I have recently started using Mailbird as an email client, which uses
Google Calendar for appointments etc. I keep reading about Google
personal data hoovering, and was wondering if the calendar does the
same. I do not see that it is any business of Google if eg I have a
doctprs appointment in a weeks time.
It's not really practical to encrypt the appointment content.
If caldav worked by pulling down the entire database each time,
things might be different.
If you had a third-party calendar app, that worked with OneDrive
or Dropbox or whatever Google offers in the same way, then they
might decide to encrypt the whole database, before it's uploaded.
You could do encryption at the appointment level. As a crude
(easily broken) example, you could use ROT13.
Doctors appointment 2PM
which would become

But that's not all that convenient for viewing later.
If you were to use RSA2048 on that, the encrypted text would
likely be a lot larger than the input text.
This method is unbreakable, and the message size is the
same size as the encrypted text
You'd need to find a calendar product that is
Cloud based, but offers encryption of the appointment
database so no third party (nor in-flight) can observe it.
Then, all viewing screens could be in plaintext, no
ROT13 or anything else.
