Permissions to grab the data in your phone. When you authorize the app by installing and agreeing to terms you are giving a green light for it to suck up all the data you have put in the device as well as anything you do ongoing. That means the app tracks your current location, purchases through your phone, contacts list, email accounts, etc, basically anything inputted into your phone the app has access to, except for the walled off stuff that Apple protects, like unique thumbprint or facial recognition ID. About 95% of the stuff in your phone is up for grabs with that app.
Yeah but it’s not a fucking city dude, the comments are addressing the hyperbole in the comment.
