Google Calendar Sharing Permissions Explained in 2025

Google Calendar sharing permissions control who can see your events and what they can do with them. You set these permissions when you share a calendar, choosing from four levels: See only free/busy (hides event details), See all event details (view-only), Make changes to events (edit existing entries), and Make changes and manage sharing (full admin control).
When you juggle multiple work calendars (say, one for your main employer and another for freelance clients) sharing permissions become critical. Setting the wrong level can expose private appointments or let someone accidentally delete a recurring meeting. We built Calsync to handle exactly this: it syncs events across your Google Workspace accounts every five minutes while respecting the privacy level you choose, so colleagues see your availability without seeing whose meeting it is.
How Do I Change Sharing Permissions for My Google Calendar?
Open Google Calendar on a desktop browser (the mobile app limits permission settings). In the left sidebar, hover over the calendar name and click the three-dot menu. Select Settings and sharing. Scroll to Share with specific people or groups and click Add people. Enter the recipient's email, then click the permission dropdown to choose your level. Click Send to apply.
To edit existing permissions, return to that same Settings and sharing screen. Under Share with specific people or groups, you'll see everyone who already has access. Click the permission dropdown next to a name to upgrade or downgrade their level, or click the X to revoke access entirely. Changes take effect immediately, no confirmation email required.
If you manage separate calendars for different clients, you can sync two different Google Calendars while keeping permission boundaries intact. Each calendar retains its own sharing rules, so your personal events stay private even when work events copy over.
What's the Difference Between "See All Event Details" and "Make Changes to Events"?
With See all event details, recipients see titles, times, locations, descriptions, and attendee lists—but cannot edit anything or add new events. Use this when you want teammates to know your schedule without risking accidental changes (project managers checking contractor availability, or admins coordinating executive calendars).
Make changes to events grants edit rights. Recipients can modify or delete any event on the calendar, including ones they didn't create. They *cannot* change who else has access (that requires the fourth permission level, Make changes and manage sharing). Reserve edit access for close collaborators: an executive assistant managing your bookings, a co-founder coordinating team meetings, or a business partner who needs to reschedule shared deadlines.
When you sync calendars automatically, permission mismatches can cause confusion. If Calendar A is shared view-only but you need to edit events from Calendar B, the one-way sync breaks. CalSync handles this by copying events as new entries in the destination calendar. You control permissions independently on each side. Start your free trial and configure permissions in 90 seconds.
Can I Make My Google Calendar Public?
In Settings and sharing, toggle on Make available to public. You'll choose between See only free/busy (blocks of time with no titles) and See all event details (full transparency). Google generates a public URL anyone can view without signing in, useful for office hours or event schedules.
Public calendars carry risk. "See all event details" exposes every title, location, and attendee, so a leaked link reveals private appointments. Search engines can index public calendar URLs, making your schedule discoverable via Google Search. If you must go public, create a separate calendar for public events and leave your main calendar private. Learn how to make your Google calendar private by default to avoid accidental exposure.
For selective sharing, skip the public toggle and use Share with specific people instead. You maintain a guest list, and recipients need a Google account to view. If someone leaves your team, revoke their access immediately (they lose calendar visibility the moment you click the X).
What Do I Do When Someone Can't See My Shared Calendar?
Confirm you typed their email correctly, since entering a work address when they use Gmail (or vice versa) means the invitation never arrives. Check Share with specific people or groups in your calendar settings. If the address is wrong, delete it and re-add the correct one. Then ask them to look in their "Other calendars" list in Google Calendar's left sidebar, since shared calendars don't auto-appear in the main calendar grid. They click the shared calendar's checkbox to display events. If it's missing entirely, have them check their email for the sharing invitation and click Add this calendar.
Permission-level confusion causes phantom access issues. With See only free/busy, they see time blocks without titles. This is the expected behavior, not a sign of misconfiguration. Upgrade them to See all event details and ask them to refresh.
For syncing across accounts (like a personal Gmail and a work Workspace) Google treats these as separate identities. You can't share a Workspace calendar to a consumer Gmail account if your admin disabled external sharing. CalSync copies events between your accounts without needing admin permission—solving cross-account visibility without manual duplication.
FAQ
Can I share a Google Calendar without giving edit access? Yes. Choose See all event details when you add someone. They'll see every event but can't change anything. If you only want them to see when you're busy, pick See only free/busy instead.
How do I stop someone from seeing my Google Calendar? In Settings and sharing for that calendar, locate the person under Share with specific people or groups and click the X next to their name. They lose access immediately.
What does "Make changes and manage sharing" let someone do? They get full admin rights: add/edit/delete events *and* invite or remove other people from the share list. Only grant this to someone you trust completely, like a co-owner.
Can someone I share my calendar with see who else has access? No. Sharing permissions are private. A recipient sees your events but not the list of other people you've shared with, unless you give them Make changes and manage sharing.
Why do my shared events disappear when I change permissions? When you switch someone to See only free/busy, they stop seeing titles and descriptions. They still see time blocks. Revoking access entirely removes all events from their view. The events remain on your calendar.
Multiple Calendars? Use Sync to Eliminate Double-Booking
Sharing permissions solve access, but they don't solve double-booking when you run multiple Google Workspace accounts. You can share Calendar A to a colleague and Calendar B to a client, but *you* still see two separate grids and have to remember which one holds which meeting.
CalSync automatically merges all your Google Workspace calendars into one unified view. Set it up in under 2 minutes. You choose between full event details or busy-only blocking.
