betterXplayer stores unfinished-video progress locally in the browser using the extension storage API.
It does not:
- send playback history to a remote server
- sell or share personal data
- use analytics, ads, or trackers
- collect account credentials, messages, or contacts
Stored data is limited to what the extension needs to resume unfinished long-form videos on X:
- tweet URL
- tweet text snippet/title
- author display text
- poster image URL
- video duration
- last watched position
- local timestamps used for sorting and cleanup
All data stays on the device unless the browser itself syncs extension storage in a way the user has separately enabled.
