How does Bonsai keeps my bank information safe?

While sensitive data is usually stored with partners (like PayPal or Stripe), in the few instances where we store sensitive user data everything is encrypted using OpenSSL’s implementation of PBKDF2, a high-level algorithm that is designed to be intentionally slow to prevent brute-force hacking attempts.  PBKDF2 is a function currently used by apps such as 1Password, LastPass and Apple’s iOS operating system.  

Along with database and app-level encryption, our website uses SSL to prevent packet sniffing of user data over the internet.
