I've been using a standalone opensource privacy-focused android calendar called KashCal. You can add remote calendars and keep them synced if you want, it's in very active development. I did find a bug that prevented me from saving an edit to a recurring event and dev replicated and confirmed the bug and promptly addressed it. Very stable useful app from F-Droid/GitHub.
