Video details: optional. A free YouTube API key fills in details (like length) for links you save without opening them. "How to get a key" explains it, in five minutes. The key is kept encrypted on this computer, shown only as its first and last few characters, and never put in a backup or an export: Replace or Remove it any time.
Comfort: Inbox reminder, larger text, reduce motion, stronger folder colour, and the theme (follow YouTube, dark or light).
Your Matinee: monthly counts of what you've used, kept on this computer only. Copy summary if you want to share them.
Export: your whole library as Markdown or CSV, in the layout you choose (see below).
Help & feedback: opens our short feedback form in a new tab. Email us opens an email instead, with only the version number filled in. User guide opens this guide on Matinee's website.
If your Chrome is too old for something, Settings says what and how to update.
