Privacy policy

Camera and depth

With your camera permission, AIRFIELD processes live front-camera images and available depth information on your iPhone to locate your hand, recognize gestures and measure movement. Images and raw depth data are processed in memory. The app does not record them, save them to files, upload them or include them in diagnostics. It does not identify you or use facial recognition.

Tracking begins when you start it or open a gesture or hand-range preview. Camera processing stops when the app becomes inactive. A preview can resume when you return, with MIDI control still off until you explicitly turn it on.

Phone motion

Optional phone-motion controls use device orientation, rotation and acceleration locally to generate MIDI values. They run only while enabled and the app is active. The app does not save or upload raw motion readings.

MIDI and Bluetooth

AIRFIELD sends musical commands, such as notes and parameter values derived from your movements, to the MIDI destination you select. That destination may be an instrument, another app or a computer, including a network MIDI destination provided by the operating system. The receiving device or software controls what happens to those commands; choose a destination you trust.

With Bluetooth permission, AIRFIELD advertises the generic name “AIRFIELD” while active, so nearby devices may see it. The advertisement does not contain your name, camera images, settings or hand data. Bluetooth MIDI connections and device discovery are managed by iOS. Nearby devices may also observe normal Bluetooth identifiers and connection information.

Settings and saved scenes

Mappings, calibration, sound labels and saved scenes are stored in the app’s private storage on your device. If a settings file cannot be used, AIRFIELD may keep a local recovery copy to protect your previous configuration. These files stay until you change or delete the relevant data or delete the app. Recovery copies remain until the app’s data is deleted.

AIRFIELD has no developer-operated cloud sync. iOS or computer backups may include these local files according to your backup settings, and restoring a backup may restore them.

Diagnostics you choose to share

The app keeps up to 200 recent MIDI trace entries in memory for troubleshooting. Export diagnostics creates a local text file with the app version, device model and iOS version, current settings and labels, camera and connection status, the selected MIDI destination name, timing statistics and that trace. It excludes camera images, raw depth maps and the saved-scene library.

Exporting does not send the file to the developer. You choose whether to save or share it using the iOS share sheet and who receives it. Review the file before sharing: custom labels and connected-device names may contain personal information. The temporary export may remain in the app’s temporary storage until replaced, cleared by iOS or removed when the app is deleted. Copies you save or send are controlled by you and their recipients.

Your choices and deletion

• Change camera, Bluetooth and motion permissions in iOS Settings. Features that need a disabled permission may be unavailable.
• Turn phone motion off in Setup. Turning Control off stops gesture-driven MIDI output; it can leave local hand tracking running for preview. Leave the app or revoke camera permission to stop camera processing.
• Delete saved scenes in Setup → Scenes. Deleting a scene leaves the current mappings unchanged.
• Use Delete App in iOS to remove AIRFIELD’s local settings, scenes, recovery files and temporary exports. Offloading the app keeps its data. Manage device backups and any exported copies separately.
• For information you have sent to the developer, request access, correction or deletion at the email address below.

AIRFIELD has no advertising or analytics SDKs, no account system and no in-app microphone recording.
