This Privacy Policy describes how Fader Flux ("the App") handles your data. The App is designed as a MIDI controller and virtual analog synthesizer and prioritizes user privacy by processing data locally on your device.
Audio and Microphone Data
Purpose: The App requests the RECORD_AUDIO permission to enable the Vocoder and Sing Notes (pitch tracking) features.
Processing: Audio captured via the microphone is processed in real-time using a transient, volatile ring buffer for digital signal processing (DSP).
Storage: The App does not record, store, or transmit your voice or any audio data to external servers. Once the audio is processed for synthesis or note recognition, it is immediately discarded from memory.
Bluetooth and Location Data
Purpose: The App requires Bluetooth permissions (BLUETOOTH_ADVERTISE, BLUETOOTH_CONNECT) to function as a BLE MIDI Peripheral.
Usage: These permissions are used strictly to discover and connect to MIDI-capable hosts (such as your PC or tablet) to send MIDI note and control data. We do not collect or track your physical location.
Network Information
Purpose: The App includes a TCP MIDI Bridge.
Usage: If you choose to use the TCP bridge, the App will transmit MIDI data over your local Wi-Fi network to an IP address and port specified by you. No personal information is transmitted over this connection.
Local Presets: The App uses SharedPreferences to save your custom MIDI mappings, routing preferences, and synth presets locally on your device.
External Access: This data is not synchronized with any cloud service and remains under your control on your hardware.
Third Parties: We do not share any personal information or processed audio data with third-party companies, advertisers, or analytics providers.
MIDI Data: The only data leaving the App is standard MIDI protocol information (Note On/Off, CC, Pitch Bend) sent via your chosen connection method (USB, BLE, or TCP).
Fader Flux does not knowingly collect any personally identifiable information. Since all audio processing is local and non-persistent, the App is safe for users of all ages.
