagnostics may be stored locally for troubleshooting. Feedback you choose to send can contain the information and attachments you include. Apple may process crash and beta-testing diagnostics through TestFlight according to its own privacy policies and your device settings.
Third-party services and retention
AWS hosts an enabled private cloud library. Apple provides platform permissions and TestFlight distribution. We do not sell your audio or use microphone recordings for advertising. Cloud copies remain until the library owner removes them; removing the app from one device does not remove the owner’s cloud or NAS originals.
Contact and requests
For privacy questions, device authorization changes or cloud-data requests, contact [email protected]. If you use someone else’s private library, its owner controls that library’s files and authorized devices.
