Cloudless Version
<a href="https://f-droid.org/repository/browse/?fdid=nl.mpcjanssen.simpletask" target="_blank"> <img src="https://f-droid.org/badge/get-it-on.png" alt="Get it on F-Droid" height="80"/></a>Cloudless stores tasks in a todo.txt file on the device. A separate app (such as Syncthing) can be used to Sync the file.
Because the todo.txt file could be anywhere on the device to allow sync by a different app, the Cloudless version requests full storage access. This is unfortunately the only way to make common use case work while staying sane.
Nextcloud Version
<a href="https://f-droid.org/repository/browse/?fdid=nl.mpcjanssen.simpletask.nextcloud" target="_blank"> <img src="https://f-droid.org/badge/get-it-on.png" alt="Get it on F-Droid" height="80"/></a>Nextcloud stores tasks in a todo.txt file using Nextcloud.
WebDAV Version
<a href="https://f-droid.org/repository/browse/?fdid=nl.mpcjanssen.simpletask.webdav" target="_blank"> <img src="https://f-droid.org/badge/get-it-on.png" alt="Get it on F-Droid" height="80"/></a>Nextcloud stores tasks in a todo.txt file on any WebDAV server.
