Every calendar you have, in one place.

One calendar. Delete something once and it stays gone.

Clearstream copies events from all of your Google calendars, including shared ones you can't edit, into a single calendar. Remove an event you don't need and it won't come back.

How it works
1

Connect

Add one or more Google accounts and pick up to 20 calendars, including ones shared with you read-only.

2

Combine

Clearstream creates a new calendar for the copies, or writes them into one you already have.

3

Tidy

Delete anything you don't want in Google Calendar. It stays deleted, even when the original changes.

Never sends invitations

Never touches your other events

Never writes to the calendars you copy from
