You leave footprints wherever you walk. If you are in snow or fresh tilled earth the footprints are obvious, but they are present even on hard paved surfaces even if they are not as easily detectable. In a greater sense you leave footprints in life as well, whether you mean to or not.
The legislature and court system may debate about a right to privacy, but in the ultimate spiritual sense that really matters there is none. For in the last day all things will be revealed. It is said that character is revealed by what you do when no one is watching. Yet there is still a permanent record of all things. Live every day as one who will give an account for every idle word and action.
