Auto fill address wrong

i just noticed the last couple of times I bought something online, that the address was wrong by one house (two numbers eg 524 instead of 526). It’s pretty embarrassing, each time I noticed as it was placing my order and the info was leaving the screen. So I had to contact the companies who were very good about it. I went into my contact information and Apple has GPS tracked me to find out where I live. It had also gone into my (very) private and personal emails to find out my email address, and I assume those of my contacts. I couldn’t believe it, I think they had picked up the most personal email I have ever sent to remain forever in my contact information, now that takes talent. I thought Apple was a lesser evil than Google, now I’m not so sure. As maps always has me at the address next door, can’t that be more accurate? So contacts had me at the address next door, and then autofill has me at the address next door. Silly, silly. I did work out how to fix it, go into contacts choose ignore and then edit, but it’s not such a clever feature, and it’s pretty invasive. Can’t you just let us fill in our own details, and never try to derive them from information that should be private.
