privacy settings on rendered page

I have a list of fields, i.e. firstname, middlename, lastname.
The fields are hidden on the profile page but visible on edit profiel page

On the user profile page I rendered the names like [firstname] [middlename] [lastname] with subtitutions by using a custom field cb_name_front

When I enable CB Privacy on i.e. the Firstname the settings are not displayed on the 'edit profie' page

I can only set the privacy settings on the cb_name_front field because it's visible on the frontend profile page.

Is it possible to set privacy settings on i.e. 'middlename' and 'lastname' to private so the rendered field cb_name_front only shows the firstname?

Yes, move firstname, middlename, and lastname to a tab that's in a not shown on profile position then set those fields to display on profile. Next replace your [FIELD_NAME] substitutions with [cb:userfield field="FIELD_NAME" /] usages. [FIELD_NAME] substitutions always output raw database values and ignore access checks, which is why they ignore privacy while userfield substitutions will respect access and privacy. See the below tutorial for further substitution usage information.

I set privacy for my email to private.
The user can't see the emailadress on my user profile page.

On top of my canvas is a tab 'messages' to send message with uddeIM and send email to user.
The emailadress on this tab is visible to all users.

I tried to disable this by Settings - general - don't display e-mail.
Now I can't see any emailadress

Does the menu "cbMenu_UE_MENU_SENDUSEREMAIL" respect the privacy settings? Is there a workaround?

Does the menu "cbMenu_UE_MENU_SENDUSEREMAIL" respect the privacy settings?

Correct.

Is there a workaround?

Beyond turning it off, no. You can disable it within CB > Configuration > General by setting "Email Handling" to something other than "Display Link to Email Form".

With the way CB Menu currently functions it may not be possible for me to protect that from CB Privacy until CB Menu usage has been rewritten, but I've added a feature ticket to see if that can be implemented.
