Oddly enough, many "applications" are a bunch of javascript code, html markup and css styles. All this economy is remotely downloaded from the server every time the "application" is opened and displayed in the browser built into the system. And all the work and manipulations with information are performed on the server using ajax, websockets, long pooling and json.

And in fact, as such, there is no application, in the traditional sense of the word. And there is an api for interacting with the server! Knowing how the api and server access keys work, you can extract information without installing the application.

Typical cases with manufacturers of children's smart watches. Search the Internet for information on the users of these products. For example, the site habr.ru is full of articles on this topic.

I doubt that this is possible at all. Applications have clear scripts for actions, reactions and interactions.

Inside each application, it is written where what should be saved, what should be installed where and which components to which libraries to access. If you try to launch something without having at least one more or less significant file, launch the program, it simply won't launch.

Google, however, has an option: web applications. But they still need some space on the phone / computer, the same Cookies and cache.

There is still a solution if you need information about the application itself: view its data in Google Play, App Store or Marketplase. Or go to GitHub.

To summarize: this is almost impossible, but there are alternatives.
