Hey, thanks for your app submission! There's a few issues here that need to be resolved before it can be published:

• Your application ID needs to reflect a URL that you have permission to write to. It can't start with "io.elementary". If you have a website it can reflect your website, otherwise it can reflect the url of your GitHub project page like io.github.alexxisaapps.elementary_goal_tracker. See also: https://www.freedesktop.org/software/appstream/docs/chap-Metadata.html#tag-id-generic

• It looks like your app is using the Adwaita stylesheet. It must use the elementary stylesheet to be published in AppCenter. You can make sure that the Adwaita stylesheet isn't loaded by calling Granite.init () before Adw.init () during your app's startup

• your app requests some file system permissions it shouldn't have. You have hardcoded some file paths in your app instead of getting the correct paths inside of your app's sandbox. You should use GLib to get the correct paths. See also: https://valadoc.org/glib-2.0/GLib.Environment.get_user_data_dir.html and related functions

• Your application should add its stylesheet as a custom resource instead of installing it to the filesystem. See this documentation section on custom resources: https://docs.elementary.io/develop/apis/gresource. Granite.init () will automatically load a resourced stylesheet named "Application.css"
