You can replace the ossn_com.php of your component with following file:

yes

Do you wanted to hide About User menu ?

i have this

 if($params['user']->fullname == ossn_loggedin_user()->fullname){
blablavbla
}  else {
echo 'keine Berechtigung';
}

 in actionfile 

but i want to hide the menue, so no one can see the link only profile owner. and if some one gose direct to u/xxx/subsite he got "echo 'keine Berechtigung';'

You can use the condition to check if loggedin user is the profile owner

if(ossn_isLoggedin()->guid == $user->guid){
    //show my stuff
}
