TabGroupie does not collect, store, or transmit any user data.
All preferences (collapsed group state, "hide pinned tabs" toggle) are stored
locally in your browser's localStorage and never leave your device.
No analytics, no tracking, no telemetry, no remote requests.

The "tabs" permission is used only to read tab metadata (title, URL, favicon)
for grouping; "tabGroups" is used to create and manage groups; "activeTab"
is used to switch focus when you click a tab in the popup.
