Sync events across multiple local device calendars automatically.

Calendar Sync automatically copies events from one local calendar to another on your device. When an event appears in your source calendar, a corresponding event is created in your target calendar using a name you choose.
Perfect for sharing availability across personal and work calendars, or keeping multiple calendars in sync without manual entry.
Features:
- Select any local device calendar as source or target
- Customize the synced event name (e.g., "Busy")
- Original event title is preserved in the description
- Sync runs automatically in the background at your chosen interval
- Changes to already-synced events are detected and propagated
- Deletions in the source calendar are mirrored to the target
No account required. All data stays on your device.
