Equilzer does not record audio, upload audio, send audio to a server, sell audio data, or allow humans to listen to your audio. Audio is routed through Chrome's Web Audio API and immediately played back to your selected output device.
On first install, Equilzer opens the public Install Worthy welcome hub hosted on GitHub Pages. Loading that page makes a normal website request to GitHub Pages. The hub contains no analytics or tracking scripts and does not receive audio or Equilzer settings. Substack is contacted only if you choose to open or subscribe to Install Worthy.

The use of information received from Chrome extension APIs adheres to the Chrome Web Store User Data Policy, including the Limited Use requirements.
Equilzer does not sell user data. Equilzer does not transfer user data to third parties. Equilzer does not use user data for advertising, creditworthiness, lending, or any purpose unrelated to local tab audio processing.
Equilzer does not use remote JavaScript or remote WebAssembly. The extension's HTML, CSS, JavaScript, and image assets are packaged with the extension.
