Permissions & why
Save your preferences and results in Chrome's local storage on your device.
Access the tab you explicitly activate the extension on — only on your click, never in the background.
Inject the extension's feature logic into the active page, only when triggered by you.
Read the active tab's URL/title so the extension can show context and enable the right UI state.
Your data stays yours
AutoDark runs entirely locally in your browser. No data ever leaves your device. No analytics, no tracking, no telemetry. All settings and results stay in Chrome's local storage on your machine.
