One problem I find with these tracking applications, at least for the average users, you actually have to remember that: (1) you have one installed and (2) your credentials.

It's kind of a problem, if you have all your other data stored using something like 1Password.

I know for sure I have a tracker installed on my laptop, but since it's running in "stealth" mode, I have no clue what it is or where to find it. I guess I am not hacky enough.
