When you enter a new country do they report your entry to your home country? Do countries track where their citizens are?

Please edit the question to limit it to a specific problem with enough detail to identify an adequate answer. Avoid asking multiple distinct questions at once. See the How to Ask page for help clarifying this question. If this question can be reworded to fit the rules in the help center, please edit the question.
There are currently 7376850 different combinations of citizen from "country A" travels from "country B" to "country C" so it's almost impossible to give a comprehensive answer.
However, in most cases the answer is "no". If you are a US citizen, crossing the border from, say, Denmark into Sweden, neither Danish or Swedish authority would report anything to the US authorities.
Countries typically keep track when you arrive and when you leave, but exchange of data between different countries is fairly rare.
