In Apple's App Store: when I write a review of an app, what info about me can the app's developer see?

As far as I’m aware they can see your username (typically your email address without the @...com), the date and time you posted it. And possibly the country you’re from. I don’t quite recall if it picks up any data like that. It would only be an issue if you’re already sharing your location publicly.

Is there anything in particular you’re concerned about? Or just wondering?

They have your contact information.

whitetigress, do you know which contact information?

I have a few apps in the app store. I will just say this. We don’t have enough info to burn your house down if you give a bad review. Don’t worry.

Could anybody please be specific? Specifically what contact info do the devs get? Please help me on this.

This isn’t a joke for me. Please help me find out exactly what info about me a dev knows if I posted a review of their app.

Not much more than anyone else can see. This is actually a problem with the app store model.

Apple keeps user data under lock and key from pretty much everyone. This keeps app developers and users from creating and fostering relationships.
