1. Personal Information
To create your account, I have to store some basic information. I have tried to collect only what is needed. An email address is the only thing I require because obviously, the site would not work otherwise. Your name and phone number can be stored, but they aren't required. If you update your account information, having those pieces of information will make it easier should I need to contact you or vice versa, but you are under no obligation to share them.
Your use of this site is completely confidential. I may share summary statistics about number of users, but I would never share any information about the individual users without their explicit consent.
