Not concerned. Nothing on there to hide. I just don’t want it there because if I post what I think about what’s going on, I’m going to be unemployable.
If you deactivate and keep it deactivated (I suggest you delete the app from your cell phone) no one can see what you wrote in the past and you wont be able to write anything new until you log into it again (I think just merely logging in will reactivate it).
