Checking who checks your profile on Facebook, unfortunately, is not a feature the platform offers to its users. However, there are third-party apps that claim to provide this functionality, but it’s important to exercise caution when using such apps, as they may not be reliable or secure.
It’s generally not possible to know who views your Facebook profile, and Facebook does not provide a way to track this information. This is a privacy measure to protect users’ data and prevent potential stalking or harassment.
