RackDroid is a modular synthesizer that runs entirely on your device.

No data collection

RackDroid does not collect, store, or transmit any personal data, usage analytics, or telemetry.

No network access

The app performs no network requests. Patches, audio recordings, and settings are stored only in the app's private storage and, when you explicitly export them, in your device's Documents/RackDroid/ folder.

Microphone

The RECORD_AUDIO permission is used exclusively to route live audio input into the synthesizer's AUDIO module (e.g. to process an external instrument). Audio is processed in real time on the device and is never transmitted. You can deny this permission; the app then runs output-only.

Bluetooth

Bluetooth permissions are used exclusively to connect Bluetooth LE MIDI keyboards and controllers you choose from the in-app scanner.

Notifications

The notification permission is used only for the foreground-service notification that keeps audio running in the background.

No accounts, no ads, no third-party SDKs

RackDroid has no user accounts, shows no advertising, and embeds no third-party analytics or advertising SDKs.
