Superdense has 2 view: The app and your public profile. In edit mode (bottom right button) you can decide which categories you want to show on your public profile and which you want to keep private.
⚠️ The categories in free trial are limited to 'Public' only. If you have bookmarks you want to hide from your public profile, you will need to sign up for a subscription.
To toggle between public (default) or private, enter edit mode and click the eye-icon.
Open eye means it's publicly visible on your public page (superdense.com/your-username) and

And back in the regular view of your page, you can see a little colored dot indicating whether the category is public (green'ish) or private (red'ish):
To save your changes, click 'Save' in the bottom right corner. Or select 'Cancel' to discard your changes.
