You chose to be friends with someone on Facebook which means you very explicitly chose to share your personal details with that person for them to consume or view it in whatever way they saw fit. It was very much clear from context at the time that they would consume it from multiple different sources: the website, phone-specific apps, shared games, etc. Once someone knows something about you, it's no longer yours; it's that person's to do with as they please.
