Hi everyone

I'm trying to degoogle as much as possible. I've heard about this thing called calDAV and cardDAV but I have no idea how to use it.

With radicale, do I need to install some other somewhere in order to use it?

I'm just looking for basic useage for myself only at this stage. I'd like to be able to self host my own calendar and contacts. Is radicale appropriate for this?

Is it safe to self host a calendar?

Can a self hosted calendar still send and receive invites to other calendars?

Any help greatly appreciated, thank you
