storage keeps your books and settings on your device; sidePanel shows the live reading-session timer; commands registers the optional keyboard shortcuts. The single host permission (the Extension Factory site) is used only to fetch the Support-button display-config and sends no personal data.
Logging a reading session (or updating your current page) records the day, which builds your streak and fills the heatmap. Set a yearly goal by books or pages in Settings, and the Stats tab shows your progress ring for the year.
