Nextcloud support

[dm-m]

It would be great if Haven could upload all recorded information to a custom server with Nextcloud instance.

SMS and Signal might not be the options for true security. SMS is totally insecure and easy to intercept. Signal server component is not open source and uses GCM to carry meta information.

Please consider Nextcloud as one more option for transmitting sensitive data.

SMS can be encrypted, see https://github.com/SilenceIM/Silence (name crypto as Signal)

Also, Syncthing does not need special support, share folder and done.

(Regarding Signal, the server component is open source. GCM is only used when using an Android phone that has play services anyway and you can use the websocket version alternatively.)

But the request to have uploads for example to Nextcloud still sounds reasonable. Maybe it's a good idea to generalize this to WebDAV uploads. This would allow uploads to arbitrary WebDAV servers, using the standardized protocol, which Nextcloud supports.

On the other hand, just using dedicated apps for this, like the official Nextcloud app, could also work if haven saves everything in a folder and the (Nextcloud) app would allow to sync arbitrary folders. This would be the same as in the already mentioned Syncthing scenario.

@licaon-kter It can be encrypted but I'd rather use special e2e encryption solutions like OMEMO for such data.
@exploide Sorry, meant redphone here, not the text messaging part.

Redphone is no longer part of Signal, it got replaced by a WebRTC implementation earlier in 2017.

@dm-m See #21 for OMEMO

I think this issue can be marked as solved as nextcloud syncing does work out of the box with "custom folders". nextcloud/android#285

If you install the Nextcloud client on the same phone, it can be configured to automatically upload any folder on the phone to Nextcloud. May this be an option?
