set profiles as private

Hi, I'm in a project where I need to configure the CB so that all users are private, that is, the profiles can only be accessed by the profile owner himself and by levels above, that is, a registered user cannot see the profile of anyone else user,

What would be the best way to do this?

CB Privacy is specifically designed for accomplishing that.

You can also try setting "Profile View Access Level" to something like "Special". This makes profile access higher than a regular user would have but it can cause adverse effects in some features and isn't recommended.

I have this CB Privacy and it looks amazing

but as it has a huge amount of tweaks I'm afraid of doing something wrong,
although everything seems to be very self-explanatory,

Could you please tell me what setting I can make it for this?

I cannot provide support for paid products without an active subscription. You also do not have any recent download history for CB Privacy so if using a very old version the parameters maybe wildly different, sorry. Suggest taking a look at CB Privacy on our demo site and exploring it there. Alternatively you can subscribe and post in the support forums and will be glad to help you.
