Connect each email account
Connect the Google and Microsoft logins that hold your calendars. No calendar passwords are stored.
One calendar view for work and private life
Sync every calendar into the one you actually use.
Most people have calendars spread across different email accounts: work Outlook, private Google, client Microsoft 365, or side projects. Connect your calendars and choose what copies where. Events sync from each source calendar into the destination calendar you check every day.
We request Google Calendar list access and event access only to show your calendars, read the source calendar you choose, and create or update copied events in the destination calendar you select. See our Privacy Policy and Terms of Service.

The problem
Scheduling breaks when your life is split across calendars.
You check the wrong calendarA free slot in Outlook is not really free if your private Google calendar is already booked.
People book over your private timeAppointments outside your work calendar stay invisible to colleagues and clients.
Finding a slot takes too longYou switch between calendars, compare availability manually, and still risk double bookings.
The solution
Pick one destination calendar as your source of truth.
Choose the calendar you want to live in every day. Sync Calendars copies appointments from your other source calendars into that destination as private blockers, title-only events, or full copies.

How it works
Connect your calendars, pick a destination, decide what copies where.
Choose the destination calendar
Select the calendar you want to check every day. This is where copied events land.
Add your source calendars
Create rules that copy appointments from work, private, client, or side-project calendars into the destination.
Control privacy
Copy only busy blocks, copy titles with prefixes, or copy selected details when you need them.
Configuration
Everything you need to build one reliable calendar view.
Sync calendars into one destination
Copy events from Google, Outlook, Microsoft 365, client, and side-project calendars into one destination calendar.
Private blockers
Show that you are busy without exposing title, guests, body, location, or meeting links.
Smart filters
Skip free, tentative, declined, private, all-day, or category-tagged events.
Changed events stay aligned
When source meetings move or disappear, copied events can update, delete, stay, or become cancelled.
Prefixes and templates
Use names like Work: Client call, Personal: Busy, or keep every copied event simply named Busy.
OAuth, not passwords
Users connect through Google and Microsoft login screens. We do not ask for account passwords.
Privacy first
Your main calendar can show availability without revealing your life.
Busy onlyNo title, guests, body, location, or links.
Title onlyAdd a source prefix such as Private: Dentist or Client A: Review.
Custom detailsChoose title, description, location, participants, and Teams or Meet links separately.

FAQ
Common calendar merge questions.
Does Sync Calendars replace my calendar app?
No. It keeps your existing Google and Outlook calendars, then copies appointments into the destination calendar you check every day.
Can I sync Google Calendar with Outlook?
Yes. Connect the Google and Microsoft email accounts, choose the source calendar, choose the destination calendar, and pick what the copied events should show.
Can copied events hide meeting details?
Yes. Busy-only mode creates private blockers without title, attendees, location, description, or meeting links.
Do you need my Google or Microsoft password?
No. Users connect through Google and Microsoft OAuth. Sync Calendars stores access tokens, not account passwords.
Why do you need Google calendar access?
We use Google Calendar list access to show your available calendars and Google event access to read the source calendar you select and create or update copied events in the calendar you choose as the destination.
