From a technical perspective: The app stores your recordings in iCloud by default, but this can be disabled. The app can function entirely offline, and will do so, if iCloud is turned off. From a legal perspective: On this issue, the 'music notes' license agreement just points you to the iCloud terms and conditions. And within the iCloud terms, you get this: > Apple does not claim ownership of the materials and/or Content you submit or make available on the Service. However, by submitting or posting such Content on areas of the Service that are accessible by the public or other users with whom you consent to share such Content, you grant Apple a worldwide, royalty-free, non-exclusive license to use, distribute, reproduce, modify, adapt, publish, translate, publicly perform and publicly display such Content on the Service solely for the purpose for which such Content was submitted or made available, without any compensation or obligation to you. As far as I can tell, you cannot make your recordings available to others within Music Notes itself, so the first sentence is the most relevant one. However, if you 'push' the recording into iCloud Drive or Garageband & share it from there, the other part would apply. Even then, the rights Apple claims are only slightly more general that what they'd need -- and since its 'solely for the purpose for which [it] was submitted', they'd have no claim to use them in their ads.
