NimbleCal
Last reviewed Apr 9, 2026

Small preferences make a big difference in how your calendar feels day to day.

Open Settings

In the app, open Settings.

Keyboard shortcut:

  • Mac: Cmd + ,
  • Windows/Linux: Ctrl + ,

Timezone

Set your timezone so event times display correctly (especially if you travel).

If something looks an hour off, check this first.

Search works with city names, IANA zone names, and UTC / GMT.

Week start day

Choose whether your week starts on Sunday, Monday, or Saturday.

This affects the Week and Month views.

Theme

Pick a theme that feels good:

  • System
  • Light
  • Dark

Keyboard shortcuts (handy when you're presenting):

  • System: Shift + S
  • Light: Shift + L
  • Dark: Shift + D

Notifications

Reminders use browser notifications. In Settings, you can:

  • Enable notifications
  • Send a test notification

See: Reminders and notifications

Grid contrast

This is an accessibility setting. If the calendar grid lines feel too faint (or too strong), try Grid contrast:

  • Subtle
  • Standard
  • High contrast

On touch-first devices, NimbleCal automatically keeps the desktop hover crosshair out of the way, so this setting mostly affects the always-visible grid scaffold there.

Maps provider

When you click a location that is not a URL, NimbleCal can open it in:

  • OpenStreetMap (default)
  • Apple Maps
  • Google Maps

Quick unlock

If you use a trusted device, you can set up Quick unlock so you can unlock with your face, fingerprint, or device PIN after restarts. It helps only on that device. A brand-new device still needs your NimbleCal password before it can unlock your encrypted data.

If your browser supports it, NimbleCal can also remind you right after a password unlock so you can set it up without hunting through Settings.

Stored on this device only
When you set it up, NimbleCal stores a protected copy of your encryption key on that device only. It does not unlock your account on a different device.
Only on devices you trust
If someone else can unlock your device (biometric/PIN), they could unlock NimbleCal too.

Crash reports

If Crash reports are available in your build, the app can send a small report when NimbleCal crashes or fails to start.

Crash reports are on by default when available, and you can turn them off in Settings at any time.

What those reports include:

  • Build version
  • A general route area like /calendar or /settings (/other for everything else)
  • General browser and operating-system family
  • Online/offline state
  • Error details

What they do not include:

  • Event titles, descriptions, notes, or locations
  • Email addresses
  • Invite links
  • Account IDs
  • Product analytics or session replay

This setting applies to the current browser only.
