Privacy Policy
Last updated: June 17, 2026
Treadle (“the app”) is a MIDI expression controller for iPhone. Your privacy matters, and the app is built to need none of your data.
Data we collect
None. Treadle does not collect, store, transmit, or share any personal information. There are no accounts, no analytics, no advertising, and no tracking of any kind.
Bluetooth
Treadle requests Bluetooth access for one purpose only: to send and receive MIDI messages to and from your music devices (synths, pedals, computers). Bluetooth is never used to collect data about you or your location, and nothing is transmitted off your device.
Network
The app makes no network requests. All settings are stored locally on your device.
Children
Treadle does not collect data from anyone, including children under 13.
Changes
If this policy changes, the updated version will be posted on this page with a new date.
