Privacy Policy for Hotkey Audio Switcher

Hotkey Audio Switcher ("the App", "we", "us", or "our") is developed with privacy as a fundamental principle. This Privacy Policy explains our practices regarding user information.

1. Zero Data Collection

Hotkey Audio Switcher operates 100% locally on your device:

• No Personal Information: We do not collect, store, track, or share any personally identifiable information (such as your name, email address, IP address, or device identifiers).
• No Audio Recording or Monitoring: The App interacts with native macOS CoreAudio APIs solely to list available output devices and change the default output device upon your request. It never listens to, records, captures, processes, or transmits any audio content or microphone input.
• No Analytics or Telemetry: The App does not contain any third-party analytics libraries, advertising frameworks, tracking scripts, or telemetry services.
• No Remote Servers: The App does not communicate with external servers or transmit data over the internet.

2. Local Data Storage

Any preferences you configure within the App (such as custom keyboard shortcuts) are saved exclusively on your local Mac using standard macOS UserDefaults. This data never leaves your device.

3. macOS App Sandbox & Security

Hotkey Audio Switcher is built in full compliance with Apple's macOS App Sandbox guidelines. The App only requests the minimum system permissions necessary to perform its core function of switching audio output devices and registering global hotkeys.

4. Children's Privacy

Because the App does not collect any personal data whatsoever, it is fully compliant with the Children’s Online Privacy Protection Act (COPPA), GDPR, and other global privacy regulations regarding children under the age of 13 (or applicable age in your jurisdiction).

5. Third-Party Links

The App may contain links to our website (e.g., https://guokai.dev/audio-switcher/) for support or documentation. If you visit any external links, please note that those external websites have their own privacy policies.
