How to share calendar availability without event details

The safest availability link answers one question: when can we meet? It does not need to reveal what your existing meetings are called, where they happen, or who attends.

What is the difference between free/busy and event details?

Free/busy data describes time ranges that should be treated as occupied. Google Calendar’s FreeBusy query returns busy ranges with a start and end, while Microsoft Graph’s getSchedule API returns free/busy availability for a requested period. Neither description requires publishing an event title to the person choosing a time. Google Calendar FreeBusy documentation and Microsoft Graph getSchedule documentation, fetched October 7, 2026.

How can I share availability without sharing my calendar?

Use a link that exposes only open times and keeps the underlying calendar private. OpenCal reads busy times from the calendars you connect, shows visitors your available times, and says in its privacy policy that links show free time rather than busy blocks, titles, places, or guests. The OpenCal privacy policy, fetched October 7, 2026, describes the fields read and stored.

How does OpenCal combine several calendars?

OpenCal treats each selected calendar as busy when it contains an occupied time, then presents the remaining time within your configured hours. That is useful when work, personal, or other calendars must all count before a slot is offered. OpenCal’s landing page and privacy policy say that the service can use connected Google, Microsoft, and iCloud calendars and that visitors see free time rather than event details.

What should I check before publishing an availability link?

Check three things: the calendars that count as busy, the hours and time zone you want to offer, and whether booking should add an event to a connected calendar. OpenCal’s settings control these choices; its privacy policy explains that bookings and connected-account data are separate from the free/busy view. Review the public link in a private window before sending it, and remove any calendar you do not want to affect availability.

Can a recruiter or client book without seeing my meetings?

Yes, when the link is configured to show availability rather than event data. OpenCal’s public view is designed for a person to choose an open time, while the existing event titles, places, and guests remain in the owner’s calendars. If you need a two-person view, OpenCal also describes comparing both people’s availability and returning only shared free times in its privacy policy, fetched October 7, 2026.
