Which Bitcoin app does not need ID verification?

I'm curious to know, could you please elaborate on which Bitcoin application or wallet does not require identity verification? As we all know, the cryptocurrency landscape is constantly evolving with new regulations and security measures, so finding a secure yet convenient option that doesn't mandate ID verification can be challenging. Are there any popular or reliable Bitcoin wallets or trading platforms that allow users to transact without needing to disclose personal information? If so, what are the key features and benefits of using such an application?
