Our process for safeguarding credentials is mentioned further down in the thread.
I'm not sure what more guarantees we can give to inspire confidence other than statements taken at face value. We don't have the scale or resources to undergo rigorous third party auditing at the moment. On the other hand, one of the first conversations my co-founder and I had was about hiring a security engineer as soon as we could afford one; we definitely take the matter seriously. Did you have any other ideas of ways we can showcase our commitment to security/privacy other than "trust us"? I do agree it's not the best method but am unsure of alternatives.
