Radicale just implements CalDAV and CardDAV so use any clients you want.
I’m mostly using the Fossify from F-Droid - their calendar, contacts, all work with DAVx5 syncing to radicale and it works fine… no 3rd party tracking my dentist appointments.
I also have TrackerControl running on my phone, so I know that there’s no tracking.


I’m kinda with you, with a slight change: raspberrys that can’t run Arch Linux on Arm run Raspberry Pi OS, so, almost Debian.
Everything else: Arch.
(Oh… and pfSense on FreeBSD… but let’s not muddy the water)
