One of NimbleCal's core strengths is working reliably when you're offline. Whether you're on a flight, in a tunnel, or somewhere without service, your calendar stays usable.
What you can do offline
Everything you need for viewing your calendar works offline:
- View all your calendars and events that are already synced to this device
- Search and browse your existing data
- Navigate between views (day, week, month, agenda)
- Check event details including notes, locations, and reminders
Your data is stored locally, so it's always available—no internet required.
Editing while offline
Making changes to your calendar while offline (creating, editing, or deleting events) is a Plus feature.
Why Plus only?
Offline edits require sync infrastructure to merge your changes when you reconnect. This ensures your edits don't conflict with changes from other devices and keeps everything in sync.
If you're offline on the Free plan, NimbleCal will continue working for viewing, but will ask you to go online if you try to make changes.

What happens when you reconnect
When you come back online:
- With Plus: NimbleCal syncs your offline edits across your devices
- On the Free plan: offline edits are blocked, so there is nothing new to sync
The sync happens in the background—you don't need to do anything. Just keep using your calendar normally.
Pro tip
If sync runs into trouble, NimbleCal will show a small "Sync issue" banner so you know it needs attention.
