"Niemand kommt in deine Nähe."
Yes, thanks, I will edit the comment! :)
There are some exceptions, anyway... you can say "Ich spaziere im Garten" if you walk but don't go out of the garden, even if you move... it's more complicate than I thought... sorry!
Let's see if some native speaker can help a bit better. :)
Nobody comes near you - is the best English sentence... but...I think if "vicinity" is used the English "No one comes into your vicinity" should be at least accepted - otherwise it sound like, well that the coming is more important than the vicinity is the best way I can describe it OR it just doesn't sound right to me as a UK English speaker.
