One major goal of Lightning is to protect your privacy. Unlike many other launchers, Lightning has been designed without Internet access, as such it cannot share any private information with anyone. The app doesn’t collect personal data nor transmit them outside of your device.
Below is the exact list of permissions used by the app.
- Status bar and wallapaper
- Used by the lock screen to select a screen to display once unlocked (depends on Android versions)
- Backup & restore are stored on the external storage
- Direct dial shortcuts, you add them on the home screen, which then need this permission to initiate the call
- Needed by the app killer and the app drawer to list tasks
- Messaging related: query accounts for which to display unread counter, query messages and phone call logs for unread/miss items
- Tasker permission
- Play Store access to check the license and allow billing
Since Lightning Launcher can be greatly customized through scripting, you should check that plugins and themes you install come from trusted sources.
