Features

• Pull-only ingestion of remotely hosted iCal and ICS links
• Incremental syncing on Google and Outlook using provider sync tokens rather than refetching everything
• Event content agnostic syncing engine
• Push aggregate events to one or more calendars
• Per-source privacy controls to strip event names, descriptions, and locations, replacing the title with a `{{calendarname}}` or `{{eventname}}` template
