Caldav/cardav are the standard protocols used in this case. So every sane provider uses them. Davx5 creates a local account and interacts with the android apps (like google calendar) by pulling/pushing new events from and to the server respectively.
So, I can keep using google calendar, with my FM account instead of google 👍 noice!
Thx for the info, didn't know DAVx5 was free on f-droid.
why do you want to host another
That's the thing, that I don't really understand. I thought I could host a centralized caldav/cardav server, and link all the other services that have their own "implementation" of contacts/calendars. This way, if I move away from Fastmail, I could just link another mail provider, that offers their calendars/contacts.
Well, you see... according ro IDF, the hamas are hiding within these peoples anuses. So they need to electrify their rectums, to get these guys out there. I mean, it's obvious, duuugh!
Literally no one is blaming all Jewish people in this case.
The Israeli government are Nazis, the IDF are Nazis and everyone else (no matter their religion, race, etc.) who supports this genocide is a Nazi. Period!
The problem, in this special case, is, once you point a finger towards Israel (or any other Jew who supports that), they use anti-semitism as a shield, they - disrespectfully - use the Holocaust as a shield.
Compared to electron it is lightweight. i.e. it doesn't include full Chrome, but a webkit webview, which also has its caveats, but does the job just fine.
