I’ve moved away from google for my contacts and calendar. Now I use radicale as my sync server. Because of dynamic IP from my ISP I ran into multiple ussues like server unavailable at times of need and possibly lost contacts on my Android phone.
I’d like to try to use syncthing to do the syncing (like it already does for my photos). With its decentralized structure a sync node can be offline or temporarily unavailable and it still wouldn’t matter.
I can’t seem to find any apps on android that can automatically import/export changes in the calendar or in the contacts to a specified file. Or even specify the file in question.
My second place to use the contacts/calendar is Thunderbird under linux. Manual import/export just isn’t as just having a server connected using CalDAV and CardDAV.
Has anyone tried something like that or can give me some pointers on where to start?
