Nocturne Player collects nothing.

No personal data, no usage data, no crash reports, no identifiers, no analytics.

The extension has no network access whatsoever. There is no fetch, no
XMLHttpRequest, no sendBeacon, no WebSocket and no remote URL anywhere in its
source code, and an automated check rejects any change that introduces one.

What is stored: your settings — night light, colour adjustments, dim level,
subtitle size, playback speed, and the sites you disabled the player on. These
are written with the WebExtension storage.local API and stay on your device.
The extension deliberately does not use storage.sync, which would copy settings
through a Mozilla account. Uninstalling removes everything it stored.

Permissions:
- storage — remember your settings between sessions, on your device.
- activeTab — let the popup show which site you are on, so you can turn the
player off for that site. Granted only while the popup is open.

The content script matches all sites because it has to notice a video element on
whatever page you open. It reads only the video element and its subtitle tracks.
It does not read page content, form fields, cookies or history, and it has no way
to send anything anywhere.
