Google Calendar · one-way
Mirror availability as Busy. Details stay private.
Point a source calendar at a target. CalSync writes private Busy blocks and leaves titles, descriptions, attendees, and locations where they belong.
How it works
Pick source and target
Refresh calendars, then create a one-way sync. The target only receives Busy.
Busy blocks appear
CalSync mirrors the last 6 hours and the next 30 days. Changes usually land within a minute.
Trust
We do not copy event titles, descriptions, attendees, or locations onto the target. Mirrored events are private Busy blocks with a hidden ownership marker. Read the privacy policy.
Limits
- Google Calendar only. No Outlook.
- One-way availability. No two-way sync.
- No billing, teams, or shared-calendar rules yet.
FAQ
What details leave the source calendar?
Only busy/free times inside the sync window. Titles and other event fields stay on the source.
How far back and ahead do you sync?
CalSync mirrors the last 6 hours and the next 30 days. Events outside that window are left alone.
Can I use Outlook or make this two-way?
Not in this version. The product is Google-only and one-way on purpose.
How do I stop?
Delete a sync to remove the Busy blocks we created, or disconnect a Google account to revoke tokens and delete stored calendars for that account.
