## CalDAV synchronization

### What is CalDAV?

CalDAV is an Internet standard that allows applications like Fantastical to access calendar/scheduling information on a remote server. Many popular services including iCloud, MobileMe, and Google Calendar use CalDAV to synchronize your calendars.

Fantastical includes CalDAV support, which means you can add, edit, and view events on your server even when iCal isn't open.

### Setting up CalDAV in iCal

Please refer to iCal's documentation for help setting your CalDAV account. iCal provides quick setup options for iCloud, MobileMe, Google, and Yahoo! accounts. If you use a different CalDAV service you will need to enter your server's settings manually.

If you are using an application other than iCal, please refer to that application's documentation for more information on using it with CalDAV.

### Adding and editing events

Events you create or edit in a CalDAV calendar with Fantastical will automatically sync to the server, even if iCal isn't open.

### Viewing changed events on the server

If iCal isn't open, Fantastical automatically syncs your events with the server. However, if iCal is open, iCal handles the sync. In this case, iCal's refresh sync setting will determine how often events are synced with the server. Fantastical automatically syncs approximately every five minutes, so changes made on another device may take a few minutes to appear.

### Requesting Keychain Access

Fantastical uses your keychain to access your account and password information for your CalDAV account. If you see a dialog requesting access, please click "Always Allow". Otherwise, you will have to click "Allow" every time this dialog appears to allow Fantastical to access your account and password information. Your password will remain secure in the keychain.
