Opening your local workspace…

How it works.

  1. 01Open an ICS file. Add a new event or choose an existing event to edit or delete.
  2. 02Review your changes in the popup, then save them to this workspace.
  3. 03Download the updated calendar, or reset to the original file.

The important details.

The editor works on cloned calendar components, not a rebuilt agenda. Existing reminders, people, timezone definitions and custom fields are preserved unless their event is explicitly deleted. Deleting a recurring event removes its complete series after confirmation. The file on your device is never overwritten.

A good question.

Will edits update my calendar app automatically?

No. Save updates only this local workspace. Download the updated ICS file and import it yourself. Re-import behaviour is controlled by your calendar application.

Keep going.
