This touches a semi-related nerve. When you share a photo on iOS there’s an option to remove exif data—or at least the photo’s location—but there’s no way to always have it removed by default. Really annoying and easy to forget. /rant
I think that you can at least choose for photos you take to not have location data at all in camera settings.
I found out because the feature of mapping of where your pictures where your pictures were taken did not work for me, because I stopped the camera from having location data.
I think the default is to remove everything. I like to archive nice photos and because of that always have to ask family members to resend the image with metadata enabled.
