To App or not to App?

Ok... I am torn with this whole Facebook Messenger app thing.  I have a lot of customers who do not have my personal cell or heard from a friend that I was a consultant so they search for me and send me a message.  I have found quite a few of my customers have found me using that form of communication.  I deleted the app once all this started and then found at a certain point last week I wasn't able to read my customer/hostesses messages so I was forced to redownload the app to read and communicate with them.  Ugh.  I don't think Facebook is going to find my life that important to hack into my phone and spy on me but I do find myself worrying about who they sell my info to.  I get enough people who have my name through my business and try to contact me and sell me something.  (hello I am in sales too but I don't harass people).  Ugh.  I like having the option for people to find me if they want to.  Oh so much to contemplate. For now I am handing my stats over to the big boss called Facebook.  Ha!
