Thank you for your quick response. I think I explained my situation wrong (sorry for my English, I need a translator to help me).
Since a few years ago, I have been incorporating open source software in my work and in my daily life. Recently, I decided to look for alternatives to Google to store and sync contacts, calendar, etc, in Thunderbird and Android/Lineage OS.
I’m not an advanced computer user, and I don’t know any computer programming languages either. I usually set up my computer using tutorials and internet forums.
Searching the internet, I found this: https://ownyourbits.com/2017/12/30/sync-nextcloud-tasks-calendars-and-contacts-on-your-android-device/
Using this and other tutorials, I installed Nextcloud, Davdroid, etc. When you create a Nextcloud account in the cloud, you choose a hosting service. I thought, “ok, woelkli is fine, go ahead”. Some time later, I read that it was possible to include other apps in Nextcloud, like Notes (which I installed in the smartphone), or News, to add feeds. But in this case, I didn’t see the possibility of installing this app in woelkli, and I don’t know if it’s possible or not, if a better account is needed, etc.
I insist. I don’t want to do anything illegal, no piracy, etc. From what you tell me, the free storage service offered by Woelkli with Nextcloud does not include the possibility of adding other apps. In some websites I have seen that it is possible to add new functions to Nextcloud, I just didn’t know that in some storage services this is not possible. My question was: am I doing something wrong? Why can’t I add this?
So, now my question is: as a “standard” computer user, what could be a good option to have nextcloud with some of these functions, without a high cost?
Thanks for your time and knowledge
