Private email calendar solutions that sync across your devices without needing technical know-how havan't been around until recently. This is at least to my knowledge. I found out about Tutanota, an email service similar to ProtonMail but with a private calendar as well.

There is no desktop client, but this is a service I've been wanting to see for some time, and I'm excited that it's here!
