Drumbridge is a companion app for Teenage Engineering EP-series sampling drum machines. This privacy policy describes what data the app handles and, more importantly, what it does not collect.
Drumbridge collects nothing. At all.
If you use Drumbridge offline on airplane mode, it will work exactly the same as with an internet connection — because the app never touches the network.
Drumbridge runs entirely on-device and communicates with your Teenage Engineering EP-series hardware over a physical USB-C MIDI connection.
Files created or read by the app are stored in one of two places:
Nothing is uploaded anywhere. The app has no servers. There are no servers.
Drumbridge requests the following iOS permissions only when you use the corresponding features:
| Permission | Why |
|---|---|
| Microphone | Only used if you tap Auto-Sampler to record audio from an external synth, or when the app plays back audio you import. Audio never leaves your device. |
| Files / Documents | To read sample files you pick and save exports/backups you create. |
Drumbridge does not request contacts, photos, location, health, calendar, reminders, camera, Bluetooth, or any other sensitive data.
To comply with Apple’s iOS 17+ privacy manifest requirements, Drumbridge declares the following uses of required-reason APIs in its PrivacyInfo.xcprivacy manifest:
C617.1: display to user).mach_absolute_time) — used by the project playback engine to schedule sample triggers with sample-accurate timing (reason code 35F9.1: measure time between events within the app).Neither API is used for tracking, fingerprinting, or any purpose other than the functionality described above.
Drumbridge has an age rating of 4+ and is safe for all ages. Because the app collects no data, nothing about a child (or anyone else) is ever recorded or transmitted.
If the app ever changes to collect data in the future, this policy will be updated and users will be notified via the app’s release notes. As of this version, that is not planned.
