MIDI Recorder — Privacy Policy

Last updated: 2026-04-21

Summary: MIDI Recorder is an offline app. It does not collect, transmit, or share any personal data. The app does not hold the Android INTERNET permission, which means it technically cannot send any data off your device.

What the app stores on your device

Everything the app keeps lives on your device and is removed when you uninstall it. Specifically:

Your MIDI recordings (.mid files) — saved into a folder you choose through the system file picker. The app only reads and writes inside that folder.
Your settings (tempo, metronome options, auto-connect preferences, etc.) — stored in the app's private SharedPreferences.
Paired device info — the Bluetooth / USB identity of keyboards you have connected, so the app can auto-reconnect. Kept locally only.
In-app purchase state (see below) — a single flag indicating whether the "Full Version" unlock has been purchased. No payment details are stored.

Permissions and why the app asks for them

Every permission is used strictly for the feature it belongs to. The app does not use any of them for advertising, analytics, or profiling.

Permission	Purpose
`BLUETOOTH_CONNECT`, `BLUETOOTH_SCAN`	Required to discover and connect to BLE (Bluetooth Low Energy) MIDI keyboards. `BLUETOOTH_SCAN` is declared with the `neverForLocation` flag, so the app does not request any location permission and does not derive your physical location from Bluetooth scan results.
`FOREGROUND_SERVICE`, `WAKE_LOCK`, `POST_NOTIFICATIONS`	Keeps recording and playback running with the screen off, and shows the status notification while a session is active.
Companion Device permissions (`REQUEST_COMPANION_*`)	Enable auto-reconnect when your keyboard powers on. The device pairing is stored on your device by Android itself.

Google Play Billing

The app offers a one-time in-app purchase ("Full Version" unlock). The transaction is handled by Google Play under Google's Privacy Policy; the app never sees your payment details and only stores a local flag that the purchase exists. No other third-party SDKs are used — no analytics, no crash reporting, no ads.

Changes to this policy

If this policy changes, the updated version will appear on this page, and the "Last updated" date at the top will reflect the change. Material changes will also be noted in the app's release notes on Google Play.
