Cloud support

[ramack]

The app shall support different devices and therefore (optionally) store the data on a server in the cloud. Choose a server model to support that or implement an own server to synchronize with.

The best seems to be to provide a RESTful server in PHP storing data in a MySQL database. Maybe use https://github.com/mevdschee/php-crud-api or the tutorial in https://www.codeofaninja.com/2017/02/create-simple-rest-api-in-php.html

Important: the app shall be fully usable without network and sync on mobile or WLAN (to be configurable) and also completely without cloud connection.

An alternative idea was suggested by Michael to use a standard format like ical where then existing server implementations using caldav could be used for synching to multiple devices etc. Challenge here is to support additional things like

• list of selectable activities
• position traces
• images

maybe cloud sync is not necessary for Release 1. Let's shift it to v1.1

[ramack]

as you see, v1.1 did not have it, and obviously some other issues have priority over this one.

Nevertheless another potential sync option could be to use ical/DAV with existing calendar synchonization...
