Managing multiple calendars is a pain. Work is on one, personal on another, side projects on a third — and none of them can see the others.
The people looking at one of your calendars can’t see that you’re busy on the others. So they book over you. Meetings land on your personal time. Your “free” slots aren’t actually free.
Here’s the solution: Calendar Sync.

Before

After Calendar Sync
Calendar Sync does exactly what it says: it keeps your calendars in sync, automatically. No suite of features you’ll never use — just the one job, done well.
- Block your busy time everywhere. Connect two calendars, make one rule, and Calendar Sync mirrors your events across as clean “busy” blocks — your private details never leak.
- Sync one way or both ways — and two-way actually works. Change an event on either calendar and the other follows, with no duplicates and no loops.
- Set it once. Calendar Sync runs quietly in the background and keeps everything current. You never touch it again.
- Your data stays yours. Self-hosted and encrypted. No one mines your schedule.
Bonus: Google Appointment Scheduling respects all your calendars — no extra setup
Sync your calendars, and Google’s Appointment Scheduling (the “book time with me” page) automatically sees the busy time from every one of them — not just your primary. People book only the slots you’re genuinely free.
