I have used private inheritance. The base class public access members are still public access in the derived class. Therefore the derived class still can call the base class functions and access its public data. But the user who instantiates the derived class, cannot access the public member of the base class, hence private inheritance.

Public inheritance is a "is-a" relationship.
Private inheritance is a "implemented-in-terms-of" relationship.

A useful example, is I like .NET string class and like a C++ string class with the same C# methods but I do not want to reimplement from scratch, so I derived from std::wstring with private inheritance to make use of its functionality, so that user of my string class cannot access the base class's std::wstring to avoid the confusion.
C++
class MyString : private std::wstring
{
};
There is an excellent blog about this topic: C++ Tutorial: Private Inheritance - 2020
