What this applies to
This is for additional profiles , ones you’ve created alongside your own main profile. Your account’s own main profile can’t be deleted this way; see Deleting Your Account if you want your own profile removed entirely.
How to delete one
From your account page, find the profile in your profile list and select “Delete.” You’ll be asked to confirm, because this cannot be undone.
What happens to devices linked to it
Any devices assigned to the deleted profile are unassigned, not deleted. They’ll stop showing any information until you reassign them to a different profile on your account. See Assigning a Device to Your Profile.
Before you delete
Consider whether you actually want to keep the profile but simply hide it , deleting is permanent, so if you might need the information again later, it may be worth keeping the profile in place with its devices unassigned instead.
