What does TCC stand for Apple?

Excuse me, could you please clarify something for me? I've come across the acronym "TCC" in relation to Apple, but I'm not entirely sure what it stands for. Is it a technical term specific to Apple's products or services? Or perhaps it's related to a certain aspect of Apple's financial operations? I'd really appreciate it if you could shed some light on this for me. Thank you in advance for your help.
