Hey guys! Thanks for sharing this. I'm actually in the process of starting something similar. What is your approach to ensuring data security for your clients? That's one of the biggest open questions we're always improving.
Data security is hugely important. Here are a couple things we do to deal with it: (1) We cleanse the data of Personal Identifiable Information (PII) as quickly as possible (i.e., before it touches our servers), and (2) We host our databases behind secure networks and follow best practices with regards to authentication, encryption, etc.
