Yes! You can control your profile's visibility through the Private Profile setting in My Profile.

When Private Profile is enabled, visitors will only see your avatar and username (@). Your display name, Loot Rewards tier, membership date, and collections will be hidden from your profile page.

Please note: Making your profile private does not make your public collections private. Public collections can still be accessed through their direct links.

To restrict access to a collection, you must make that collection private separately.
