Bizarre question.

You can gather statistical data for an "app" (meaning software installed on a users personal device holding that holds their private data) without tracking users or invading their privacy.

It may be possible, but it be nearly impossible to make money off of it, which is why nearly every app/website has a consent prompt.

I love how every argument is like "this extremely rare and practically useless application is possible, so you don't need cookie prompts".
