I am none of your business.
If i run an e-commerce site, and see the vast majority of my users, but the minority of those that buy stuff, are on mobile and from India, maybe i need to optimise my site for mobile and lower-speed connections? Maybe something is wrong with my payment for specific currencies?
If i run a blog, ans the majority of my viewers come from France, maybe it's time i start writing localised content in French?
You get the gist.
Also, look at both of your examples. They’re bad. They’re both best replied to with that diagram of holes on a WW2 airplane.
Who I am is not.
You don't need to know if I have kids, have a disease, my age, my race, my gender. You don't need to know anything. Sure that information would help you make a better experience for me, I get that. But that's up to me. If I want a better experience, allow me to provide that information in exchange for the benefits that information gains me. But peeking over my shoulder as I walk through your store so that you can overanalyze everything I do isn't okay.
