Strava allows users to create a privacy zone around address, for example, I have a 1/2-mile ring around my house where no other user can see my route.

I don't have big $$$ bikes, but I don't post all the details about my bikes - some users like to 'brag' about their awesome bikes (read big $$$), letting a thief know that there's something really good to steal.

Lastly, users can make their Strava account private and use it as a person riding log.
