Privacy Policy — PocketMIDI

Last updated: March 2026

PocketMIDI is a free, offline MIDI synthesizer for Android developed by JDevStudio. This privacy policy explains what information the app does and does not collect.

Data Collection

PocketMIDI does not collect, store, or transmit any personal data. The app operates entirely on-device and requires no internet connection.

Permissions Used

USB Host

Used to communicate with USB MIDI keyboards connected via OTG adapter. No data from the MIDI device is stored or transmitted.

Audio

The audio permission is declared in the manifest because the Oboe audio library requires it to access low-latency audio output on some devices. PocketMIDI does not record, process, or store any audio from the microphone.

Local Storage

PocketMIDI stores the following data locally on your device only:

• App settings (selected instrument, master volume, BPM, time signature)
• Named presets you choose to save

This data never leaves your device unless you explicitly use the preset export feature to share a file via another app you choose.

Third-Party Services

PocketMIDI does not use any third-party analytics, advertising, or crash-reporting SDKs. There are no trackers of any kind in the app.

Children

PocketMIDI does not knowingly collect any information from anyone, including children under the age of 13.
