- -Agenda widget.- (disabled until #373 and #374 are fixed. Use [Calendar Widget](https://f-droid.org/de/packages/com.plusonelabs.calendar/) as an alternative.)
- 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](https://ownyourbits.com/2017/12/30/sync-nextcloud-tasks-calendars-and-contacts-on-your-android-device/) provides a tutorial how to use Nextcloud + DAVx5 + Etar.
### Technical explanation
On Android there are "Calendar providers". These can be calendars that are
synchronized with a cloud service or local calendars. Basically any app
could provide a calendar. Those "provided" calendars can be used by Etar.
You can even configure in Etar which ones are to be shown and when adding
an event to which calendar it should be added.
### Important permissions Etar requires
- READ_EXTERNAL_STORAGE & WRITE_EXTERNAL_STORAGE
->import and export ics calendar files
- READ_CONTACTS
->allows search and location suggestions when adding guests to an event
