- Where the child goes to school, and his teacher's name

- Where and what day and time the child takes karate lessons
So: If you want it to truly be private, don't put it online. Don't be surprised if you learn that someone has harvested your email address, or used Google street view to get an idea of your income, or allowed some third-party app to access data it shouldn't. (And don't be naive: Making a call? Your phone knows where you are. Buying gas or eating at a restaurant? Your credit card company knows where you are and what you're doing. In your car? OnStar knows where you are.) Don't allow others to tag you in photos. Turn off the geotagging feature on your smartphone. Disable Facebook Places. Don't download every Facebook game and app and gift. Don't announce when you'll be out of the country for 2 weeks. If you don't want Facebook to have it, then don't give it to Facebook.
