Book one calendar.
The rest fold around it.
busyfold mirrors free/busy across all your Google calendars. Get booked on one and the slot blocks on every other — automatically, in the background.
Mirrors your busy time across every Google calendar you connect.
How it works
Set it once. Then forget it.
Connect your Google calendars, draw the links that should mirror each other, and busyfold keeps them in sync in the background — reacting the moment anything changes.
-
Connect your calendars
Sign in with Google and authorize each account you want in the loop. One grant covers reading busy time and writing blocks, so an account can be a source, a destination, or both.
-
Draw the connections
On a visual canvas, link a source calendar to the destinations that should mirror it. Connections are directional, so you decide exactly what shows up where.
-
Let it run
The instant an event lands, busyfold writes a private ‘unavailable’ block on every linked calendar — usually within seconds, and never with your event titles attached.
Updates happen the moment your calendar changes — no refresh, no waiting.
See it work
Busy in, blocked out.
Wire your calendars together on a canvas, and busyfold mirrors busy time across them. The details fold away — only your free/busy crosses over, just the way you like it.
Connect your calendars
Connect a source calendar to the destinations that should mirror it. Each calendar's role — source, destination, or both — follows the connections you draw.
Mix work and personal, fan one calendar out to many — wire them however your week actually works.
How your events appear
Same times, same shape — every title, guest, and note stays home.

What everyone else sees
No titles, no guests, no locations — just an honest unavailable.
Tune it to your liking
A few quiet settings decide how those blocks look and when they land.
Features
Everything it does, quietly.
Powerful where it counts, invisible the rest of the time.
-
Privacy by design
Only free/busy time crosses over. Titles, guests, notes, and locations never leave the source calendar.
-
Near-instant sync
Google push notifications trigger updates the moment your calendar changes; scheduled sweeps catch anything missed.
-
Never double-booked
Conflict-aware merging skips real events and your own manual blocks, and updates existing blocks instead of piling up duplicates.
-
Tidy by default
Adjacent busy periods within your gap threshold merge into one clean block, so calendars stay readable.
-
Your window, your rules
Sync as far ahead as you like — anywhere from a single day to a full year.
-
Weekends off
Optionally leave Saturdays and Sundays untouched, evaluated in your own timezone.
-
Make it yours
Pick the title and colour busyfold paints on destination calendars.
-
Across all your calendars
Connect as many Google calendars as you like and choose exactly which ones mirror each other.
Privacy by design
Your calendar’s contents never leave home.
busyfold mirrors when you are busy — never what you are busy with.
Crosses over
- The start and end time of each busy period
- A single ‘unavailable’ marker on the destination
A frosted, generic block on the destination. No one can tell what it is — only that the time is taken.
Never leaves the source
- Event titles
- Guests & attendees
- Descriptions & notes
- Locations
- Attachments & links
- Video-call details
busyfold never reads, copies, or transmits any of it.
FAQ
Questions, folded out.
The short answers on privacy, syncing, and control — before you connect a single calendar.
Does busyfold see my event details?
No. It reads only your free/busy time. Event titles, guests, descriptions, and locations are never read into blocks or stored anywhere.
Will it double-book me or clutter my calendar?
No. busyfold won't write over real events or your own manual blocks, it merges nearby busy periods, and it reuses its own blocks instead of creating duplicates.
How fast does it sync?
Almost instantly — the moment your calendar changes, the blocks update.
Which calendars can I connect?
Any Google calendars you authorize. Each account grants access directly, and a single account can act as both a source and a destination.
Does it work with more than one Google account?
Yes. Connect as many calendars as you like — any account can mirror to or from any other.
Can I customise the blocks it creates?
Yes — choose the title and colour busyfold paints on destination calendars, set how far ahead it syncs, merge nearby blocks, and optionally skip weekends.
Stop refereeing your calendars.
