I wanted to submit this to the brilliant people of Hacker News hoping to get some constructive feedback.

I am writing a couple blog posts on the design process. The first one is located at: http://blog.shuteye.co/post/61493917659/designing-a-product-to-be-as-private-as-possible

The project is live, but the charging of credit cards is fake at this time. To 'purchase' sessions use the credit card number '4242 4242 4242 4242', any valid expiration date, and valid CVC code.

Thank you everyone in advance for your feedback.
