  • About Etar

Store your calendar on the phone only:

  • Use offline calendar to create a local calendar on your phone.

Sync your calendar to a server

  • A cloud-synched calendar could be a google calendar, but you can also use
    any other public Caldav-server or even host your own (which would be the
    only way to keep full control over your data and still have ONE calendar
    usable from different devices.) To sync such a calendar to some server you
    need yet another app, e. g. DAVx5. That’s necessary because a Caldav client
    isn’t included in Etar.

The following link provides a tutorial how to use Nextcloud + DAVx5 + Etar.
