Most of us have been on Facebook for many years, which means that there's bound to be a number of companies that have access to our profile from old interactions. There are a couple of ways that a company can gain access to your profile, mainly through apps or when you use Facebook to login to another website. Even though you may not be using the app or service anymore, you actually gave them permission to continuously access your profile info. If you haven't reviewed the companies that currently have access to your profile in a while, you may be in for a surprise. Our suggestion is to review who has access on a monthly basis, so you can keep it to just the apps and services you want to use.
