Vulcan

Vulcan

A home screen for Android that does what Nova does, with no internet access at all.

  • No internet permission
  • No ads or trackers
  • Android 8+
Vulcan's home screen: a large light clock and the date over a dusk wallpaper, four app icons in the dock

Built like an appliance, not a phone skin.

Warm-grey panels, small printed labels, and one orange dot for whatever is live. Your wallpaper and your apps' own icons are left alone. Every Nova-style option is still in settings when you want it.

Nothing it does can leave your phone.

Vulcan doesn't ask Android for internet access, so it has no way to send anything anywhere. There are no ads, analytics or crash reports. That's in the app's permission list, where anyone can check it.

Notifications are counted in memory and never saved.

Contact searchAsked when you turn it on

Find people from the app drawer, and favourite contacts on the Now page.

Screen lock gestureOff until you turn it on

Uses the last location your phone already knows. The sun times are worked out on the phone.

What Nova sends, and what Vulcan doesn't.

Nova Launcher changed owners in 2022 and again in January 2026, and picked up ads and trackers along the way. This is what the current version contains.

The Nova column comes from reading the code of the Nova Launcher 8.9.4 app (October 2026) without running it, so it shows what the app contains, not what it sent from any one phone. How this was checked.

Bring your Nova home screen with you.

Your apps, folders, dock, grid size and most shortcuts come over. Widgets have to be added again.

  1. In Nova, open Nova Settings → Backup & import settings → Backup and save the file.
  2. In Vulcan, long-press an empty spot, then tap Settings → Backup & restore → Import a launcher backup and pick that file.

Nova's depth, kept out of the way.

Sensible defaults out of the box. Everything else is in settings.
