Using lumabar

Install and activate

1. Choose Buy on this site and pick your Windows version. If you are not sure, it is 64-bit.
2. Pay on Polar's checkout. The installer and your license key arrive by email, and both stay available from your Polar receipt.
3. Run the installer. lumabar starts on its own and docks to the bottom of the screen.
4. Paste your license key and press Activate. Activation only happens when you press the button - lumabar never reads your clipboard.

One key activates one PC. Reinstalling on the same PC reactivates it with the same key.

Add, remove and arrange widgets

1. Right-click the dock and choose Widgets… to open the widget picker.
2. Browse by category or search, then click a tile to add it to the dock.
3. Click the tile again in the picker, or the − badge on the dock while the picker is open, to remove it.
4. Drag any widget along the dock to change the order.

Move the dock to the top of the screen

Drag the dock by an empty spot and release it in the top half of the screen: it snaps to the top edge, and its panels open downward. Drag it back down to return it to the bottom. lumabar remembers the edge.

Styles, size and clock

• Settings → Appearance: Black, White, Liquid Glass, iOS Glass or Midnight.
• Settings → Dock → Size: S, M or L.
• Settings → Dock → Clock: 12-hour or 24-hour.
• Settings → Launch at startup: start lumabar with Windows.

The Windows taskbar

While the dock is open, lumabar sets the Windows taskbar to Auto-hide (it slides up when your pointer reaches the screen edge) or Hidden - your choice in Settings. lumabar does not modify Windows files: quit lumabar and the taskbar is back the way it was.

The Windows key and the Start tile in the Apps widget still open Start. When a game or video goes fullscreen, the dock hides itself and comes back when you leave fullscreen.

Connect accounts

Widgets that read an online account - revenue, analytics, social, mail, GitHub and some AI tiles - show a sample until you connect them. Click the tile and its card explains what it needs: usually a read-only key that you create in that service's dashboard.

Stripe needs a restricted key (rk_live_…) with read access to Balance transactions. Polar needs an organisation access token that can read metrics. Keys are stored only on your PC.

Updates

lumabar checks for a new version a minute after it starts and every few hours after that. When one is out, the dock offers an Update button: one click downloads and installs it, and lumabar restarts. Settings shows the current version and checks again whenever you open it.

Updates are free for every license.

Uninstall

Open Windows Settings → Apps → Installed apps, find lumabar, and choose Uninstall. The Windows taskbar returns to normal immediately.

Help and feedback

Something not working, or a widget you want? Use Feedback in the dock's Settings, or message lumabar on X.

Security and privacy

lumabar has no account, no server of its own and no telemetry. Every widget talks straight from your PC to the one service it shows - nothing passes through us.

Keys you paste are kept as plain files in lumabar's folder under your user profile (%APPDATA%\com.lumabar.dock), readable by your Windows account - which is why read-only keys are the safe choice.
