Works with the Google and Microsoft calendars you already use. Nothing to replace.
The problem
Two calendars. Zero communication.
Work books over the appointments that matter because it cannot see them.
So you cope. Badly.
The decoy blocks
You copy events onto every other calendar by hand. Then plans change, and you maintain the copies too.
The overshare
You put the pediatrician on the work calendar so the time is safe. Now it lives on your employer's server.
The tab check
You open every calendar before you say yes to anything. You still miss one.

I thought the recital was next week.I already told the client Thursday works.Which calendar was that on.
The double booking is never with the meeting. It is always with your life.
How mirroring works
We mirror Busy. Not your business.
Busy
No title.
No attendees.
No location.
Kaiju reads the original event details on its own servers to build the placeholder. That is the only place the title, the attendees, and the location are ever seen. Then it writes one block onto every other calendar. Only the word Busy travels. Nothing else leaves the calendar it was booked on.

Not a statistic. Just arithmetic.
Who it's for
Your calendars already know the problem.
Four lives, one mechanic. The time blocks itself in the calendars you already have.
Work and personal
The personal event was on your personal calendar. The 4pm sync landed right on top of it, because work cannot see your life. The meeting won. The apology was yours.
Now the personal event blocks your work calendar the moment it exists, labeled only Busy. Work knows you are gone. It never knows where.
The block lands in the same work calendar your job already runs on. Nothing new to check.
Side project builders
You are building something your employer does not know about yet. The investor call cannot say investor call on the work calendar. The slot cannot sit open either. So you guard it by hand and hope.
Kaiju guards the time and keeps the secret. The side project mirrors Busy onto work automatically. The meeting is protected. What you are building stays yours.
Colleagues book against the same work calendar they always have. It just says Busy now.
Freelancers
You quoted Thursday to a client from memory. The dentist was on the other calendar. Now you are writing the reschedule message and deciding which one of them hears it.
Every account blocks itself the moment anything books anywhere. Your availability stops lying.
Clients keep booking against the same business calendar as always. It just tells the truth about your time.
Fractional execs and agency owners
Company A pays for your Tuesdays. Company B just booked one of them. And neither of them is allowed to see the other's calendar to know.
Every company sees Busy and nothing else. Cross company discretion, enforced automatically.
Each company's own calendar stays untouched and IT approved. Kaiju only writes Busy blocks into it.
Keep your calendars. All of them.
How it works
Three steps. Then never again.
01
Connect the calendars you already use
Google and Microsoft, as many accounts as you have.
Gwork@...
Gpersonal@...
+ add
02
See everything in one view
Every account in one place, color coded by source.
03
Time blocks itself
Book anywhere and Busy appears everywhere else.
Setup takes under sixty seconds. Disconnect anytime and your calendars are exactly as they were. See how leaving works
The copying, the checking, the decoy blocks: all of it stops. The time you spent managing calendars goes back on the calendar.
Compare
One tool does the blocking.
Partial means the tool shows multiple accounts side by side. It does not write blocks across them.
Booking included
It takes bookings too.
One booking link, checked against every calendar you have.
A standalone booking tool sees one calendar. Kaiju sees all of them, and booking pages are included in the plan. No separate subscription, no Calendly bill.
Built on trust
Encrypted. Revocable. Yours.
Busy
Tokens encrypted at rest with 256 bit encryption.
Tokens never reach your browser. All calls happen server side.
Tokens stripped from logs and error reports.
One click disconnect removes placeholders and revokes access.
Export everything on cancellation.
Refresh tokens rotated automatically.
Why we built this
I run a marketing agency, and my work calendar kept booking straight over my personal life. I was double booked every few weeks. I looked for something that would just block my personal time on the work calendar automatically, without making me abandon the calendars I already used. Nothing did. So I built it.
