Peergos is an encrypted personal cloud and the calendar is one part of it. Everything is end-to-end encrypted, your events included, and the server is open source so you can run the whole thing yourself and be the only one who can read it. Events are standard .ics files you can import, export, and share by link. It is broader and more experimental than a plain calendar app. Its Windows and macOS apps now offer CalDAV and CardDAV sync for desktop calendar and contact apps, and its Android app syncs calendars and contacts into the phone's own apps. It suits people who would rather own the server than rent trust.
Strengths
- End-to-end encrypted, events included
- Server is open source and self-hostable
- Standard .ics import, export, and link sharing
Considerations
- Calendar sync to other apps needs the Peergos desktop or Android app, and there is no iOS app
- A broader platform to learn than a single calendar
