Support & FAQ

No. NightToggle only changes your Windows theme preferences — the same two settings you'd change manually in Settings > Personalization > Colors. With presets, it can also set your wallpaper, accent color, and brightness. All changes are reversible in one click via Safety > Restore previous values.

The core toggle changes two registry values:

• AppsUseLightTheme — your apps theme preference
• SystemUsesLightTheme — your system theme preference (taskbar, Start menu)

With presets (optional), it can also change your desktop wallpaper, Windows accent color, and monitor brightness. You can see everything NightToggle touches by clicking Safety > What we change in the tray menu.

NightToggle switches Windows to dark mode, but some legacy Windows dialogs and older Win32 apps don't fully support dark mode. This is a Windows limitation, not a NightToggle bug. Most modern apps and the entire system UI (taskbar, Start menu, Settings) will switch correctly.

Yes. NightToggle is 100% local — no accounts, no telemetry, no analytics, no network calls. Your settings are stored on your machine and never transmitted anywhere. See our Privacy Policy for details.

Another app is likely overriding your theme. NightToggle has a built-in conflict detector — right-click the tray icon and go to Help > Theme keeps switching back. It will check for known conflicts like:

• PowerToys — the "Awake" or "Color Picker" modules can interfere
• Other theme-switching apps — if another app manages your theme on a schedule, it will override NightToggle's changes
• Windows Focus/Do Not Disturb — some configurations trigger theme changes

The conflict helper provides specific steps to resolve each detected issue.

Try these steps:

• Right-click the tray icon > Help > Refresh UI now — this broadcasts a settings-change signal to force Windows to update
• If that doesn't help, try Help > Restart Explorer — this restarts the Windows shell
• Check the Activity log (Help > Activity log) to see if the toggle registered
• Check for conflicts (Help > Theme keeps switching back)

Right-click the tray icon > Safety > Restore previous values. This restores the exact theme settings that were active before your last toggle. You can also choose Restore Windows defaults to reset to the Windows out-of-box theme settings. These safety tools are always free.

All settings are in %AppData%\NightToggle\:

• config.json — your preferences, schedule, presets
• activity.log — recent actions (last 50)
• wallpapers\ — cached wallpaper images for presets

If you uninstall via the Microsoft Store, these files are cleaned up automatically.

NightToggle Pro ($2.99, one-time) adds convenience features:

• Sunrise/sunset scheduling — auto-switches theme with the seasons
• Manual scheduling — set your own Light/Dark times and days
• Theme presets — bundle wallpaper, accent color, and brightness into one-click profiles
• Multi-display wallpaper — different wallpaper per monitor
• Preset hotkeys — instant switching between setups
• Monitor brightness control (Beta)

Safety and reliability features are always free. Pro is for convenience, not stability.

Make sure you're connected to the internet — NightToggle verifies your Pro purchase through the Microsoft Store on startup. If you recently purchased, try restarting the app. Your purchase is tied to your Microsoft account, so it will carry over if you reinstall.

NightToggle is toggle-first — one tray click, no settings window. It's also safety-first: see exactly what changes and undo in one click (free). Pro adds bundled theme presets with wallpaper, accent color, brightness, and multi-display support. NightToggle is for people who want a fast, transparent toggle-first experience.
