The answer is simple, we don't ask for ANY confidential information. When you sign up to use our app, you simply provide your First Name and Last Initial, nothing more. So we have no idea who you are. You can add your avatar, but you don't even need to pick a real picture if you don't want. It's 100% anonymous and confidential.
NOTE: If you choose to create an account, connect with Facebook or Twitter, or otherwise provide personal identifiable information we promise not to share this with anyone without your consent.
