No user data will be saved after the session, shared, sold or used in any way which could be deemed undesirable. This app exists solely for the purpose that a user may query their own friendship network and get information on how they’ve been interacting with their friends.
Note to anyone stumbling upon this post or receiving an email about it (I hope this hasn’t happened!) – I am experimenting with the Facebook Graph API, with the hopes of being able to build a tool to investigating how much you’ve been interacting with your various friends. Please disregard for now! I’ll wrote a post on it if it ever works 🙂
