Auditory Companion — Privacy Policy

Last Updated: 2026-04-15

1. Overview
#

Auditory Companion, developed by QQder339, is a sophisticated audio engine combining real-time DSP noise synthesis, 108 ambient sound samples, and AI-powered text-to-speech reading.

In short: We do NOT collect, store, or transmit any of your personal data to external servers.

2. Data We Do NOT Collect
#

This app does not collect:

  • Personally Identifiable Information (name, email, phone number)
  • Location data
  • Device identifiers
  • Usage analytics or tracking data

3. Locally Stored Data
#

The following data is stored strictly on your device and never transmitted externally:

  • Soundscape Settings: Your saved mixing configurations and favorite scenes
  • Reading Content: Articles, clipboard text, and other reading materials (processed locally only)
  • User Settings: Volume levels, sound preferences, auto-ducking settings, etc.

4. On-Device AI Features
#

Text-to-Speech (TTS) and audio processing run on-device:

  • AI Voice Reading: Uses iOS built-in TTS, or an optional downloadable MeloTTS on-device model; all speech synthesis runs on-device
  • Auto-Ducking: DSP signal processing runs entirely locally, analyzing voice and background audio in real-time to automatically adjust volume

5. Third-Party Services
#

This app does NOT use any third-party analytics or advertising frameworks (No Google Analytics, No Facebook SDK, No Ads).

6. Network Access
#

Core features (noise synthesis, scene mixing, iOS built-in TTS reading) operate fully offline. Network access occurs only when you explicitly trigger it:

  • Downloading the MeloTTS model (Optional): When you choose to download the on-device TTS model in Settings, the app fetches the model files from a public source and caches them locally
  • External Links: Opens the system browser when tapping relevant links

These requests transmit only the URL of the file you chose to download; no personally identifiable information is attached.
