</div>Well it's been like it is for the last 4+ years! If you uploaded your GPS<br>
data and it wasn't visible at all then what use would it be in OSM having<br>
it! By the very act of uploading GPS data to OSM you are making a<br>
contribution. It's only the original uploaded trace file that is made<br>
available to the wider public if you wish or kept private if you wish not.<br>
<br>
Cheers<br>

I looked in a couple obvious places on the Wiki ([1] and [2]) by following the Help link on the upload page and the availability of non-public trackpoints is not mentioned anywhere. Perhaps that fact could be made overtly clear on the upload page (i.e., a checkbox with a disclaimer "I understand that by not checking Public it doesn't really mean anything") for the paranoid among us that had the illusion of privacy for something marked not Public.<br>
