When setting up a Bushel account, we require you to setup a certificate between an Apple ID and your Bushel account. This is a little file exchange that protects your data with Apple. No other Bushel user (and certainly not we who run Bushel) can access your secure connection with Apple. When you’re first setting up a Bushel account, you’ll get prompted to configure a certificate. That’s done by downloading a file from us and giving it to Apple (to prove our authenticity to Apple) and then downloading another file from Apple (to prove their authenticity to us).
