Privacy policy
VIBRANIUM is a synthesizer and MIDI expander for Android published by Papazuzu Studio. This page explains what data the app uses. In short: the app requires no account, shows no ads, contains no analytics or tracking tools, and Papazuzu Studio receives no data about you.
Data stored on your device
Your sounds, banks, songs, settings and current session are saved only in the app's private storage on your phone or tablet. They are not sent anywhere. They are deleted if you uninstall the app or clear its data. Files you export (sounds, banks, songs) are saved where you choose, and only you decide whether to share them.
AI assistant (optional feature)
- Local AI: the model runs entirely on the device, without Internet. When you install it, the model file is downloaded once from Hugging Face (huggingface.co); as with any download, that service sees your IP address.
- Claude (Anthropic), OpenAI or Gemini (Google): only if you enter your own API key. Your request (the text you type or dictate) and a description of the current sound are then sent directly from your device to the provider you chose, over HTTPS, to get the answer. Papazuzu Studio sees neither these exchanges nor your key. This data is processed under the privacy policy of the provider you chose. Your key is encrypted on the device (Android Keystore) and you can delete it at any time.
- Voice dictation: it uses your device's speech recognition service (for example Google's). The app does not request microphone access and does not record your voice; only the recognized text is passed to it.
Purchases
The purchase of VIBRANIUM Premium is handled by Google Play. Papazuzu Studio does not receive your payment details; the app only checks with Google Play whether the purchase was made.
Permissions
- Bluetooth: find and connect Bluetooth MIDI keyboards. On Android 11 and earlier, the system requires the location permission for Bluetooth scanning; the app neither reads nor stores your location.
- Notifications and foreground service: show the notification that lets sound continue while the app is in the background (optional).
- Internet: only for the AI assistant described above and the download of the local model.
