AirSynth does not collect or store your user data from the app on a server, or send to any third party.
Non-application data that AirSynth uses is orientated around user support, and application quality assurance. This is detailed below.
For users with the TrueDepth camera, AirSynth allows control of the synthesizer within the app. Depth data is processed as images (video frames), converted to a control value for pitch or volume. These depth images are not stored after use, persisted locally in the app, or sent to any third party.
Emails sent to AirSynth for support are processed via a service called ZenDesk.
Email support information is used only to provide support and respond to any software issues. Support emails are not used by AirSynth for marketing purposes.
AirSynth uses Apple App store analytics in order to record sales volumes, user opt-in analytics, and crash reporting information.
This information is provided via Apple's AppStore Connect service, and does not identify individual users.
