Chrome has a lot of "hidden" tricks and treats, and one of them is the Chrome's Built-in URLs. A bunch of internal URLs designed to provide advanced information, debugging and detailed info about you and the browser. Yes, information about you, since you are using the browser. A built-in URL follows this schema chrome://{address}. Here i will list 3 of them that i consider very cool to take a peek. My Current Google Chrome version is 80.0.3987.132 (Official Build) (64-bit), under a Linux Ubuntu.

chrome://user-actions/

When opened, log the user events (activity) on the browser, but do not seem to store any data about it.
