YouTube Miniplayer does not collect, transmit, or share any personal data.

What is stored: Your settings (player size, position, opacity, etc.) and the
enabled/disabled state are saved locally in your browser using the WebExtension
storage API. This data never leaves your device.

YouTube iframes: When you open a YouTube link, the video loads in an embedded
YouTube iframe directly from YouTube's servers. This is subject to YouTube's own
Privacy Policy (https://policies.google.com/privacy). The extension does not
intercept or store any data from these requests.

No analytics, no tracking, no external servers. The extension operates entirely
on your device and makes no network requests of its own.
