“Anonymous” app After School does not have typical privacy settings because users do not have a profile that can be viewed or shared. All user posts are by default anonymous unless a person includes his or her name in a post. After School outlines its privacy policies on its website. For more, see ConnectSafely’s A Parent’s Guide to After School.
Facebook has a privacy settings page but it also has “in-line privacy” settings for each post. Each time you post, there is an icon such as a globe for public or other image to indicate if you’re sharing with friends, friends of friends, only me, specific friends or a custom list. This gives you an enormous amount of granular control. You could, for example, create a list of friends or family members and send a specific post just to them. Note that this setting is sticky so it stays in place until you change it. If, for example, you decide to post something to Public, you’ll need to change it back to Friends or whatever you prefer, the next time you post — otherwise that post, too, will be public.
Google has numerous services that can be viewed and changed on its Control, protect, and secure your account page. Google also has a Privacy Checkup that allows you to review and adjust your settings and a page that lets you review and delete a record of your Google activity.
