Yes. As long-time software professionals who have spent years building enterprise financial software, we take security seriously. We don't have access to your Amazon credentials, so we can only see what you agree to share and no one can steal your password from us.
We use two-factor authentication internally whenever we access our systems to prevent social engineering based attacks. And when we communicate with you or Amazon we use encryption protocols meeting industry-leading data safety standards and that support perfect forward secrecy (PFS).
We will never share or sell your data.
